Infima - LAN

Infima

Infima is a family of software utilities for archiving and compressing files on the Microsoft Windows and Linux platforms. The proprietary compression format used by the Infima utilities is also termed LAN.

Infima was originally developed in beginning 2006 by Nir Halowani and Lilia Demidov, PhD students at Applied Mathematics. It combined the fork-combining utilities such as Zip with newer compression algorithms.

The Infima LAN formats remain, unlike some other file compression, proprietary, and Infima Technologies charge license fees for its use in other programs.

LAN format

The general concept of the system consists of a neural network data compression comprised of N levels of neural network using a weighted average of N pattern-level predictors. The LAN format use of N levels neural network to combine models. Using a bit level predictions which specializes in different types of data integrated using a weighted combination of predictions. The algorithm used by Infima is considered a descendant of the PAQ algorithms using LAN proprietary context modeling.
