description: We establish the existence of analytic curves of eigenvalues for the Laplace-Neumann operator through an analytic variation of the metric of a compact Riemannian manifold $M$ with boundary by means of a new approach rather than Kato's method for unbounded operators. We obtain an expression for the derivative of the curve of eigenvalues, which is used as a device to prove that the eigenvalues of the Laplace-Neumann operator are generically simple in the space $\mathcal{M}^k$ of all $C^k$ Riemannian metrics on $M$. This implies the existence of a residual set of metrics in $\mathcal{M}^k$, which make the spectrum of the Laplace-Neumann operator simple. We also give a precise information about the complementary of this residual set, as well as about the structure of the set of the deformation of a Riemannian metric which preserves double eigenvalues.

description: Exact solutions of the SEIR epidemic model are derived, and various properties of solutions are obtained directly from the exact solution. In this paper Abel differential equations play an important role in establishing the exact solution of SEIR differential system, in particular the number of infected individuals can be represented in a simple form by using a positive solution of an Abel differential equation. It is shown that the parametric form of the exact solution satisfies some linear differential system including a positive solution of an Abel differential equation.

description: Spin-selective spatial filtering of propagating polariton condensates, using a controllable spin-dependent gating barrier, in a one-dimensional semiconductor microcavity ridge waveguide is reported. A nonresonant laser beam provides the source of propagating polaritons while a second circularly polarized weak beam imprints a spin dependent potential barrier, which gates the polariton flow and generates polariton spin currents. A complete spin-based control over the blocked and transmitted polaritons is obtained by varying the gate polarization.

description: Informed consent is a core cornerstone of ethics in human subject research. Through the informed consent process, participants learn about the study procedure, benefits, risks, and more to make an informed decision. However, recent studies showed that current practices might lead to uninformed decisions and expose participants to unknown risks, especially in online studies. Without the researcher's presence and guidance, online participants must read a lengthy form on their own with no answers to their questions. In this paper, we examined the role of an AI-powered chatbot in improving informed consent online. By comparing the chatbot with form-based interaction, we found the chatbot improved consent form reading, promoted participants' feelings of agency, and closed the power gap between the participant and the researcher. Our exploratory analysis further revealed the altered power dynamic might eventually benefit study response quality. We discussed design implications for creating AI-powered chatbots to offer effective informed consent in broader settings.

description: Mixed valence spinels provide a fertile playground for the interplay between charge, spin, and orbital degrees of freedom in strongly correlated electrons on a geometrically frustrated lattice. Among them, AlV$_2$O$_4$ and LiV$_2$O$_4$ exhibit contrasting and puzzling behavior: self-organization of seven-site clusters and heavy fermion behavior. We theoretically perform a comparative study of charge-spin-orbital fluctuations in these two compounds, on the basis of the multiband Hubbard models constructed by using the maximally-localized Wannier functions obtained from the ab initio band calculations. Performing the eigenmode analysis of the generalized susceptibility, we find that, in AlV$_2$O$_4$, the relevant fluctuation appears in the charge sector in $σ$-bonding type orbitals. In contrast, in LiV$_2$O$_4$, optical-type spin fluctuations in the $a_{\rm 1g}$ orbital are enhanced at an incommensurate wave number at low temperature. Implications from the comparative study are discussed for the contrasting behavior, including the metal-insulator transition under pressure in LiV$_2$O$_4$.

description: Cancer continues to have overwhelming impacts on human health and the development of new chemotherapeutics. Molecular hybridization has thus been valued as a structure-based drug design approach to drugs with enhanced efficacy. Herein, we report the multistep synthesis of quinoline–2-mercapto-1,3,4-oxadiazole conjugates and their cytotoxicity evaluation. Compound 4j 2-[(5-bromopentyl)thio]-5-[(quinolin-8-yloxy)methyl]-1,3,4-oxadiazole showed the best cytotoxicity to pancreatic (MIA PaCa-2) and colorectal (HCT116) cancer cells with IC50 values of 29.19 ± 0.99 and 75.10 ± 1.87 µM, respectively. The compound is also less cytotoxic to non-cancerous human primary dermal fibroblast cells with IC50 = 91.87 ± 1.29 µM compared to the parent compound 8-hydroxyquinoline (IC50 = 72.36 ± 4.23 µM). ADME properties prediction suggested the drug-likeness of potent compounds while molecular docking and molecular dynamics simulations with doublecortin-like kinase (DCLK1) revealed the compounds’ stable binding interactions at the kinase domain. Overall, the results illuminate compound 4j as a structural model to furnish new cytotoxic agents against pancreatic and colorectal cancer.

