ICASSP 20232023Dot-product attention is a core module in the present generation of neural network models, particularly transformers, and is being leveraged across numerous areas such as natural language processing and computer vision. This attention module is comprised of three linear transformations, namely query, key, and value linear transformations, each of which has a bias term. In this work, we study the role of

IntelliSys 20232023Over 80% of corporate value is now comprised of intangibles, of which a large component is human capability (HC). Reflecting this, the SEC has recently mandated HC reporting requirements (SEC, Q4 2020). We use machine learning to build a prototype system to analyze HC using SEC filings and applied it to 5,760 companies. The approach algorithmically generates lexicons for HC concepts, and then applies machine

AISTATS 20232023We propose the first boosting algorithm for offpolicy learning from logged bandit feedback. Unlike existing boosting methods for supervised learning, our algorithm directly optimizes an estimate of the policy’s expected reward. We analyze this algorithm and prove that the excess empirical risk decreases (possibly exponentially fast) with each round of boosting, provided a “weak” learning condition is satisfied

ICASSP 20232023We introduce a variant of the endpoint (EP) detection problem in automatic speech recognition (ASR), which we call the end-of-speech (EOS) estimation. Given an utterance, EOS estimation aims to identify the timestamp when the utterance waveform has fully decayed and is then used to measure the EP latency. Accurate EOS estimation is difficult in large-scale streaming audio scenarios due to the hefty traffic

ICRA 20232023This paper addresses the challenge of reconstructing a scene with a neural radiance field (NeRF) for robot vision and scene understanding using multiple modalities. Researchers have introduced the use of NeRF to represent an object for synthesizing and rendering novel views of complex scenes by optimizing a 3-D radiance field for ray casting and rendering for 2-D RGB images. However, using RGB images alone
