DynaML

Aim

DynaML is a scala library/repl for implementing and working with general Machine Learning models. Machine Learning/AI applications make heavy use of various entities such as graphs, vectors, matrices etc as well as classes of mathematical models which deal with broadly three kinds of tasks, prediction, classification and clustering.

The aim is to build a robust set of abstract classes and interfaces, which can be extended easily to implement advanced models for small and large scale applications.

But the library can also be used as an educational/research tool for data analysis.

Currently DynaML supports.

Regularized Ordinary Least Squares
Logistic and Probit Models for binary classification
Regression and Classification with kernel based Dual LS-SVM
Regression and Classification with Gaussian Processes
Feed forward Neural Networks
Committee Models
- Neural Committee Models
- Gaussian Process Committee Models
Model Learning and Optimization
- Gradient Descent
- Conjugate Gradient
- Committee Model Solver
- Back propogation with momentum
- LSSVM linear solver
Model tuning
- Grid Search
- Maximum Likelihood (ML-II)
- Coupled Simulated Annealing
Model validation metrics (RMSE, Area under ROC)
Entropy based data subset selection
Data Pipes for configurable workflows

Include

To include DynaML in your maven JVM project edit your pom.xml file as follows

<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
</repositories>

<dependency>
    <groupId>com.github.mandar2812</groupId>
    <artifactId>DynaML</artifactId>
    <version>v1.4</version>
</dependency>

for sbt projects edit your build.sbt (see JitPack for more details)

    resolvers += "jitpack" at "https://jitpack.io"
    libraryDependencies += "com.github.User" % "Repo" % "Tag"

Installation

Platform Compatibility

Currently DynaML installs and runs on *nix platforms, though it is possible to build the project on windows, running the generated .bat file might not work and one would need to resort to using the java -jar command.

Pre-requisites

sbt
A modern HTML5 enabled browser (to view plots generated by Wisp)
BLAS, LAPACK and ARPACK binaries for your platform. In case they are not installed, it is possible to disable this feature by commenting out (//) the section of the build.sbt file given below.
```
  "org.scalanlp" % "breeze-natives_2.11" % "0.11.2" % "compile",
```

Steps

Clone this repository
Run the following.

sbt

The sbt shell will open

 [info] Loading project definition from ~/DynaML/project
 [info] Set current project to DynaML (in build file:~/Development/DynaML/)
 >

Now enter the following commands

>stage
>console

After the project builds, you should get the following prompt.