description: We calculate non-axisymmetric oscillations of neutron stars magnetized by purely poloidal magnetic fields. We use polytropes of index $n=1$ and 1.5 as a background model, where we ignore the equilibrium deformation due to the magnetic field. Since separation of variables is not possible for the oscillation of magnetized stars, we employ finite series expansions for the perturbations using spherical harmonic functions. Solving the oscillation equations as the boundary and eigenvalue problem, we find two kinds of discrete magnetic modes, that is, stable (oscillatory) magnetic modes and unstable (monotonically growing) magnetic modes. For isentropic models, the frequency or the growth rate of the magnetic modes is exactly proportional to $B_{\rm S}$, the strength of the field at the surface. The oscillation frequency and the growth rate are affected by the buoyant force in the interior, and the stable stratification tends to stabilize the unstable magnetic modes.

description: Homophone characters are common in tonal syllable-based languages, such as Mandarin and Cantonese. The data-intensive end-to-end Automatic Speech Recognition (ASR) systems are more likely to mis-recognize homophone characters and rare words under low-resource settings. For the problem of lowresource Cantonese speech recognition, this paper presents a novel homophone extension method to integrate human knowledge of the homophone lexicon into the beam search decoding process with language model re-scoring. Besides, we propose an automatic unified writing method to merge the variants of Cantonese characters and standardize speech annotation guidelines, which enables more efficient utilization of labeled utterances by providing more samples for the merged characters. We empirically show that both homophone extension and unified writing improve the recognition performance significantly on both in-domain and out-of-domain test sets, with an absolute Character Error Rate (CER) decrease of around 5% and 18%.

Insights from Zircon Geochronology and Trace Element Geochemistry on the Interplay of Plutonism and Volcanism within the Mount Princeton Magmatic Complex of Central Colorado
Creators: name: Thyer, Benjamin James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Combining high-precision CA-ID-TIMS zircon U/Pb geochronology with multivariate analysis of trace element data provides insight into the evolution of crustal magmatic systems. The Mt. Princeton magmatic center (MPMC) contains the largest Cenozoic batholith in Colorado (450 km^2) as well as volcanic rocks erupted from within or adjacent to the batholith boundary. Over a kilometer of vertical relief at the MPMC, caused by Rio Grande rifting and the collapse of the Mt. Aetna caldera, exposes a variety of volcanic and plutonic rocks, making the MPMC a well-suited locality to study the relationship between plutonism and volcanism. Here we present new U/Pb zircon geochronologic results for six samples from the MPMC which expand the duration of active magmatism for the system to 37.48 ± 0.18 Ma to 33.93 ± 0.08 Ma; excluding ~30 Ma leucogranites. The Calico Mt. Andesite flows and tuffs (37.48 ± 0.18) and the Mt. Pomeroy Quartz Monzonite (36.27 ± 0.09 Ma) preserved within the Mt. Aetna caldera collapse structure are interpreted as the earliest magmatism in the system. The age of the Calico Mt. volcanic rocks suggests they represent remnants of volcanic activity that predates all other dated rocks from the MPMC; and the age of the Mt. Pomeroy Quartz Monzonite places it as the oldest plutonic component of the MPMC. New U/Pb zircon geochronology results for rocks from the younger portion of the system suggest that the Badger Creek Tuff erupted at 34.35   0.08 and reveal complex zircon U/Pb isotopic mixing systematics within the Mount Aetna Quartz Monzonite. These new data along with previously published Ar/Ar ages provide evidence that subduction-related magmatism within the Mount Princeton Magmatic complex was active at least from 37.48 ± 0.18 to 33.93 ± 0.08 Ma, recording a systematic evolution from volcanism (37.48 ± 0.18) to large-volume plutonism (36.27 ± 0.09 to 35.37 ± 0.10) to ignimbrite related magmatism (35? – 33.93 ± 0.08 Ma). Integrated principal component analysis of trace element concentrations and high-precision ID-TIMS U/Pb geochronology reveals that these temporally distinct modes of magmatism also record distinct trace element signatures, suggesting that melt-producing processes are largely responsible for generating the chemical and temporal variation within the magmas of the Mt. Princeton magmatic complex.
Dancing is for All: The Impact of Dance Movement Therapy on Pediatric Populations with Neuromuscular Disruptions
Creators: name: Mykenzie Cochrane
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The purpose of this study was to review and analyze existing literature to determine if Dance Movement Therapy (DMT) is a suitable therapeutic option for children and adolescents with neuromuscular disruptions, specifically Down Syndrome (DS), Cerebral Palsy (CP), and Autism Spectrum Disorder (ASD). DMT has been researched identifying its benefits on physical and mental well-being, but limited research has been conducted for its use with non-healthy populations, specifically those with neuromuscular disruptions. Using PubMed and CINAHL databases, 12 articles were reviewed and analyzed using the John Hopkins Evidence Level and Quality Guide. Studies show that children with DS have had gross motor improvements and increased social interactions as a result of DMT. Children with CP who have experienced DMT had improvements in mobility, leading to greater independent functioning and overall well-being. Literature has shown significant improvements in social functioning, including communication and relationship development in children with ASD. Dance Movement Therapy has been found to have noteworthy impacts on physical, mental, and social well-being in children with DS, CP, and ASD; therefore, DMT should be considered as a possible therapy option. Further research is warranted to determine which type of dance genre, frequency, and duration is most effective

