PRISM: PRogramming In Statistical Modeling

PRISM is a general programming language intended for symbolic-statistical modeling. It is a new and unprecedented programming language with learning ability for statistical parameters embedded in programs. Its programming system is a powerful tool for building complex statistical models.

Installation

1. Download pre-build package from release page:

If you want to install the latest development version package pre-built with the latest version of ubuntu (the latest version from github is automatically built), you can install it with the following command.

wget "https://github.com/prismplp/prism/releases/download/v2.4.2a(T-PRISM)-prerelease/prism_linux_dev.auto.tar.gz"

2. Extract binaries and sample programs.

If you downloaded a different release version, please change the file name and unzip it in the same way.

tar xvf prism_linux_dev.auto.tar.gz

3. Setting the proper environmental variable:

export PATH=<current directory>/prism/bin:${PATH}

4. Try!

$ prism

Press Ctrl+D to quit the interactive mode.

T-PRISM: Tensorized-PRISM (Pre-release)

T-PRISM is a new logic programming language based on tensor embeddings. Our embedding scheme, named tensorized semantics, is a modification of the distribution semantics in PRISM, one of the state-of-the-art probabilistic logic programming languages, by replacing distribution functions with multidimensional arrays.
