Deep Learning Driven Venue Recommender for Event-Based Social Networks

Event-based online social platforms, such as Meetup and Plancast, have experienced increased popularity and rapid growth in recent years. In EBSN setup, selecting suitable venues for hosting events, which can attract a great turnout, is a key challenge. In this paper, we present a deep learning based venue recommendation system <inline-formula><tex-math notation="LaTeX">$DeepVenue$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>D</mml:mi><mml:mi>e</mml:mi><mml:mi>e</mml:mi><mml:mi>p</mml:mi><mml:mi>V</mml:mi><mml:mi>e</mml:mi><mml:mi>n</mml:mi><mml:mi>u</mml:mi><mml:mi>e</mml:mi></mml:mrow></mml:math><inline-graphic xlink:href="pramanik-ieq1-2915523.gif"/></alternatives></inline-formula> which provides context driven venue recommendations for the <italic>Meetup event-hosts</italic> to host their events. The crux of the proposed model relies on the notion of similarity between multiple Meetup entities such as events, venues, groups, etc. We develop deep learning techniques to compute a compact descriptor for each entity, such that two entities (say, venues) can be compared numerically. Notably, to mitigate the scarcity of venue related information in Meetup, we leverage on the cross domain knowledge transfer from popular LBSN service Yelp to extract rich venue related content. For hosting an event, the proposed <inline-formula><tex-math notation="LaTeX">$DeepVenue$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>D</mml:mi><mml:mi>e</mml:mi><mml:mi>e</mml:mi><mml:mi>p</mml:mi><mml:mi>V</mml:mi><mml:mi>e</mml:mi><mml:mi>n</mml:mi><mml:mi>u</mml:mi><mml:mi>e</mml:mi></mml:mrow></mml:math><inline-graphic xlink:href="pramanik-ieq2-2915523.gif"/></alternatives></inline-formula> model computes a success score for each candidate venue and ranks those venues according to the scores and finally recommend the top k venues. Our rigorous evaluation on the Meetup data collected for the city of Chicago shows that <inline-formula><tex-math notation="LaTeX">$DeepVenue$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>D</mml:mi><mml:mi>e</mml:mi><mml:mi>e</mml:mi><mml:mi>p</mml:mi><mml:mi>V</mml:mi><mml:mi>e</mml:mi><mml:mi>n</mml:mi><mml:mi>u</mml:mi><mml:mi>e</mml:mi></mml:mrow></mml:math><inline-graphic xlink:href="pramanik-ieq3-2915523.gif"/></alternatives></inline-formula> significantly outperforms the baselines algorithms.

A Resilient Transparent Optical Network Design with a Pre-Configured Extended-Tree Scheme

We propose a new design scheme of resilient Wavelength Division Multiplexing (WDM) networks by extending and reshaping pre-configured protection tree (p-tree) structures. The resulting protection scheme relies on optimized pre-cross connected structures that span all previously proposed protection patterns. p-Tree-based protection schemes offer the advantages of scalability, local restoration capabilities, and failure impact restriction, but at the same time suffer from capacity inefficiency. While keeping these advantages, we propose an extension (reshaping) of the p-tree protection pattern that imposes no restriction on the shapes of the protection building blocks. Not only the resulting protection scheme remains scalable and highly flexible, but it also leads to pre-configured protection structures that improve much further on capacity efficiency and recovery delay. We establish some new integer linear programming models, and use a large scale optimization tool, named column generation (CG) to solve them. Our CG-based solution method is highly scalable as it does not require an a priori explicit enumeration of the protection structures, but an efficient dynamic enumeration of only the most promising ones. Comparison are made with three other protection schemes, i.e, simple and non-simple p-cycles (fully pre-cross connected structures) as well as p-trees. Results show a clear advantage of the proposed extended-tree scheme with respect to flexibility, capacity efficiency, and restoration delay.
QoS improvements for MCU-ru

MCU-ru is a popular video conference system, improved from Multipoint Control Unit (MCU) open source. Users can send their video streams to MCU server and the system compresses all received video streams into one mixed multiple-view stream and sends back to all users. This method allows users with modest Internet bandwidth to video conference. Although the system works well in many countries, the quality of video conferencing can be significantly reduced when the available bandwidth is not stable, such as peak usage times. This article focuses on the improvement of the problem mentioned above by a simple approach: for a chosen codec when a client receives the mixed stream from MCU server by RTP, RTCP sends the quality feedback of the communication session to MCU server as well as in the reverse direction. As a result, both the client and server would have enough information to adjust the frame-per-second (FPS) and video resolution to optimize the usage of the available network bandwidth. We have run the system through multiple test scenarios and found that this method shows promising results in reducing bandwidth consumption. Lastly, an added feature of the design allows users to switch between mixed stream and specific stream, which gives participants of the video conferences more options.

