This ground-breaking text/reference diverges from the traditional view that computer vision (for image analysis) and string processing (for text mining) are separate and unrelated fields of study, propounding that images and text can be treated in a similar manner for the purposes of information retrieval, extraction and classification. Highlighting the benefits of knowledge transfer between the two disciplines, the text presents a range of novel similarity-based learning techniques founded on this approach.

Topics and features:

• Describes a variety of similarity-based learning approaches, including nearest neighbor models, local learning, kernel methods, and clustering algorithms
• Presents a nearest neighbor model based on a novel dissimilarity for images, and applies this for handwritten digit recognition and texture analysis
• Discusses a novel kernel for (visual) word histograms, as well asseveral kernels based on pyramid representation, and uses these for facial expression recognition and text categorization by topic
• Introduces an approach based on string kernels for native language identification
• Contains links for downloading relevant open source code

• With a foreword by Prof. Florentina Hristea

  This unique work will be of great benefit to researchers, postgraduate and advanced undergraduate students involved in machine learning, data science, text mining and computer vision.
