چکیده

Support Vector Machines (SVMs) is basically a discriminative classifiers, while it is hopefully that incorporating probability into SVMs will achieve better performance. This paper briefly reviews some of the methods that can be used to carry out the combination. By following one of them, we make it suitable for the task of speaker recognition, and Gaussian Mixture Models (GMM) is used as the generative model to derive Fisher kernel. Preliminary experiments are performed on a speaker identification task. The results are compared with GMM and standard SVMs baseline systems, and some suggestions have been made for future direction.

Speaker Recognition System for Limited Speech Data Using High-Level Speaker Specific Features and Support Vector Machines

High-level speaker-specific features (HLSSFs), such as the style of pronunciation of words, their use, phonotactics and prosody, form the main subjects of state-of-the-art research on automatic speaker recognition (ASR). In this paper, we experimentally verify HLSSF extraction and support vector machine (SVM)-based modelling techniques. The HLSSF extraction produces patterns of symbols for each...

Dynamic Time-Alignment Kernel in Support Vector Machine

A new class of Support Vector Machine (SVM) that is applicable to sequential-pattern recognition such as speech recognition is developed by incorporating an idea of non-linear time alignment into the kernel function. Since the time-alignment operation of sequential pattern is embedded in the new kernel function, standard SVM training and classification algorithms can be employed without further...

A hybrid EEG-based emotion recognition approach using Wavelet Convolutional Neural Networks (WCNN) and support vector machine

Nowadays, deep learning and convolutional neural networks (CNNs) have become widespread tools in many biomedical engineering studies. CNN is an end-to-end tool which makes processing procedure integrated, but in some situations, this processing tool requires to be fused with machine learning methods to be more accurate. In this paper, a hybrid approach based on deep features extracted from Wave...

Automatic Language Identification with Discriminative Language Characterization Based on SVM

Robust automatic language identification (LID) is the task of identifying the language from a short utterance spoken by an unknown speaker. The mainstream approaches include parallel phone recognition language modeling (PPRLM), support vector machine (SVM) and the general Gaussian mixture models (GMMs). These systems map the cepstral features of spoken utterances into high level scores by class...