Structural analysis indicates that both HESs consist of a (nearly) single tetragonal W$_{5}$Si$_{3}$-type phase (space group $I$4/$mcm$) with a disordered cation distribution. Electrical resistivity, magnetic susceptibility and specific heat measurements show that (Nb$_{0.1}$Mo$_{0.3}$W$_{0.3}$Re$_{0.2}$Ru$_{0.1}$)$_{5}$Si$_{3}$ and (Nb$_{0.2}$Mo$_{0.3}$W$_{0.3}$Re$_{0.1}$Ru$_{0.1}$)$_{5}$Si$_{3}$ are weakly coupled bulk superconductors, which represent the first superconducting high-entropy nonoxide ceramics. In particular, these HESs have higher $T_{\rm c}$ values (3.2-3.3 K) compared with those of the binary counterparts, and their $B_{\rm c2}$(0)/$T_{\rm c}$ ratios are the largest among superconductors of the same structural type.

Nozick’s Self-Subsuming, Reflexive Agent: A Model for the Existence of Free Will
Creators: name: Martin, Hunter
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Assuming a causally determined world, it is difficult to find room for free will. Events generally are either causally determined, or, in the absence of causation, events are random. In Philosophical Explanations, Robert Nozick theorizes a reflexive and self-subsuming agent as a potential model for agency in which the agent may escape the causal structure of the world and achieve freedom. This paper explores this concept, using the selfhood as a model for a self-consumptive agent and considers whether and how an agent may actually achieve free will. This is done by first defining terms, in particular defining free will as a procedural quality which effects the way an agent makes decisions without necessarily changing the outcome of any particular decision. This conception of free will is used to unpack Nozick’s conception of a Self-subsuming and reflexive agent. This agent is then explained in practical terms using ideas about the emergence of selfhood in human agents and the nature of the experiencing self as a generator of value. Ultimately, I find this model to be very effective. While I do not find the self-subsuming, reflexive agent to be definitively free, I do find this conception to present a reasonable possibility for the potential existence of free will.

A time-dependent Markovian model of a limit order book

description: This paper considers a Markovian model of a limit order book where time-dependent rates are allowed. With the objective of understanding the mechanisms through which a microscopic model of an orderbook can converge to more general diffusion than a Brownian motion with constant coefficient, a simple time-dependent model is proposed. The model considered here starts by describing the processes that govern the arrival of the different orders such as limit orders, market orders and cancellations. In this sense, this is a microscopic model rather than a ``mesoscopic'' model where the starting point is usually the point processes describing the times at which the price changes occur and aggregate in these all the information pertaining to the arrival of individual orders. Furthermore, several empirical studies are performed to shed some light into the validity of the modeling assumptions and to verify whether certain stocks satisfy the conditions for their price process to converge to a more complex diffusion.

description: Excavated by prominent archaeologists Dr. Stanley South and Dr. Lewis Binford in 1955, the Gaston site in Halifax County continues to play an important role in the understanding of Native American lifeways 1,000 years ago in the North Carolina Piedmont. Excavations uncovered an unusually large number of domestic dogs (Canis lupus familiaris) that had been intentionally buried upon death by the human occupants of the site, but these dog burials have remained largely unstudied for over 60 years. 

