 coals_vectors(+WindowType, +WindowSize, -CoalsVectors) is det

CoalsVectors is a list of (Word,Vector) tuples, where Vector is a real-valued COALS vector, derived from a DCG using a WindowType of WindowSize.

 coals_write_vectors(+Tuples, +File) is det

Writes a list of (Word,Vector) Tuples to File in CSV format.

 coals_binary_vectors(+WindowType, +WindowSize, -CoalsVectors) is det

CoalsVectors is a list of (Word,Vector) tuples, where Vector is a binary COALS vector, derived from a DCG using a WindowType of WindowSize. Binary COALS vectors are derived from real-valued COALS vectors, by setting positive correlations to hot bits (i.e., 1s).

 coals_padded_binary_vectors(+WindowType, +WindowSize, +NHotPaddingBits, -CoalsVectors) is det

CoalsVectors is a list of (Word,Vector) tuples, where Vector is a binary COALS vector, derived from a DCG using a WindowType of WindowSize. Binary vectors are padded with a a minimal binary identifier containing NHotPaddingBits, in such a way that the identifiers for similar binary vectors do not share any features.
