What Does Liquid State Machine (LSM) Mean?

A liquid state machine (LSM) is a machine learning model or system that is part of a series of particular neural network models. These models build on traditional designs to introduce new and innovative ways of processing information. Like other kinds of neural networks, liquid state machines and similar builds are based around the neurobiology of the human brain.

Techopedia Explains Liquid State Machine (LSM)

To really understand what a liquid state machine is, it is important to understand the type of machine learning program into which it falls. These types of machine learning are sometimes called “third-generation” neural networks, and many experts refer to “spiking” neural networks to illustrate how they work. The spiking neural network, which utilizes many of the same models as a liquid state machine, adds a property of time to synaptic and neural elements.
