Hybridizing sparse component analysis with genetic algorithms for microarray analysis
Nonnegative matrix factorization (NMF) has proven to be a useful tool for the analysis of nonnegative multivariate data. However, it is known not to lead to unique results when applied to blind source separation (BSS) problems. In this paper we present an extension of NMF capable of solving the BSS problem when the underlying sources are sufficiently sparse. In contrast to most well-established...
متن کاملGenetic Algorithms for Component Analysis
Adapted waveform analysis is used extensively in audio, speech, and video coding. In this context, the basic problem is to nd out the best representation for a given signal. The strategy is to decompose the signal into time-frequency atoms. The main analysis tool is the expansion of the signal in orthonormal bases whose elements have good time-frequency localizations. We show that genetic algor...

متن کاملSparse Structured Principal Component Analysis and Model Learning for Classification and Quality Detection of Rice Grains
In scientific and commercial fields associated with modern agriculture, the categorization of different rice types and determination of its quality is very important. Various image processing algorithms are applied in recent years to detect different agricultural products. The problem of rice classification and quality detection in this paper is presented based on model learning concepts includ...
متن کاملSparse Principal Component Analysis
Principal component analysis (PCA) is widely used in data processing and dimensionality reduction. However, PCA suffers from the fact that each principal component is a linear combination of all the original variables, thus it is often difficult to interpret the results. We introduce a new method called sparse principal component analysis (SPCA) using the lasso (elastic net) to produce modified...