Conclusion: Numerous opportunities exist for clinical and consulting practitioners to intervene to improve the current management of workplace depression.
The evaluation of CRM systems: a behaviors-based conceptual framework

Research-in-progress on the evaluation of mandatory Customer Relationship Management Information Systems (CRM IS) is presented. The business problem is presented, followed by converging theoretical considerations, which assist in making the case for a wider conceptualisation of CRM evaluation which values a social perspective of CRM IS use at boundary-spanning professional (BSP) and customer levels. An emotions based conceptual framework for use in evaluating CRM IS from this social perspective is then presented, building on a theory of emotional expression. The framework is explained and then discussed in terms of how the framework can be applied and data outputs analysed in a field analysis context. The broader research programme aims to test and validate the model according to the details given and through doing so, further understanding of the impact of CRM IS from this behaviours based, social perspective.
Hemodynamic Changes in a Term Newborn Piglet Model of Patent Ductus Arteriosus

Patent ductus arteriosus (PDA) is a common form of congenital heart disease in full-term infants. To investigate the morbidities associated with a left to right PDA shunt, we produced a PDA in six full-term newborn piglets (less than 36 hours old) by bathing the ductus arteriosus with prostaglandin E (PGE) and infiltrating it with formalin. In five age-matched piglets, the ductus arteriosus was ligated to serve as controls. Microsphere determinations of left ventricular output (LVO) and regional blood flow (Q) were made on three consecutive days. We produced left to right shunts of 36 to 47% (mean) in the experimental piglets. The experimental piglets had a 22 to 36% increase in LVO with a one- to twofold reduction in percentage of LVO to the kidneys and carcass (p less than 0.05). Although percentage of LVO to the gastrointestinal tract was reduced (p less than 0.05), no reduction of absolute Q to the gastrointestinal tract was observed. Brain and heart Q were similar in both groups. We conclude that significant hemodynamic changes result from left to right shunting in the full-term newborn piglet with PDA. These hemodynamic changes, such as reduction in renal blood flow, are relevant information that will help explain the morbidities observed in infants with a hemodynamically significant PDA with a left to right shunt.
Relationship Suicide, Cognitive Functions, and Depression in Patients with Schizophrenia.

INTRODUCTION The aim of this study was to compare schizophrenic patients with and without a suicide attempt history in terms of sociodemographic and clinical features and cognitive functions and to determine the predictive factors for suicide attempt history. METHODS In this study, we assessed and compared 70 patients with schizophrenia, 27 patients with a suicide attempt history, and 43 patients without a suicide attempt history. The cognitive functions of patients were assessed by the Stroop test, Wisconsin Card Sorting Test (WCST), and Rey Auditory Verbal Learning Test. In order to evaluate clinical symptoms, the Positive and Negative Syndrome Scale (PANSS) and Calgary Depression Scale for Schizophrenia (CDSS) were used. RESULTS In this study, the number of hospitalizations, PANSS general psychopathology subscale score, CDSS total score, suicide item score, and WCST total number of responses (WCST1) were significantly higher among the patients with a suicide attempt history. The WCST1 and CDSS total scores were predicted using the suicide attempt history. CONCLUSION Revealing the factors related to suicidal behavior in patients with schizophrenia contributes to the prevention of suicide. Studies with long-term follow-up and with a larger sample group are required for the investigation of relationship suicide, cognitive impairment, which is one of the core symptoms of schizophrenia, and depression.
Gaitspert: An Expert System for the Evaluation of Abnormal Human Locomotion Arising from Stroke

This paper describes the implementation and use of a knowledge-based system for the evaluation of abnormal human locomotion arising from cerebral vascular accidents (CVA). An expert system (GAITSPERT) that is knowledgeable about the evaluation of human gait has been implemented primarily as a clinical tool that can produce assessments of underlying stroke disease states and recommendations about therapeutic interventions. GAITSPERT combines artificial intelligence (AI) analysis methodologies with biomedical signal acquisition and evaluation providing intelligent processing of kinematic, electromyographic (EMG), and foot-switch data. GAITSPERT was constructed using GENIE, a general-purpose knowledge-enginering tool, and a knowledge base of stroke-related facts about neuromuscular disabilities.
A Brief Note on Implementing Boundary Conditions at a Solid Wall Using the FCT Algorithm

