Som algorithm and its variant
WebAug 7, 2024 · SOM’s architecture : Self organizing maps have two layers, the first one is the input layer and the second one is the output layer or the feature map. Unlike other ANN types, SOM doesn’t have activation function in neurons, we directly pass weights to output layer without doing anything. Each neuron in a SOM is assigned a weight vector with ... WebOct 9, 2009 · In this paper, a variant of the SOM algorithm is presented called the SOM-based optimization (SOMO) algorithm, which may be regarded as a new approach to a model of social influence and social learning. The conventional self-organizing feature map (SOM) algorithm is usually interpreted as a computational model, which can capture main …

WebConstrained optimization problems (COPs) are widely encountered in chemical engineering processes, and are normally defined by complex objective functions with a large number of constraints. Classical optimization methods often fail to solve such problems. In this paper, to solve COPs efficiently, a two-phase search method based on a heat transfer search … WebAn important variant of the basic SOM is the batch algorithm. In it, the whole training set is gone through at once and only after this the map is updated with the net effect of all the samples. Actually, the updating is done by simply replacing the prototype vector with a weighted average over the samples, where the weighting factors are the neighborhood …
