Title: Bio-Inspired Optimization of Type-2 Fuzzy Logic Systems

Oscar Castillo Spearker: Oscar Castillo, Tijuana Institute of Technology, Tijuana, Mexico

Abstract: The design of Type-2 fuzzy logic systems is a complex task and in general achieving an optimal configuration of structure and parameters is time consuming and can rarely be found. For this reason the use of bio-inspired optimization algorithms offer a good hybrid solution to find near optimal design of type-2 fuzzy logic systems in real world applications. In particular, type-2 fuzzy control offers a real challenge because the problems in this area require very efficient and accurate solutions, as is the case for robotic applications. Another, area of application is type-2 fuzzy image processing. In this talk we present a general scheme for optimizing type-2 fuzzy systems with bio-inspired optimization techniques, like ant colony optimization, the chemical reaction algorithm, bee colony optimization and others.

Title: Deep Learning Architectures for Sentiment Analysis in Textual and Video Data

Alexander Gelbukh Spearker: Alexander Gelbukh, Instituto Politécnico Nacional, Mexico City, Mexico

Abstract: Sentiment analysis is a very active area of research that aims at identification of sentiment (positive or negative) or emotions expressed by humans, for example, in text or speech. Among its numerous practical applications, one can mention opinion mining in Internet and social networks, educational and healthcare applications, bullying and suicide prevention, and crime prevention. While the task of sentiment detection and classification seems easy, it meets various tough problems such as treatment of multiword expressions, identification of desirable facts, or sarcasm detection. Recently, deep-learning techniques have been shown to be especially effective on sentiment analysis tasks. In our research group, we experiment with deep-learning architectures for sentiment analysis and related tasks, in particular, sentiment analysis in video data, where the sentiment can be inferred from facial expressions, voice, and meaning of the speech. After an introduction in the area of sentiment analysis, I will present some of our recent results in this task.
