A view of Estimation of Distribution Algorithms through the lens of Expectation-Maximization

no code implementations24 May 2019 David H. Brookes, Akosua Busia, Clara Fannjiang, Kevin Murphy, Jennifer Listgarten

We show that a large class of Estimation of Distribution Algorithms, including, but not limited to, Covariance Matrix Adaption, can be written as a Monte Carlo Expectation-Maximization algorithm, and as exact EM in the limit of infinite samples.

Next-Step Conditioned Deep Convolutional Neural Networks Improve Protein Secondary Structure Prediction

no code implementations13 Feb 2017 Akosua Busia, Navdeep Jaitly

This sequential model achieves 70. 3% Q8 accuracy on CB513 with a single model; an ensemble of these models produces 71. 4% Q8 accuracy on the same test set, improving upon the previous overall state of the art for the eight-class secondary structure problem.

Protein Secondary Structure Prediction Using Deep Multi-scale Convolutional Neural Networks and Next-Step Conditioning

no code implementations4 Nov 2016 Akosua Busia, Jasmine Collins, Navdeep Jaitly

We first train a series of deep neural networks to predict eight-class secondary structure labels given a protein's amino acid sequence information and find that using recent methods for regularization, such as dropout and weight-norm constraining, leads to measurable gains in accuracy.
