New Energy-Momentum and Angular Momentum Tensors with Applications to Nucleon Structure

2017 · ArXiv.org

We present a new type of energy-momentum tensor and angular momentum tensor. They are motivated by a special consideration in quantum measurement: Given a wave in mutual eigen-state of more than one physical observables, the …

Simple Recurrence Improves Masked Language Models

2022 · arXiv (Cornell University)

In this work, we explore whether modeling recurrence into the Transformer architecture can both be beneficial and efficient, by building an extremely simple recurrent module into the Transformer. We compare our model to baselines following …

Multi-Vector Retrieval as Sparse Alignment

2022 · arXiv (Cornell University)

Multi-vector retrieval models improve over single-vector dual encoders on many information retrieval tasks. In this paper, we cast the multi-vector retrieval problem as sparse alignment between query and document tokens. We propose AligneR, a novel …
