Using i-vectors for subject-independent cross-session EEG transfer learning

no code implementations16 Jan 2024 Jonathan Lasko, Jeff Ma, Mike Nicoletti, Jonathan Sussman-Fort, Sooyoung Jeong, William Hartmann

Cognitive load classification is the task of automatically determining an individual's utilization of working memory resources during performance of a task based on physiologic measures such as electroencephalography (EEG).

Overcoming Domain Mismatch in Low Resource Sequence-to-Sequence ASR Models using Hybrid Generated Pseudotranscripts

no code implementations14 Jun 2021 Chak-Fai Li, Francis Keith, William Hartmann, Matthew Snover, Owen Kimball

We show that there is a sizable initial gap in such a data condition between hybrid and seq2seq models, and the hybrid model is able to further improve through the use of additional language model (LM) data.

The 2019 BBN Cross-lingual Information Retrieval System

no code implementations LREC 2020 Le Zhang, Damianos Karakos, William Hartmann, Manaj Srivastava, Lee Tarlin, David Akodes, Sanjay Krishna Gouda, Numra Bathool, Lingjun Zhao, Zhuolin Jiang, Richard Schwartz, John Makhoul

In this paper, we describe a cross-lingual information retrieval (CLIR) system that, given a query in English, and a set of audio and text documents in a foreign language, can return a scored list of relevant documents, and present findings in a summary form in English.

Reformulating Information Retrieval from Speech and Text as a Detection Problem

no code implementations LREC 2020 Damianos Karakos, Rabih Zbib, William Hartmann, Richard Schwartz, John Makhoul

In the IARPA MATERIAL program, information retrieval (IR) is treated as a hard detection problem; the system has to output a single global ranking over all queries, and apply a hard threshold on this global list to come up with all the hypothesized relevant documents.

Learning from Noisy Labels with Noise Modeling Network

no code implementations1 May 2020 Zhuolin Jiang, Jan Silovsky, Man-Hung Siu, William Hartmann, Herbert Gish, Sancar Adali

Multi-label image classification has generated significant interest in recent years and the performance of such systems often suffers from the not so infrequent occurrence of incorrect or missing labels in the training data.

Cross-lingual Information Retrieval with BERT

1 code implementation LREC 2020 Zhuolin Jiang, Amro El-Jaroudi, William Hartmann, Damianos Karakos, Lingjun Zhao

Multiple neural language models have been developed recently, e. g., BERT and XLNet, and achieved impressive results in various NLP tasks including sentence classification, question answering and document ranking.

Towards a New Understanding of the Training of Neural Networks with Mislabeled Training Data

no code implementations18 Sep 2019 Herbert Gish, Jan Silovsky, Man-Ling Sung, Man-Hung Siu, William Hartmann, Zhuolin Jiang

This includes results about the ability of the noisy model to make the same decisions as the clean model and the effects of noise on model performance.