This thesis seeks to analyze these canine remains by determining each dog’s age, sex, and skeletal health in order to evaluate their life histories. It places the 16 Gaston site dog burials within the larger context of dog burials found at sites across North Carolina, including two sites in particular with similarly large numbers of dog burials: Broad Reach and Contentnea Creek (also known as Wilson). This research desire to address two main questions: (1) Can any general patterns (temporal, geographic, cultural, etc.) be proposed from an in-depth study of dog burial distributions throughout the state? and (2) How do the dog burials at the Gaston site fit into these larger patterns?
Lifting the Cap: The Association between Charter School Prevalence and Hyper-Segregated Schools in North Carolina
Creators: name: Parker, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In 1996, North Carolina legislators passed the Charter School Act, allowing for the establishment of up to 100 privately run and publicly funded charter schools in the state. In 2011, legislators lifted the original 100-charter school cap, anticipating funding from the federal Race To The Top funding (USDOE, 2009). This study examines the history and context of North Carolina charter schools, the negative effects of racially segregated schools, and policy changes that could improve outcomes for students in the state. This study investigates the hypothesis that lifting the cap on charter schools intensifies the effect of the number of charter schools and the rate of charter school attendance on the prevalence of hyper-segregated schools within school districts in North Carolina. Accordingly, the two primary research questions of this study are: (1)  What are the effects of increasing charter school enrollment on the number of hyper-segregated schools in North Carolina school districts and (2) What are the effects of increasing the number of districts with at least one charter school on the number of hyper-segregated schools in North Carolina school districts? The results of the difference-in-difference analyses support rejecting the hypothesis. While lifting the cap does not significantly impact the relationship between charter school attendance and within-district segregation, the results do suggest that requiring charter schools to provide free and reduced-price lunch would reduce the percentage of hypersegregated schools within districts.

description: It is well known that the finite step-size ($h$) in Gradient Descent (GD) implicitly regularizes solutions to flatter minima. A natural question to ask is "Does the momentum parameter $β$ play a role in implicit regularization in Heavy-ball (H.B) momentum accelerated gradient descent (GD+M)?". To answer this question, first, we show that the discrete H.B momentum update (GD+M) follows a continuous trajectory induced by a modified loss, which consists of an original loss and an implicit regularizer. Then, we show that this implicit regularizer for (GD+M) is stronger than that of (GD) by factor of $(\frac{1+β}{1-β})$, thus explaining why (GD+M) shows better generalization performance and higher test accuracy than (GD). Furthermore, we extend our analysis to the stochastic version of gradient descent with momentum (SGD+M) and characterize the continuous trajectory of the update of (SGD+M) in a pointwise sense. We explore the implicit regularization in (SGD+M) and (GD+M) through a series of experiments validating our theory.

We discuss the $ Q^2 $ evolution of intrinsic quark distributions and present a code which provide these distributions as a function of $ x $ and $ Q^2 $ for any arbitrary Fock state probability. For the $ p\bar{p} $ collisions at the Tevatron, the results are compared with the recent experimental data of D0 at $\sqrt{s} =1.96$ TeV and also predictions for $ pp $ collisions at $\sqrt{s} =8$ TeV and $\sqrt{s} =13$ TeV for the LHC.

description: INTRODUCTION: The interest on 3D printing technology as a fabrication method has grown considerably across many disciplines. 3D printing has, in fact, found application in regenerative medicine as well as in the design of tissue models for personalised medicine, drug development and toxicological testing. The most common 3D printing technology is Fused Deposition Modelling (FDM) which employs a thermoplastic polymer as starting material that is extruded in sequential layers above its melting temperature to create a 3D object. Poly(lactic acid) is the most diffused thermoplastic polymer for FDM in biomedical applications. Other interesting materials are poly(ester-urethane)s (PUs), due to their high chemical versatility which can be exploited to synthesize a plethora of polymers matching the requirements of different applications. For instance, degradable PUs have been extensively studied in cardiac tissue engineering because of their elastomeric properties.
Dynamic Price Discrimination in Airline Markets Among Strategic Consumers

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This paper investigates the existence and effect that strategic consumers in airline markets have on overall consumer behavior when responding to dynamic pricing strategies. Using a series of large and detailed datasets on the transaction level, I estimate measures of consumer purchasing behavior and of price change dispersion using t-statistics, CDF estimation and k-means clustering. Using multiple regression on these measures, I show that the dispersion of price changes has a statistically significant effect on consumer purchasing behaviors. If prices increase as the date of departure approaches, the average consumer is more likely to purchase earlier. Conversely if prices decrease as the date of departure approaches, the average consumer is more likely to purchase later. Thus, at least some consumers exhibit strategic cost-minimizing behaviors using prior knowledge of the dispersion of price changes.

