Som algorithm and its variant
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 … WebAbstract. In order to create spatially ordered and organized representations of input occurrences in a neural network, the most essential principle seems to be to confine the learning corrections to subsets of network units that lie in the topological neighborhood of the best-matching unit. There seems to exist an indefinite number of ways to ...

We recapture some of the arguments for trust-based technologies in ubiquitous computing, followed by a brief survey of some of the models of trust that have been introduced in this respect. Based on this, we argue for the need of more formal and foundational trust models. Andre forfattere.

WebDec 1, 2014 · The Self-Organizing Map (SOM) is an unsupervised learning algorithm introduced by Kohonen [1]. In the area of artificial neural networks, the SOM is an excellent data-exploring tool as well [2]. It can project high-dimensional patterns onto a low-dimensional topology map. The SOM map consists of a one or two dimensional (2-D) grid … • The generative topographic map (GTM) is a potential alternative to SOMs. In the sense that a GTM explicitly requires a smooth and continuous mapping from the input space to the map space, it is topology preserving. However, in a practical sense, this measure of topological preservation is lacking. • The time adaptive self-organizing map (TASOM) network is an extension of the basic SOM. The TASOM employs adaptive learning rates and neighborhood functions. It also includes …

WebThe most common algorithm uses an iterative refinement technique. Due to its ubiquity it is often called the k-means algorithm; it is also referred to as Lloyd's algorithm, particularly in the computer science community.
