To address this deficiency, we have developed a supervised learning algorithm for the detection of subtypes of chirps-frequency/amplitude modulations of the electric organ discharge that are generated predominantly during electric interactions of individuals of the weakly electric fish Apteronotus lepto...
The term “Gradient” in Gradient Boosting refers to the fact that you have two or more derivatives of the same function (we’ll cover this in more detail later on). Gradient Boosting is aniterative functional gradient algorithm, i.e an algorithm which minimizes a loss function by iteratively...
Supervised analyses Supervised structure detection assumed that if a computational algorithm can be trained with pain threshold data to assign a subject to the correct class, i.e., sex, so that it can infer the sex of new subjects from their pain threshold pattern, then the pain thresholds con...
2021). Furthermore, the number of clusters in a mode serves as the distinctive identifier for that mode. Hence different modes are discovered by varying the free parameter “σ” which embodies the zooming effect in the Standard Spectral Clustering algorithm, this process is known as “Sigma ...

We show that this can drastically improve the precision of answered questions while only not answering a limited number of previously correctly answered questions. Employing a supervised learning strategy using depth-first-search paths to bootstrap the reinforcement learning algorithm further improves ...
We selected the top principal components (PCs) which cumulatively account for at least 80% of total variation as input into the Uniform Manifold Approximation and Projection (UMAP) algorithm50. Selecting only the top PCs accounting for majority of variation helps suppress noise51, allowing better ...

The aim of this chapter is still to provide readers with the essentials of computational molecular evolution, offering a brief overview of recent progress, both in terms of modeling and algorithm development. Some of the details will be left out as they are dealt with by others in this volume...
