TLDR
A new class of support vector algorithms for regression and classification that eliminates one of the other free parameters of the algorithm: the accuracy parameter in the regression case, and the regularization constant C in the classification case.
Abstract
We propose a new class of support vector algorithms for regression and classification. In these algorithms, a parameter ν lets one effectively control the number of support vectors. While this can be useful in its own right, the parameterization has the additional benefit of enabling us to eliminate one of the other free parameters of the algorithm: the accuracy parameter epsilon in the regression case, and the regularization constant C in the classification case. We describe the algorithms, give some theoretical results concerning the meaning and the choice of ν, and report experimental results.

Optimal Arousal Identification and Classification for Affective Computing Using Physiological Signals: Virtual Reality Stroop Task

TL;DR: A Virtual Reality Stroop Task from the Virtual Reality Cognitive Performance Assessment Test is made use to identify the optimal arousal level that can serve as the affective/cognitive state goal and results suggest that high classification rates can be achieved when a support vector machine is used to classify the psychophysiological responses.

Predicting Visual Exemplars of Unseen Classes for Zero-Shot Learning

TL;DR: Zhang et al. as mentioned in this paper proposed a novel zero-shot learning model that takes advantage of clustering structures in the semantic embedding space, which reduces to training multiple kernel-based regressors from semantic representation-exemplar pairs from labeled data of the seen object categories.

Multi-facet Rating of Product Reviews

TL;DR: In this paper, the authors focus on multi-facetive review rating, i.e., on the case in which the review of a product (eg, a hotel) must be rated several times, according to several aspects of the product (for a hotel: cleanliness, centrality of location, etc) and explore the vectorial representations of the text by means of POS tagging, sentiment analysis, and feature selection for ordinal regression learning.

Modeling of the Thermal State Change of Blast Furnace Hearth With Support Vector Machines

TL;DR: A highly efficient ordinal-validation algorithm is proposed to combine with the F-score method to single out inputs from all collected blast furnace variables, which are then fed into the constructed models and indicate that these two models both can serve as competitive tools for the current predictive task.
