This paper describes an optimal approach for feature extraction and selection for classification of leaves based on Genetic Algorithm (GA). The selection of the optimal features subset and the classification has become an important methodology in the field of Leaf classification. The deterministic feature sequence is extracted from the leaf images using GA technique, and these extracted feature...

The problem of context recognition from mobile audio data is considered. We consider ten different audio contexts (such as car, bus, office and outdoors) prevalent in daily life situations. We choose mel-frequency cepstral coefficient (MFCC) parametrization and present an extensive comparison of six different classifiers: knearest neighbor (kNN), vector quantization (VQ), Gaussian mixture model...

This paper explores the potential of machine learning algorithms for weed and crop classification from UAV images. The identification weeds in crops is a challenging task that has been addressed through orthomosaicing images, feature extraction labelling images to train algorithms. In this paper, performances several algorithms, random forest (RF), support vector (SVM) k-nearest neighbours (KNN...

Data Mining was a basic technique for examine the data in a choice of perception and categorizes it and finally to compress it. Classification was used to expect cluster relationship for data instances in data mining. Many key types of classification techniques including KNN, Bayesian classification, and Decision tree (DT) induction, C4.5, ID3, SVM, and ANN are used for classification. The majo...

Recognition of Devanagari scripts is challenging problems. In Optical Character Recognition [OCR], a character or symbol to be recognized can be machine printed or handwritten characters/numerals. There are several approaches that deal with problem of recognition of numerals/character. In this paper we have compared SVM and KNN on handwritten as well as on printed character and numerical databa...
