Threshold logic

Nodes that employ a step activation function are sometimes known as threshold logic units (TLUs). 

Automated repetition of the sample injection after one fractionation cycle which is indicated by a signal decrease of a concentration detector to the baseline signal. If samples with multimodal distributions are to be fractionated, the threshold logic for sample reinjection needs to be modified accordingly.

The continuous discriminant s is usually compared with some constant value in a "threshold logical unit" (TLU). The output of the TLU is used... 

A "committee machine uses several different classifiers for the same classification problem in a parallel manner. The classifiers may stem e.g. from different training processes with the same training set. The results (scalar products) are summarized to give the final classification. Threshold logical units are usually applied and the majority of votes determines the class membership. Correct classification for all members of the training set may be obtained by a committee machine even if the data set is not Linearly separable. Unfortunately, no exhaustive theory about the training of several parallel classifiers exists. 

Some logic gates such as four-junction logic (4JL) (59,60) and modified variable threshold logic (MVTL) (73,75,76) have been fabricated using NbN junctions. The smallest logic delay... 

Unlike other authors, we choose from the beginning to characterize each element i of a system both by a logical variable ot, ( internal variable) associated with its concentration (or, more generally, its level) and by a logical function a, associated with its rate of production (or, more generally, its flux). Variable a = 1 if the concentration exceeds a functional threshold, a = 0 if not.t Function a = 1 if the rate of production...