Abstract : The implementation of boundary conditions at a solid wall using the flux-corrected transport (FCT) algorithm has been studied. We found that extrapolating the interior points to obtain the pressure at the wall may introduce instability. Instead, the given physical conditions at the wall, such as the continuity equation and the given thermal conditions, should he used to evaluate the pressure at the wall. Since the viscous diffusion and other source terms can be calculated from flow variables at interior points and the wall surface, the need to specify the guard-cell values at a solid wall is only required by the numerical diffusion embedded in FCT. Guard-cell values may interfere with the activation of the flux limiter near the wall, introducing either numerical instability or producing unphysical numerical results. Several approaches have been proposed to control this interference, such as turning off numerical diffusion at the first cell near the wall, or introducing extra numerical diffusion in the momentum equation at the wall to suppress the instability.
Multi-chain time interval measurement method utilizing the dedicated carry chain of FPGA

In this paper, we propose a high accuracy multi-chain time interval measurement (TIM) technique by employing the dedicated carry chain of FPGA. According to the principle of delay chain time to digital converter (TDC), the proposed method is realized by connecting the selectors inside the slices. The resolution of the delay chain method is limited by the time delay of one delay unit. To break through the resolution bottleneck of the delay chain approach, a TIM structure is adopted by utilizing the dedicated carry chain of FPGA. To verify the proposed method, we implement a multi-chain TIM circuit which consists of 16 chains in the Kintex-7 filed-programmable-gate arrays (FPGA). The post-route simulation results show that the bine size can be increased to 1.67ps and the RMS is enhanced to 3.99ps without bringing extra dead time. In addition, the proposed method is able to make full use of the delay unit, which reduces the hardware cost of the circuit by nearly 35% compared to the previous method.
Vascular Risk Factors and Dementia: 40-Year Follow-Up of a Population-Based Cohort

Aims: Our aim was to evaluate the longitudinal associations of individual and multiple vascular risk factors with the subsequent development of dementia and Alzheimer’s disease (AD). Methods: The Uppsala Longitudinal Study of Adult Men started in 1970 when the 2,268 participants were 50 years old. Baseline investigations included determinations of blood pressure, fasting glucose, cholesterol, BMI and smoking status. Over a maximum follow-up of 40 years, 349 participants were diagnosed with dementia, out of which 127 had AD. Analyses were repeated using a re-examination of the cohort at 70 years of age as a baseline. Results: No associations between vascular risk factors and AD were found. For all-type dementia, the association between high systolic blood pressure and dementia was the most consistent. High fasting glucose was associated with increased risk of all-type dementia only when measured at 70 years. Individuals with both an APOE Ε4 allele and vascular risk factors had the greatest dementia risk. Conclusion: Vascular risk factors influence the future risk of dementia, in particular vascular and mixed-type rather than AD. The impact of vascular risk factors on dementia in a longitudinal study depends on the age at baseline and the length of follow-up.
Importance of the Anatomic Features of the Lacrimal Artery for Orbital Approaches

Knowledge of variations in the possible patterns of origin, course, and distribution of the lacrimal artery are necessary for the diagnosis and important for the treatment of orbital disorders. The vascularization of 38 lacrimal glands was studied by orbital dissection subsequent to injection of the arterial bed with red-dyed latex. The origin, calibration, and branches of the lacrimal artery and its topographic relations were investigated.In all subjects, arteria lacrimalis originated from ophthalmic artery. On the right, the lacrimal artery sprang from the angle of the ophthalmic artery in 63.15% of the cases, from the curve of the ophthalmic artery in 26.31%, and from the first part the ophthalmic artery in 5.26%. The outer diameter of the lacrimal artery was measured as 1.02 ± 0.17 mm on the right and 1.03 ± 0.16 mm on the left. In 68.42 of the cases on the right and in 52.63 of the cases on the left, the lacrimal artery was present, and the lacrimal nerve was seen in a superolateral position with respect to the origin of the artery. Variability of the glandular branch in its course toward lacrimal gland was observed. Recurrent meningeal branch was seen in six cases on the right and in five on the left. On the right, of the six cases, two passed through meningoorbital foramen, and four passed through superior orbital fissure and entered middle cranial fossa. On the left, of the five cases, two passed through meningoorbital foramen, and three passed through superior orbital fissure and entered middle cranial fossa. In this case, the lacrimal gland is the site of an intraorbital anastomosis between internal and external carotid systems.This article confirms the well-known variability of the lacrimal arterial branches and their relation to the lacrimal gland. These variations have been discussed and described with respect to the embryonic development. A better understanding of the vascular anatomy of the lacrimal gland should allow modification of surgical techniques to reduce bleeding during biopsy or excision of the lacrimal gland.
Attribute learning for ship category recognition in remote sensing imagery

