Zero-shot sampling of adversarial entities in biomedical question answering

no code implementations16 Feb 2024 R. Patrick Xian, Alex J. Lee, Vincent Wang, Qiming Cui, Russell Ro, Reza Abbasi-Asl

Our investigations illustrate the brittleness of domain knowledge in LLMs and reveal a shortcoming of standard evaluations for high-capacity models.

Question Answering

Machine Learning for Uncovering Biological Insights in Spatial Transcriptomics Data

no code implementations29 Mar 2023 Alex J. Lee, Robert Cahill, Reza Abbasi-Asl

Development and homeostasis in multicellular systems both require exquisite control over spatial molecular pattern formation and maintenance.

Multi-Modal Prototype Learning for Interpretable Multivariable Time Series Classification

no code implementations17 Jun 2021 Gaurav R. Ghosal, Reza Abbasi-Asl

We validate our framework on a simulated dataset with embedded patterns, as well as a real human activity recognition problem.

Interpreting Convolutional Neural Networks Through Compression

no code implementations7 Nov 2017 Reza Abbasi-Asl, Bin Yu

In our compression, the filter importance index is defined as the classification accuracy reduction (CAR) of the network after pruning that filter.

Structural Compression of Convolutional Neural Networks

no code implementations20 May 2017 Reza Abbasi-Asl, Bin Yu

Deep convolutional neural networks (CNNs) have been successful in many tasks in machine vision, however, millions of weights in the form of thousands of convolutional filters in CNNs makes them difficult for human intepretation or understanding in science.
