Beyond the training set: an intuitive method for detecting distribution shift in model-based optimization

no code implementations9 Nov 2023 Farhan Damani, David H Brookes, Theodore Sternlieb, Cameron Webster, Stephen Malina, Rishi Jajoo, Kathy Lin, Sam Sinai

A common scenario involves using a fixed training set to train models, with the goal of designing new samples that outperform those present in the training data.

Contrastive losses as generalized models of global epistasis

no code implementations4 May 2023 David H. Brookes, Jakub Otwinowski, Sam Sinai

Here we demonstrate that minimizing contrastive loss functions, such as the Bradley-Terry loss, is a simple and flexible technique for extracting the sparse latent function implied by global epistasis.

Forecasting labels under distribution-shift for machine-guided sequence design

no code implementations18 Nov 2022 Lauren Berk Wheelock, Stephen Malina, Jeffrey Gerold, Sam Sinai

The ability to design and optimize biological sequences with specific functionalities would unlock enormous value in technology and healthcare.

AdaLead: A simple and robust adaptive greedy search algorithm for sequence design

1 code implementation5 Oct 2020 Sam Sinai, Richard Wang, Alexander Whatley, Stewart Slocum, Elina Locane, Eric D. Kelsic

In this work, we implement an open-source Fitness Landscape EXploration Sandbox (FLEXS: github. com/samsinai/FLEXS) environment to test and evaluate these algorithms based on their optimality, consistency, and robustness.

Bayesian Optimization

A primer on model-guided exploration of fitness landscapes for biological sequence design

no code implementations4 Oct 2020 Sam Sinai, Eric D Kelsic

This primer can serve as a starting point for researchers from different domains that are interested in the problem of searching a sequence space with a model, but are perhaps unaware of approaches that originate outside their field.

BIG-bench Machine Learning Experimental Design

Variational auto-encoding of protein sequences

2 code implementations9 Dec 2017 Sam Sinai, Eric Kelsic, George M. Church, Martin A. Nowak

Here we present an embedding of natural protein sequences using a Variational Auto-Encoder and use it to predict how mutations affect protein function.

Protein Design

Primordial Sex Facilitates the Emergence of Evolution

no code implementations2 Dec 2016 Sam Sinai, Jason Olejarz, Iulia A. Neagu, Martin A. Nowak

Compartments are ubiquitous throughout biology, yet their importance stretches back to the origin of cells.
