Contextualized Machine Learning

no code implementations17 Oct 2023 Benjamin Lengerich, Caleb N. Ellington, Andrea Rubbi, Manolis Kellis, Eric P. Xing

Contextualized ML estimates heterogeneous functions by applying deep learning to the meta-relationship between contextual information and context-specific parametric models.

LLMs Understand Glass-Box Models, Discover Surprises, and Suggest Repairs

1 code implementation2 Aug 2023 Benjamin J. Lengerich, Sebastian Bordt, Harsha Nori, Mark E. Nunnally, Yin Aphinyanaphongs, Manolis Kellis, Rich Caruana

We show that large language models (LLMs) are remarkably good at working with interpretable models that decompose complex outcomes into univariate graph-represented components.

NOTMAD: Estimating Bayesian Networks with Sample-Specific Structures and Parameters

1 code implementation1 Nov 2021 Ben Lengerich, Caleb Ellington, Bryon Aragam, Eric P. Xing, Manolis Kellis

We encode the acyclicity constraint as a smooth regularization loss which is back-propagated to the mixing function; in this way, NOTMAD shares information between context-specific acyclic graphs, enabling the estimation of Bayesian network structures and parameters at even single-sample resolution.

Causal Mediation Analysis Leveraging Multiple Types of Summary Statistics Data

no code implementations24 Jan 2019 Yongjin Park, Abhishek Sarkar, Khoi Nguyen, Manolis Kellis

We can achieve necessary interpretation of GWAS in a causal mediation framework, looking to establish a sparse set of mediators between genetic and downstream variables, but there are several challenges.

Causal Inference

A latent topic model for mining heterogenous non-randomly missing electronic health records data

no code implementations1 Nov 2018 Yue Li, Manolis Kellis

Electronic health records (EHR) are rich heterogeneous collection of patient health information, whose broad adoption provides great opportunities for systematic health data mining.

Network Maximal Correlation

no code implementations15 Jun 2016 Soheil Feizi, Ali Makhdoumi, Ken Duffy, Muriel Medard, Manolis Kellis

For jointly Gaussian variables, we show that under some conditions the NMC optimization is an instance of the Max-Cut problem.
