Rate of convergence for data augmentation and inverse Bayes formula method in the genetic linkage model

2017

Many statistical problems can be formulated as the missing data problems. The data augmentation algorithm and the inverse Bayes formula are important tools for constructing iterative optimization or samplings via the introduction of unobserved data …

SimCSE++: Improving Contrastive Learning for Sentence Embeddings from Two Perspectives

2023 · arXiv (Cornell University)

This paper improves contrastive learning for sentence embeddings from two perspectives: handling dropout noise and addressing feature corruption. Specifically, for the first perspective, we identify that the dropout noise from negative pairs affects the model's …

Elevating Software Trust: Unveiling and Quantifying the Risk Landscape

2024 · arXiv (Cornell University)

Considering the ever-evolving threat landscape and rapid changes in software development, we propose a risk assessment framework called SAFER (Software Analysis Framework for Evaluating Risk). This framework is based on the necessity of a dynamic, …
