Crate vikos

A machine learning library for supervised regression and classifaction

This library wants to enable its users to write models independently of the teacher used for training or the cost function that is meant to be minimized. To get started right away, you may want to have a look at the tutorial.

Modules

cost

crisp

Contains implementations for crisp trait

linear_algebra

Defines linear algebra traits used for some model parameters

model

Implementations of Model trait

teacher

Learning algorithms implementing Teacher trait

tutorial

A short tutorial on how to use vikos to solve the problem of supervised machine learning: We want to predict values for a quantity (the target), and we have some data that we can base our inference on (features). We have a data set (a history), that consists of features and corresponding, true target values, so that we have a base to learn about how the target relates to the feature data. To do this we choose a function which relates the features to the target (the model). This model depends on coefficients which are determined using a training algorithm and the history. (teacher).

Traits

Cost

Representing a cost function whose value is supposed be minimized by the training algorithm.

Crisp

Define this trait over the target type of a classifier, to convert it into its truth type

Model

A parameterized expert algorithm

Teacher

Algorithms used to adapt Model coefficients

Functions

learn_history

Teaches model all events in history