Object category recognition, in remote sensing imagery, usually relies on exemplar-based training. The latter is achieved by modeling intricate relationships between object categories and visual features. However, for real-world and fine grained object categories - exhibiting complex visual appearance and strong variability - these models may fail especially when training data are scarce. In this paper, we introduce an effective object category recognition approach that alleviates the limitation caused by small training sets. The method learns discriminant mid-level representations (a.k.a. attributes) through nonlinear mappings that make these attributes highly discriminant while being easily trainable and predictable. We demonstrate the effectiveness of our method, through extensive experiments on the challenging task of ship recognition in maritime environments, and we show how our attribute learning model generalizes well in spite of the scarcity of training data.
Candidate Faces and Election Outcomes ∗

Recent research finds that naive survey participants’ rapid evaluations of the facial competence of United States Congressional candidates predict aggregate vote margins. The predictive power of facial competence has generated considerable interest because it seems to indicate a causal relationship between face and vote choice. Because there is no a priori reason to expect that candidate facial qualities are randomly distributed across electoral contests, we estimate the effect of facial competence using multiple regression analysis with controls. Using data from a survey we implemented with evaluations of more than 167,000 pairs of candidate faces, we find evidence that facial competence has a small but significant causal effect on vote choice; we also find evidence that candidates with high facial competence participate in the most competitive electoral contests. We argue that faces are an interactive part of a bigger political story that structures election results. ∗The authors thank Mike Franks, Gary Jacobson, R.

A machine learning method for generation of a neural network architecture: a continuous ID3 algorithm

The relation between the decision trees generated by a machine learning algorithm and the hidden layers of a neural network is described. A continuous ID3 algorithm is proposed that converts decision trees into hidden layers. The algorithm allows self-generation of a feedforward neural network architecture. In addition, it allows interpretation of the knowledge embedded in the generated connections and weights. A fast simulated annealing strategy, known as Cauchy training, is incorporated into the algorithm to escape from local minima. The performance of the algorithm is analyzed on spiral data.
COUNTERGRADIENT VARIATION AND SECONDARY SEXUAL COLOR: PHENOTYPIC CONVERGENCE PROMOTES GENETIC DIVERGENCE IN CAROTENOID USE BETWEEN SYMPATRIC ANADROMOUS AND NONANADROMOUS MORPHS OF SOCKEYE SALMON (ONCORHYNCHUS NERKA)

Abstract Genetically distinct anadromous (sockeye) and nonanadromous (kokanee) morphs of the Pacific salmon, Oncorhynchus nerka, develop identical, brilliant red color at maturity during sympatric breeding in freshwater streams. The marine and lacustrine environments they occupy prior to maturity, however, appear to differ in the availability of dietary carotenoid pigments necessary to produce red coloration. We tested the hypothesis that kokanee, which occupy carotenoid-poor lakes, are more efficient at using the dietary pigments than are sockeye, which occupy the more productive North Pacific Ocean. In a 2-year controlled breeding study, flesh and skin color of mature and immature crosses fed a low-carotenoid diet were quantified with both a chromameter and by chemical extraction of carotenoid pigments. Results revealed striking countergradient variation in carotenoid use, with kokanee approximately three times more efficient at sequestering the pigments to the flesh musculature than similar age sockeye. This difference translated into virtually nonoverlapping differences between pure crosses in secondary sexual color at maturity, when the pigments are mobilized and transported to the skin. Kokanee crosses turned pinkish red over most of their body, whereas sockeye turned olive green. The olive green was similar to the breeding color of residuals in the wild, the progeny of anadromous sockeye that remain in fresh water and are believed to have given rise to kokanee on numerous independent occasions. Reciprocal hybrids were similar to each other and intermediate to the pure crosses, indicating additive genetic inheritance. Mate choice trials with sockeye males in the wild showed the ancestral morph strongly preferred red over green models. These results suggest a preference for red mates maintained in nonanadromous breeding populations drove the reevolution of the red phenotype in kokanee via more efficient use of dietary carotenoid pigments. This is a novel, yet hidden, mechanism by which sexual selection promotes the genetic differentiation of these sympatric populations.