description: Gold surfaces host special electronic states that have been understood as a prototype of Shockley surface states (SSs). These SSs are commonly employed to benchmark the capability of angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling spectroscopy. We find that these Shockley SSs can be reinterpreted as topologically derived surface states (TDSSs) of a topological insulator (TI), a recently discovered quantum state. Based on band structure calculations, the Z2 topological invariant can be well defined to characterize the nontrivial features of gold that we detect by ARPES. The same TDSSs are also recognized on surfaces of other well-known noble metals (e.g., silver, copper, platinum, and palladium). Besides providing a new understanding of noble metal SSs, finding topological states on late transition metals provokes interesting questions on the role of topological effects in surface-related processes, such as adsorption and catalysis.

description: COLA is a software library for lattice QCD, written in a combination of modern Fortran and C/C++. Intel and NVIDIA have dominated the HPC domain in the years leading up to the exascale era, but the status quo has changed with the arrival of Frontier and other AMD-based systems in the supercomputing Top 500. Setonix is a next generation HPE Cray EX system hosted at the Pawsey Supercomputing Centre in Perth, Australia. Setonix features AMD EPYC CPUs and AMD Instinct GPUs. This report describes some of my experiences in evolving COLA to adapt to the current hardware landscape.

description: Quark confinement and dynamical chiral symmetry breaking are two of the most important emergent properties of the theory of quantum chromodynamics. We review recent results studying centre vortices in SU(3) lattice gauge theory with dynamical quarks. Through a vortex identification procedure, vortex-removed and vortex-only fields are obtained from the usual Monte Carlo generated gauge fields. Several comparisons between the untouched fields and the vortex-modified fields support the notion that centre vortices are fundamental to both confinement and dynamical chiral symmetry breaking in full QCD.

description: INTRODUCTION The risk a chemical poses to human health is a function of its potential to damage cells (toxicocynamics), coupled with the concentration to which cells are exposed in vivo (toxicokinetics) (Figure 1). Figure 1: The toxicokinetic and toxicodynamic processes that link between external exposure and adverse health outcomes Cell-based in vitro assays measure the former. The latter is dependent on the biokinetic properties of the chemical and often needs to be predicted using in silico mathematical models. Physiologically-based kinetic (PBK) models are important tools for simulating the toxicokinetics of a chemical compounds and predicting internal chemical concentrations at the organ, cellular and even subcellular levels for a given human exposure scenarios1. EXPERIMENTAL METHODS PBK models are in silico mathematical models that conceptualize the body as a system of interconnected compartments coupled by differential equations that describe the processes that govern the fate and transport of compounds between these compartments. Parameter values for these models are set a priori based on a combination of experimental data and theoretical knowledge of the compound, human anatomy and human physiology. RESULTS AND DISCUSSION PBK models for predicting chemical concentrations in cardiac tissue have been developed2. These can be adapted to account for the characteristics of different in vitro models, as well as the putative molecular targets and key events associated with the toxicodynamics of the chemical compound being studied. CONCLUSION PBK models are useful tools for predicting of time-concentrations profiles of chemicals in heart tissues to allow a meaningful interpretation of in vitro concentration-response data and predict in vivo outcomes.

description: A new measurement of the anomalous magnetic moment of the muon, $a_μ \equiv (g-2)/2$, will be performed at the Fermi National Accelerator Laboratory. The most recent measurement, performed at Brookhaven National Laboratory and completed in 2001, shows a 3.3-3.6 standard deviation discrepancy with the Standard Model predictions for $a_μ$. The new measurement will accumulate 21 times those statistics, measuring $a_μ$ to 140 ppb and reducing the uncertainty by a factor of 4. The data acquisition system for this experiment must have the ability to record deadtime-free records from 700 $μ$s muon spills at a raw data rate of 18 GB per second. Data will be collected using 1296 channels of $μ$TCA-based 800 MSPS, 12 bit waveform digitizers and processed in a layered array of networked commodity processors with 24 GPUs working in parallel to perform a fast recording and processing of detector signals during the spill. The system will be controlled using the MIDAS data acquisition software package. The described data acquisition system is currently being constructed, and will be fully operational before the start of the experiment in 2017.

