SF-QA: Simple and Fair Evaluation Library for Open-domain Question Answering

2021 · arXiv (Cornell University)

Although open-domain question answering (QA) draws great attention in recent years, it requires large amounts of resources for building the full system and is often difficult to reproduce previous results due to complex configurations. In …

How to Evaluate the Generalization of Detection? A Benchmark for Comprehensive Open-Vocabulary Detection

2024 · Proceedings of the AAAI Conference on Artificial Intelligence

Object detection (OD) in computer vision has made significant progress in recent years, transitioning from closed-set labels to open-vocabulary detection (OVD) based on large-scale vision-language pre-training (VLP). However, current evaluation methods and datasets are limited …

Learning Discourse-level Diversity for Neural Dialog Models using Conditional Variational Autoencoders

2017

While recent neural encoder-decoder models have shown great promise in modeling open-domain conversations, they often generate dull and generic responses. Unlike past work that has focused on diversifying the output of the decoder at word-level …
