EEG-GPT: Exploring Capabilities of Large Language Models for EEG Classification and Interpretation

no code implementations31 Jan 2024 Jonathan W. Kim, Ahmed Alaa, Danilo Bernardo

In conventional machine learning (ML) approaches applied to electroencephalography (EEG), this is often a limited focus, isolating specific brain activities occurring across disparate temporal scales (from transient spikes in milliseconds to seizures lasting minutes) and spatial scales (from localized high-frequency oscillations to global sleep activity).

Generating Drug Repurposing Hypotheses through the Combination of Disease-Specific Hypergraphs

no code implementations16 Nov 2023 Ayush Jain, Marie Laure-Charpignon, Irene Y. Chen, Anthony Philippakis, Ahmed Alaa

Cosine similarity values are computed between (1) all biological pathways starting at the considered drug and ending at the disease of interest and (2) all biological pathways starting at drugs currently prescribed against that disease and ending at the disease of interest.

Pruning the Way to Reliable Policies: A Multi-Objective Deep Q-Learning Approach to Critical Care

no code implementations13 Jun 2023 Ali Shirali, Alexander Schubert, Ahmed Alaa

By disentangling accurate and approximated rewards through action pruning, potential distortions of the main objective are minimized, all while enabling the extraction of valuable information from intermediate signals that can guide the learning process.

AutoPrognosis: Automated Clinical Prognostic Modeling via Bayesian Optimization with Structured Kernel Learning

1 code implementation ICML 2018 Ahmed Alaa, Mihaela Schaar

AUTOPROGNOSIS optimizes ensembles of pipeline configurations efficiently using a novel batched Bayesian optimization (BO) algorithm that learns a low-dimensional decomposition of the pipelines’ high-dimensional hyperparameter space in concurrence with the BO procedure.
