Classification and Representation via Separable Subspaces: Performance Limits and Algorithms

no code implementations7 May 2017 Ishan Jindal, Matthew Nokleby

We study the classification performance of Kronecker-structured models in two asymptotic regimes and developed an algorithm for separable, fast and compact K-S dictionary learning for better classification and representation of multidimensional signals by exploiting the structure in the signal.

Learning Deep Networks from Noisy Labels with Dropout Regularization

no code implementations9 May 2017 Ishan Jindal, Matthew Nokleby, Xue-wen Chen

Large datasets often have unreliable labels-such as those obtained from Amazon's Mechanical Turk or social media platforms-and classifiers trained on mislabeled datasets often exhibit poor performance.

A Unified Neural Network Approach for Estimating Travel Time and Distance for a Taxi Trip

no code implementations12 Oct 2017 Ishan Jindal, Tony, Qin, Xue-wen Chen, Matthew Nokleby, Jieping Ye

In building intelligent transportation systems such as taxi or rideshare services, accurate prediction of travel time and distance is crucial for customer experience and resource management.

Tensor Matched Kronecker-Structured Subspace Detection for Missing Information

no code implementations25 Oct 2018 Ishan Jindal, Matthew Nokleby

We consider the problem of detecting whether a tensor signal having many missing entities lies within a given low dimensional Kronecker-Structured (KS) subspace.

Optimizing Taxi Carpool Policies via Reinforcement Learning and Spatio-Temporal Mining

no code implementations11 Nov 2018 Ishan Jindal, Zhiwei Qin, Xue-wen Chen, Matthew Nokleby, Jieping Ye

In this paper, we develop a reinforcement learning (RL) based system to learn an effective policy for carpooling that maximizes transportation efficiency so that fewer cars are required to fulfill the given amount of trip demand.

CLAR: A Cross-Lingual Argument Regularizer for Semantic Role Labeling

no code implementations Findings of the Association for Computational Linguistics 2020 Ishan Jindal, Yunyao Li, Siddhartha Brahma, Huaiyu Zhu

Although different languages have different argument annotations, polyglot training, the idea of training one model on multiple languages, has previously been shown to outperform monolingual baselines, especially for low resource languages.
