ICASSP 20232023Self-supervised representation learning approaches have grown in popularity due to the ability to train models on large amounts of unlabeled data and have demonstrated success in diverse fields such as natural language processing, computer vision, and speech. Previous self-supervised work in the speech domain has disentangled multiple attributes of speech such as linguistic content, speaker identity, and

GrAPL 20232023GNN models on heterogeneous graphs have achieved state-of-the-art (SOTA) performance in various graph tasks such as link prediction and node classification. Despite their success in providing SOTA results, popular GNN libraries, such as PyG and DGL, fail to provide fast and efficient solutions for heterogeneous GNN models. One common key bottlenecks of models like RGAT, RGCN, and HGT is relation-specific

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
