Tracking fast changing non-stationary distributions with a
Neural document clustering techniques, e.g., self-organising map (SOM) or growing neural gas (GNG), usually assume that textual information is stationary on the quantity. However, the quantity of text is ever-increasing. We propose a novel dynamic... Self-Organizing Maps & DSOM – Neuro-Science project May 23, 2016 But as always in machine learning and inference, the target distribution is unknown. We assume that only unbiased observations x are available ( = 1 ), and so we de?ne the

observed stationary scale-free distributions, indicating that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems. [O2] The separations of the 108 shrines of the Panchakroshi encircling Varanasi appear to have a power law distribution with of ?= 1.5. Alternately stated, pilgrims create a fractal time series... ronments push the need for algorithms that can extract knowledge in a readily manner. Within this increasingly important field of research the application of artificial neu- ral networks to such task remains a fairly unexplored path. The self-organizing map (SOM) [1] is an unsupervised neural-network algorithm with topology preservation. The SOM has been applied extensively within fields

A Self-organizing Network for Computing A Posteriori Conditional Class Probability George W. Rogers, Jeffrey Solka, D. Stephen Malyevac, and Carey E. Priebe Abstract-This paper describes a neural network architecture whose goal is the computation of a posteriori conditional class probabilities for input vectors that belong to one of two input classes. The network architecture has been …

A Self-organizing Network That Can Follow Non-stationary Distributions Pdf

What is Comarch Self-organizing Network Solution? Mobile data traffic has grown 18-fold over the past five years, while mobile services are becoming more diverse, ranging from mobile broadband, through massive IoT, to mission-critical IoT.

• A self-organizing network that can follow non-stationary distributions, " (2000). Neural Networks for Modelling and Control of Dynamic Systems,
• A novel on-line criterion for identifying “useless” neurons of a self-organizing network is proposed and analyzed. The criterion is based on a utility measure. When it is used in the context of the growing neural gas model to guide deletions of units, the resulting method is able to closely track non-stationary distributions. Slow changes of the distribution are handled by adaptation of
