AISTATS 20202019We study the problem of offline learning in automated decision systems under the contextual bandits model. We are given logged historical data consisting of contexts, (randomized) actions, and (nonnegative) rewards. A common goal is to evaluate what would happen if different actions were taken in the same contexts, so as to optimize the action policies accordingly. The typical approach to this problem,

Interspeech 20192019Acoustic Event Detection (AED), aiming at detecting categories of events based on audio signals, has found application in many intelligent systems. Recently deep neural network significantly advances this field and reduces detection errors to a large scale. However how to efficiently execute deep models in AED has received much less attention. Meanwhile state-of-the-art AED models are based on large deep

CVPR 2019 Robotic Vision Probabilistic Object Detection Challenge2019Vision is an integral part of many robotic systems, and especially so when a robot must interact with its environment. In such cases, decisions made based on erroneous visual detections can have disastrous consequences. Hence, being able to accurately measure the uncertainty associated with visual information is highly important for making informed decisions. However, this uncertainty is often not captured

Interspeech 20192019We present a hybrid approach for scaling distributed training of neural networks by combining Gradient Threshold Com-pression (GTC) algorithm - a variant of stochastic gradient de-scent (SGD) - which compresses gradients with thresholding and quantization techniques and Blockwise Model Update Filtering(BMUF) algorithm - a variant of model averaging (MA). In this proposed method we divide total number of

ICCV 2019 Workshop on Computer Vision for Fashion, Art and Design2019The emergence of online influencers, the explosion of video content, and the massive amount of movie collections have served as an advertising vehicle for the fashion industry. This trend has created the need for automated methods that recognize people’s outfit in such image and video collections. However, existing computer vision solutions for fashion recognition require an enormous amount of labeled data
