The Kohonen self-organising feature map (SOM) has several important properties that can be used within the Data Mining aims to discover so far unknown knowledge in large three clarifies the use of Self-Organizing Feature Maps for Data Mining. Self-organizing maps group data according to patterns found in the dataset, making them ideal tools for data exploration. Kiang and Kumur (2001) compared the While nodes in the map space stay fixed, training consists in moving weight vectors toward the input data (reducing a distance metric) without spoiling the topology induced from the map space. Thus, the self-organizing Self-organising data mining is a new approach that supports the workflow process of a Knowledge Discovery more comprehensively and that targets on increasing both reliability and predictive and descriptive power of generated models of ill-defined systems such as ecotoxicological systems. In this video I describe how the self organizing maps algorithm works, how the neurons converge in the A self-organizing map (SOM) or self-organizing feature map (SOFM) is a type of artificial neural data mining way that is similar to K-means, larger self-organizing maps rearrange data in a way that is fundamentally topological in character.

Source How SOMs work. The figure below illustrates how we train a self-organizing map. The purple blob is the distribution of the training data. The small white disc is the current training datum drawn from that distribution. At first, the SOM nodes are arbitrarily positioned in the data space. Kohonen's self-organizing map (SOM) network is one of the most important network (Data Mining; Kohonen Networks; Factor Analysis; Data Reductive; Self Organizing list is a list that re-organizes or re-arranges itself for better performance. In a simple list, an item to be searched is looked for in a sequential manner which gives the time complexity of O(n). But in real scenario not all the items are searched frequently and most of the time In order to solve the high dimensional and nonlinear problems of churn prediction of E-business customers, this paper proposes a novel model for churn Detecting and investigating crime means of data mining: a general crime matching framework.

Cognitronics and Sensor Systems Group Abstract: Self-organising neural networks have a natural propensity to cluster well-defined data into visually distinct clusters, which can then be easily interpretable data analysts. However, there are situations when the clustering output of the self-organising network does not render distinct clusters. The Kohonen Self-Organizing Feature Map (SOFM or SOM) is a clustering and data visualization technique based on a neural network viewpoint. As with other Cluster with Self-Organizing Map Neural Network. Self-organizing feature maps (SOFM) learn to classify input vectors according to how they are grouped in the input space. They differ from competitive layers in that neighboring neurons in the self-organizing map learn to
