Description:

AMiDST is a Java Toolbox for Scalable Probabilistic Machine Learning.

In AMiDST, you can model your problem using a flexible probabilistic language based on graphical models. Then, fit it with data using a Bayesian approach to handle modelling uncertainty.

AMIDST provides tailored parallel and distributed implementations of Bayesian parameter learning for batch and streaming data (multi-core and distributed processing). This processing is based on flexible and scalable message passing algorithms.

MAIN FEATURES

• Probabilistic Graphical Models: You can specify your model using probabilistic graphical models with latent variables and temporal dependencies.

• Scalable inference: Perform inference on your probabilistic models with powerful approximate and scalable algorithms based on novel variational message passing schemes.

• Data Streams: Update your models when new data is available. This makes our toolbox appropriate for learning from (massive) data streams.

• Large-scale Data: Use your defined models to process massive data sets in a distributed computer cluster using Flink or Spark.

• Extensible: Code your models or algorithms within AMiDST and expand the toolbox functionalities. Flexible toolbox for researchers performing their experimentation in machine learning.

• Interoperability: Leverage existing functionalities and algorithms by interfacing to other software tools such as Hugin, MOA, Weka, R, etc.
