Title: Optimization of modular granular neural networks using bio-inspired optimization algorithms with fuzzy parameter adaptation for human recognition

Melin, Patricia Spearker: Patricia Melin, Tijuana Institute of Technology, Tijuana, Mexico

Abstract: In this talk, new models of modular neural networks optimized with bio-inspired optimization algorithms using fuzzy parameter adaptation are proposed. The models use a granular approach based on analyzing database complexity. In this case the proposed method is tested with the problem of human recognition based on face information. The ORL and the ESSEX face databases are used to test the effectiveness of the proposed method. To compare with other related works using the same databases, four cases are established (3 for the ESSEX Database and 1 for the ORL Database). The results using the proposed method are better than the results achieved by other works, and this affirmation is based on a statistical comparison of results. The main idea is to design the architectures of modular neural networks using bio-inspired optimization methods, such as particle swarm optimization, grey wolf optimization and the firefly algorithm. The distribution of persons in each granule is determined by an initial analysis, resulting in a grouping of data with the same complexity. The proposed method allows the optimization of multiple modular neural networks that use different sizes of data sets for the training phase, which means that multiple results can be obtained.

Title: Opinion Mining and Sentiment Analysis with Deep Learning Techniques

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

Abstract:Opinion mining is an active area of research that has recently attracted much interest from research community, industry, government, and political circles. Opinion mining aims to process the huge body of user-contributed content in Internet and social networks to extract user’s opinions, suggestions, and feedback on a very wide range of products, services, issues, or political figures and use this information to help decision making in industry and politics, as well as to help consumers to make informed purchasing decisions. Sentiment analysis is the main subtask of opinion mining. It consists in determining whether a given opinion (such as review, tweet, or a video clip) is positive or negative or what emotion it expresses. Other subtasks of opinion mining include author profiling and deception detection. I will present some deep-learning architectures developed in our group for utterance-level sentiment analysis in texts and video clips, as well as for determining the psychological type of the author of a text.
