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.

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.

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.
