SOM tutorial part 1 Kohonen's Self Organizing Feature Maps Introductory Note This tutorial is the first of two related to self organising feature maps. Initially, this was just going to be one big comprehensive tutorial, but work demands and other time constraints have forced me to divide it into two. Nevertheless, part one should provide you with a pretty good introduction. SOM tutorial part 1

In natural language processing, latent Dirichlet allocation (LDA) is a generative model that allows sets of observations to be explained by unobserved groups that explain why some parts of the data are similar. For example, if observations are words collected into documents, it posits that each document is a mixture of a small number of topics and that each word's creation is attributable to one of the document's topics. LDA is an example of a topic model and was first presented as a graphical model for topic discovery by David Blei, Andrew Ng, and Michael Jordan in 2003.[1] Topics in LDA[edit] In LDA, each document may be viewed as a mixture of various topics. This is similar to probabilistic latent semantic analysis (pLSA), except that in LDA the topic distribution is assumed to have a Dirichlet prior.

Welcome to The Machine Learning Forum ロゴというのは企業の顔となる、文字やイラストを使った社名の表象のことで、有名なものは全世界的に通用するといった大きな影響力を持つものです。 特にインターネットなどで個性を出そうとすればそうした社名などを表したデザインに注目が集まるのでその効果は大きいと言えるでしょう。 ただそうした視覚的な訴求力に関してはある種の特殊技能であって、誰でも簡単に作れる、効果を挙げられるというわけでもないようです。 Welcome to The Machine Learning Forum
CRF Project Page The CRF package is a java implementation of Conditional Random Fields for sequential labeling developed by Sunita Sarawagi of IIT Bombay. The package is distributed with the hope that it will be useful for researchers working in information extraction or related areas. We have attempted to keep the core CRF package compact and barebones for ease of deployment. However, we have packaged additional supporting classes for generating features, managing model structure and dictionary of words in the training data. CRF Project Page

My research is in machine learning and statistics, with basic research on theory, methods, and algorithms. Areas of focus include nonparametric methods, sparsity, the analysis of high-dimensional data, graphical models, information theory, and applications in language processing, computer vision, and information retrieval. Perspectives on several research topics in statistical machine learning appeared in this Statistica Sinica commentary. This work has received support from NSF, ARDA, DARPA, AFOSR, and Google.

Amos Storkey - Research - Belief Networks Belief Networks and Probabilistic Graphical Models Belief networks (Bayes Nets, Bayesian Networks) are a vital tool in probabilistic modelling and Bayesian methods. They are one class of probabilistic graphical model. In other words they are a marriage between two important fields: probability theory and graph theory.

The Non-linearity and Complexity Research Group has high international visibility in the areas of pattern analysis, probabilistic methods, non-linear dynamics and the application of methods from statistical physics to the analysis of complex systems. The underpinning methodology used includes principled approaches from probabilistic modelling, Bayesian statistics, statistical mechanics and non-linear stochastic and deterministic differential equations. Particularly significant application domains include Biomedical Information Engineering and Signal Processing, Health Informatics, Environmental Modelling and Weather Forecasting, Error-correcting Codes and Multi-user Communication, Complex Systems and Networks, Solitons and Optical Fibers, and Chaos and turbulence.

The term "Pareto principle" can also refer to Pareto efficiency. The Pareto principle (also known as the 80–20 rule, the law of the vital few, and the principle of factor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.[1][2] Business-management consultant Joseph M. Juran suggested the principle and named it after Italian economist Vilfredo Pareto, who observed in 1906 that 80% of the land in Italy was owned by 20% of the population; Pareto developed the principle by observing that 20% of the pea pods in his garden contained 80% of the peas.[2] It is a common rule of thumb in business; e.g., "80% of your sales come from 20% of your clients". Mathematically, the 80-20 rule is roughly followed by a power law distribution (also known as a Pareto distribution) for a particular set of parameters, and many natural phenomena have been shown empirically to exhibit such a distribution.[3]
