PySL is a package that makes S-Lang functions and variables accessible via Python. It allows any S-Lang data type to move from S-Lang to Python scope and back. It also lets the user call any intrinsic or user-defined S-Lang function (including those defined by imported modules) from Python. All of this can be accomplished using a simple, module-like interface.
PyMML is a Python package for the statistical analysis and automatic classification of data. It implements a selection of the MML estimators described by Professor Chris Wallace in "Statistical and Inductive Inference by Minimum Message Length". MML is a form of robust statistical analysis based on information theory. The package includes estimators for hidden factor analysis and mixture modelling.
Tripoli is a Python implementation of a "triple space": that is, a triple store with tuple space semantics. It supports the synchronization of concurrent processes via a shared data structure. Processes can add triples to the store, and read or take triples from the store using pattern matching. If a triple matching a pattern is not yet in the store, a query will block until a suitable triple is added by some other process. Many synchronization patterns can be expressed using these primitives. Tripoli extends the semantics of tuple spaces with two additional operations, copy_graph and copy_collect_graph. These copy or move the graph of all triples that are connected to a given subject to a new triple space, and can be used together with the other pattern matching operations to express procedural queries over triple data.
