CNNBiF: CNN-based Bigram Features for Named Entity Recognition

no code implementations Findings (EMNLP) 2021 Chul Sung, Vaibhava Goel, Etienne Marcheret, Steven Rennie, David Nahamoo

More importantly our fine-tuned CoNLL2003 model displays significant gains in generalization to out of domain datasets: on the OntoNotes subset we achieve an F1 of 72. 67 which is 0. 49 points absolute better than the baseline, and on the WNUT16 set an F1 of 68. 22 which is a gain of 0. 48 points.

Unsupervised Adaptation of Question Answering Systems via Generative Self-training

no code implementations EMNLP 2020 Steven Rennie, Etienne Marcheret, Neil Mallinar, David Nahamoo, Vaibhava Goel

Nevertheless, additional pre-training closer to the end-task, such as training on synthetic QA pairs, has been shown to improve performance.

McGan: Mean and Covariance Feature Matching GAN

no code implementations ICML 2017 Youssef Mroueh, Tom Sercu, Vaibhava Goel

We introduce new families of Integral Probability Metrics (IPM) for training Generative Adversarial Networks (GAN).

Self-critical Sequence Training for Image Captioning

31 code implementations CVPR 2017 Steven J. Rennie, Etienne Marcheret, Youssef Mroueh, Jarret Ross, Vaibhava Goel

In this paper we consider the problem of optimizing image captioning systems using reinforcement learning, and show that by carefully optimizing our systems using the test metrics of the MSCOCO task, significant gains in performance can be realized.

Random Maxout Features

no code implementations11 Jun 2015 Youssef Mroueh, Steven Rennie, Vaibhava Goel

In this paper, we propose and study random maxout features, which are constructed by first projecting the input data onto sets of randomly generated vectors with Gaussian elements, and then outputing the maximum projection value for each set.
