IMPROVING CAUSE DETECTION SYSTEMS WITH ACTIVE LEARNING

IMPROVING CAUSE DETECTION SYSTEMS WITH ACTIVE LEARNING
ISAAC PERSING AND VINCENT NG

Abstract. Active learning has been successfully applied to many natural language processing
tasks for obtaining annotated data in a cost-effective manner. We propose several extensions to an
active learner that adopts the margin-based uncertainty sampling framework. Experimental results
on a cause detection problem involving the classification of aviation safety reports demonstrate
the effectiveness of our extensions.

ER-2 X-band Radar (EXRAD) 3D Winds IMPACTS V1

The ER-2 X-band Radar (EXRAD) 3D Winds IMPACTS dataset consists of horizontal wind components, uncertainties in the horizontal wind components, and radar reflectivity collected by the EXRAD instrument onboard the NASA ER-2 aircraft. These data were gathered during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S Atlantic Coast (2020-2023, No deployments occurred in 2021 due to COVID-19). The campaign aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The EXRAD 3D Winds IMPACTS dataset files are available from January 25 through February 7, 2020 in netCDF-3 format.

OCO-3 Level 2 spatially ordered geolocated retrievals screened using the IMAP-DOAS Preprocessor (IDP), Forward Processing V11 (OCO3_L2_IMAPDOAS) at GES DISC

Version 11 is the current version of the data set. Older versions will no longer be available and are superseded by Version 11.

The Orbiting Carbon Observatory -3 (OCO-3) was deployed to the International Space Station in May, 2019. It is technically a single instrument, almost identical to OCO-2.

The Orbiting Carbon Observatory is the first NASA mission designed to collect space-based measurements of atmospheric carbon dioxide with the precision, resolution, and coverage needed to characterize the processes controlling its buildup in the atmosphere.

OCO-3 incorporates three high-resolution spectrometers that make coincident measurements of reflected sunlight in the near-infrared CO2 near 1.61 and 2.06 micrometers and in molecular oxygen (O2) A-Band at 0.76 micrometers. The three spectrometers have different characteristics and are calibrated independently. 

Oxygen-A Band cloud screening algorithm is one of the primary cloud screening tools implemented in the operational OCO processing pipeline. The algorithm was introduced and applied to early GOSAT data  with further analysis performed on OCO-2 simulations.

The OCO ABO2 algorithm employs a fast Bayesian retrieval to estimate surface pressure and surface albedo from high resolution spectra of the molecular oxygen (O2) A-band, near 0.765 µm. The radiative transfer forward model (FM) assumes a clear-sky condition, i.e. Rayleigh scattering only, such that differences between the modeled and measured radiances are apparent when the measurement scene contains cloud or aerosol.

Genesis Sample Catalog

The Genesis mission, launched in August 2001, collected solar wind at Earth-Sun L1 location for 28 months, and returned to Earth September 2004 with collectors (very pure materials with highly polished surfaces) into which solar wind atoms were implanted, typically 40 to 100 nm below the surface. The Genesis mission included three separate collections: high speed solar wind, coronal mass ejection solar wind and interstream low speed solar wind. Information from these different solar regimes is adding to the understanding of solar physics (figure 1). The catalog contains images, the material, the dimensions and area, the solar wind regime, and a qualitative assessment of surface condition. Cataloging is an ongoing process with more than 1850 samples characterized.

TRACKING CLIMATE MODELS

CLAIRE MONTELEONI*, GAVIN SCHMIDT**, AND SHAILESH SAROHA***

Climate models are complex mathematical models designed by meteorologists, geophysicists,
and climate scientists to simulate and predict climate. Given temperature predictions
from the top 20 climate models worldwide, and over 100 years of historical temperature data, we
track the changing sequence of which model currently predicts best. We use an algorithm due to
Monteleoni and Jaakkola that models the sequence of observations using a hierarchical learner,
based on a set of generalized Hidden Markov Models (HMM), where the identity of the current
best climate model is the hidden variable. The transition probabilities between climate models
are learned online, simultaneous to tracking the temperature predictions. On historical data, our
online learning algorithm’s average prediction loss nearly matches that of the best performing
climate model in hindsight. Moreover its performance surpasses that of the average model prediction,
which was the current state-of-the-art in climate science, the median prediction, and least
squares linear regression. We also experimented on climate model predictions through the year
2098. Simulating labels with the predictions of any one climate model, we found significantly improved
performance using our online learning algorithm with respect to the other climate models,
and techniques.

