threshold logic unit

A threshold logic unit (TLU) is a simple computational model used in digital circuits and neural networks. It takes several input signals, each representing a value, and combines them using weighted importance. If this combined value exceeds a specific threshold, the unit "fires" and produces an active output; otherwise, it remains inactive. Essentially, it acts like a decision-maker that determines whether the combined inputs are significant enough to trigger a response, allowing it to perform logical operations or mimic basic neuron functions in artificial intelligence systems.
