Data Mining via Support Vector Machines: Scalability, Applicability, and Interpretability
… and (3) discovering discriminant feature combinations---and presents solutions that are based on a principled methodology, i.e., Support Vector Machines (SVMs), to produce higher quality results with less human intervention. We first address several challenges in adopting SVM …

Automated classification of malignant melanoma based on detection of atypical pigment network in dermoscopy images of skin lesions
… multiple steps, involving lesion segmentation, feature extraction, feature combination and classification. In this research, a classifier-based approach for automatically selecting a lesion border mask for segmentation of dermoscopic skin lesion images is presented. A logistic regression based …

Use of linear predictive features and pattern recognition techniques to develop a vector quantization based blind SNR estimation system
… applied to estimate the SNR of speech signals. Features for the VQ system are derived from the speech signals through linear predictive analysis. The system is trained and tested on a range of 0 to 30 dB SNR in which codebook size, codebook spacing, training sets, and decision methods are …

A computational visual saliency model for images.
… Transform (DWT) to extract the local contrast features at multiple scales. The extracted local contrast features are integrated at multiple levels using a two-dimensional entropy-based feature combination scheme to derive a combined map. The combined map is normalized and enhanced using natural …

Hybrid models for combination of visual and textual features in context-based image retrieval.
… the visual words. Even the improved visual features will find it hard to capture an abstract semantic meaning of some queries, e.g. straight road in the USA. Textual features, on the other hand, would struggle with such queries as church with more than two towers as in many cases the …

Increasing information transfer rates for brain-computer interfacing
… knowledge that several independent EEG features can be observed for some mental states, I have developed a method for combining different and maybe independent features which improved performance. In some cases the performance of the combination algorithm outperforms the best single …