Designing Data-Driven Battery Prognostic Approaches for Variable Loading Profiles: Some Lessons Learned

Among various approaches for implementing prognostic algorithms data-driven algorithms are popular in the industry due to their intuitive nature and relatively fast developmental cycle. However, no matter how easy it may seem, there are several pitfalls that one must watch out for while developing a data-driven prognostic algorithm. One such pitfall is the uncertainty inherent in the system. At each processing step uncertainties get compounded and can grow beyond control in predictions if not carefully managed during the various steps of the algorithms. This paper presents analysis from our preliminary development of data- driven algorithm for predicting end of discharge of Li-ion batteries using constant load experiment data and challenges faced when applying these algorithms to randomized variable loading profile as is the case in realistic applications. Lessons learned during the development phase are presented.

Integrated LED/Imaging Illumination Panels Demonstrated within a Small Plant Growth Chamber Project

&lt;p&gt;&lt;strong&gt;LED light sources are ideal for plant growth systems. However, commercially available multi-color LED illumination panels are designed and manufactured to produce a single particular illumination. These panels have very specific LED colors arranged in a very specific fashion. This limits the amount of color mixing, intensity variation, and spatial arrangement that is possible, precluding passive precision illumination. There is no feedback mechanism to detect spectral shifts caused by LED aging and additionally, there is no mechanism to modulate LEDs. It is also not possible to integrate an imaging system into these panels. Furthermore, these panels are commonly operated using high voltage AC power sources, which is not ideal in a potentially wet environment. Therefore, to address these issues, custom LED illumination panels were designed and developed for this project&amp;rsquo;s plant growth chamber.&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;A systematic approach was taken to determine the general size, specifications, and shape of a portable plant growth unit. Once the general size and shape were finalized, the detailed design of the support structure, aeroponics, and lighting subsystems were developed. Particular attention was given to heat transfer and the expected LED thermal environment.&amp;nbsp; Additionally, a&amp;nbsp;&lt;/strong&gt;&lt;strong&gt;computational analysis was performed to determine optimal LED nodes placement so that two different uniform illumination fields could be yielded:&amp;nbsp; (1) for germinating plants, lower intensity light, and (2) for larger maturing plants, a brighter one.&amp;nbsp; Also, aeroponic studies were reviewed to identify an efficient and user-friendly system that would require minimal user involvement.&lt;/strong&gt;&lt;/p&gt;

Prognostics Health Management of Electronic Systems Under Mechanical Shock and Vibration Using Kalman Filter Models and Metrics

Structural damage to ball grid array interconnects incurred during vibration testing has been monitored in the prefailure space using resistance spectroscopy-based state space vectors, rate of change of the state variable, and acceleration of the state variable. The technique is intended for condition monitoring in high reliability applications where the knowledge of impending failure is critical and the risks in terms of loss of functionality are too high to bear. Future state of the system has been estimated based on a second-order Kalman Filter model and a Bayesian Framework. The measured state variable has been related to the underlying interconnect damage in the form of inelastic strain energy density. Performance of the prognostic health management algorithm during the vibration test has been quantified using performance evaluation metrics. The method- ology has been demonstrated on leadfree area-array electronic assemblies subjected to vibration. Model predictions have been correlated with experimental data. The presented approach is applicable to functional systems where corner interconnects in area-array packages may be often redundant. Prognostic metrics including α − λ precision, β accuracy, and relative accuracy have been used to assess the performance of the damage proxies. The presented approach enables the estimation of residual life based on level of risk averseness.
