Data-Informed Global Sparseness in Attention Mechanisms for Deep Neural Networks

COLING 2024main

Attention mechanisms play a crucial role in the neural revolution of Natural Language Processing (NLP). With the growth of attention-based models, several pruning techniques have been developed to identify and exploit sparseness, making these models more efficient. Most efforts focus on hard-coding…

OccamLLM: Fast and Exact Language Model Arithmetic in a Single Step

NeurIPS 2024poster

Despite significant advancements in text generation and reasoning, Large Language Models (LLMs) still face challenges in accurately performing complex arithmetic operations. Language model systems often enable LLMs to generate code for arithmetic operations to achieve accurate calculations. However,…

Multi-Symmetry Ensembles: Improving Diversity and Generalization via Opposing Symmetries

ICML 2023poster

Deep ensembles (DE) have been successful in improving model performance by learning diverse members via the stochasticity of random initialization. While recent works have attempted to promote further diversity in DE via hyperparameters or regularizing loss functions, these methods primarily still r…

Q-Flow: Generative Modeling for Differential Equations of Open Quantum Dynamics with Normalizing Flows

ICML 2023poster

Studying the dynamics of open quantum systems can enable breakthroughs both in fundamental physics and applications to quantum engineering and quantum computation. Since the density matrix $\rho$, which is the fundamental description for the dynamics of such systems, is high-dimensional, customized…

QuACK: Accelerating Gradient-Based Quantum Optimization with Koopman Operator Learning

NeurIPS 2023spotlight

Quantum optimization, a key application of quantum computing, has traditionally been stymied by the linearly increasing complexity of gradient calculations with an increasing number of parameters. This work bridges the gap between Koopman operator theory, which has found utility in applications beca…

DiffCSE: Difference-based Contrastive Learning for Sentence Embeddings

NAACL 2022long

We propose DiffCSE, an unsupervised contrastive learning framework for learning sentence embeddings. DiffCSE learns sentence embeddings that are sensitive to the difference between the original sentence and an edited sentence, where the edited sentence is obtained by stochastically masking out the o…

Equivariant Self-Supervised Learning: Encouraging Equivariance in Representations

ICLR 2022poster

In state-of-the-art self-supervised learning (SSL) pre-training produces semantically good representations by encouraging them to be invariant under meaningful transformations prescribed from human knowledge. In fact, the property of invariance is a trivial instance of a broader class called equivar…

We Can Explain Your Research in Layman’s Terms: Towards Automating Science Journalism at Scale

AAAI 2021technical

We propose to study Automating Science Journalism (ASJ), the process of producing a layman's terms summary of a research article, as a new benchmark for long neural abstractive summarization and story generation. Automating science journalism is a challenging task as it requires paraphrasing complex…