On the Cooling and Freshening of Antarctic Intermediate Water in the South Pacific Ocean Between 1970 and 2018

description: Global warming is a driver of sometimes subtle shifts in climate patterns. One such area where subtle changes occur is deep ocean water formation, where alterations in processes regulating water density may impact surface conditions that determine water mass density (e.g., precipitation/evaporation, warming/cooling). The Antarctic Intermediate Water mass (AAIW) forms as an amalgamation of multiple water masses at the Antarctic Polar Front and spreads northward into all ocean basins. This feature of the AAIW makes it especially interesting for identifying how climate change impacts deep water formation, as the presence of the AAIW in all of the southern ocean basins allows scientists to use it as an early warning sign of climate change. Modern climatic processes, such as increased precipitation and rising surface ocean temperatures, influence the conservative temperature and salinity characteristics of the waters contributing to the volume of the AAIW, thus influence the characteristics of the AAIW itself. The AAIW should retain the signatures of temperature and salinity change at the time of its formation as it sinks and travels throughout the South Pacific Ocean during thermohaline circulation. In March and April of 2018, the expectation of preserved temperature and salinity change was tested aboard the Sea Education Association vessel SSV Robert C. Seamans. This senior honors thesis research sought to calculate rates of temperature and salinity change in the South Pacific AAIW from 1970 to 2018 on multiple time scales at both the upper boundary (700-800 m) and core (950-1050 m) of the water mass. CTD data collected during the six-week SEA cruise from Lyttelton, NZ, to Pape’ete, French Polynesia, were compared to historical cast data from the 2018 version of NOAA’s World Ocean Database to derive these temperature and salinity trends. For the sampled region of the South Pacific in my study, the AAIW was found to be experiencing freshening at both upper boundary and core depth zones, with increased freshening in the most recent ~20 years. Calculated temperature trends revealed that the AAIW is experiencing cooling at both depth zones in the most recent ~20 years, and decades-long cooling in its upper boundary zone. The freshening of the AAIW agrees with anthropogenically derived freshening trends in its Southern Ocean source waters, while the cooling trend could be a combination of modern sea surface warming influences and centuries-old remnants of cooling from past climatic events.

description: The goal of continual learning is to provide intelligent agents that are capable of learning continually a sequence of tasks using the knowledge obtained from previous tasks while performing well on prior tasks. However, a key challenge in this continual learning paradigm is catastrophic forgetting, namely adapting a model to new tasks often leads to severe performance degradation on prior tasks. Current memory-based approaches show their success in alleviating the catastrophic forgetting problem by replaying examples from past tasks when new tasks are learned. However, these methods are infeasible to transfer the structural knowledge from previous tasks i.e., similarities or dissimilarities between different instances. Furthermore, the learning bias between the current and prior tasks is also an urgent problem that should be solved. In this work, we propose a new method, named Online Continual Learning via the Knowledge Invariant and Spread-out Properties (OCLKISP), in which we constrain the evolution of the embedding features via Knowledge Invariant and Spread-out Properties (KISP). Thus, we can further transfer the inter-instance structural knowledge of previous tasks while alleviating the forgetting due to the learning bias. We empirically evaluate our proposed method on four popular benchmarks for continual learning: Split CIFAR 100, Split SVHN, Split CUB200 and Split Tiny-Image-Net. The experimental results show the efficacy of our proposed method compared to the state-of-the-art continual learning algorithms.

description: We propose a method of detecting a phase transition in a generalized Pólya urn in an information cascade experiment. The method is based on the asymptotic behavior of the correlation $C(t)$ between the first subject's choice and the $t+1$-th subject's choice, the limit value of which, $c\equiv \lim_{t\to \infty}C(t)$, is the order parameter of the phase transition. To verify the method, we perform a voting experiment using two-choice questions. An urn X is chosen at random from two urns A and B, which contain red and blue balls in different configurations. Subjects sequentially guess whether X is A or B using information about the prior subjects' choices and the color of a ball randomly drawn from X. The color tells the subject which is X with probability $q$. We set $q\in \{5/9,6/9,7/9,8/9\}$ by controlling the configurations of red and blue balls in A and B. The (average) lengths of the sequence of the subjects are 63, 63, 54.0, and 60.5 for $q\in \{5/9,6/9,7/9,8/9\}$, respectively. We describe the sequential voting process by a nonlinear Pólya urn model. The model suggests the possibility of a phase transition when $q$ changes. We show that $c>0\,\,\,(=0)$ for $q=5/9,6/9\,\,\,(7/9,8/9 )$ and detect the phase transition using the proposed method.
