Item Case-based reasoning control of biological wastewater treatment(2014-01-01) Atanassov A.; Boshnakov K.The paper presents the usage of Case-Based Reasoning (CBR) approach for supervisory control of Wastewater Treatment Plants (WWTP) intended to better water purification. Proposed CBR supervisory control of WWTP is based on the cases. Each case contains specific regulators setpoints, corresponding to different situation in the plant, caused by different internal or external factors. Instead of solving on-line optimal control tasks CBR approach was applied. So, the regulators set-points are selected on the base of similarity between current situation (case) and already available solutions in the case-base database.Item MULTIMODAL SYSTEM FOR FACIAL EMOTION RECOGNITION BASED ON DEEP LEARNING(2024-01-01) Atanassov A.; Pilev D.; Tomova F.Emotions are one of the main ways of communication between people and of expressing attitudes towards objects, products, services, etc. They are divided to verbal and non-verbal classes. Human speech and intonation belong to the first class, and to the second (non-verbal) facial and body emotions, known as body language. The subject of this report is the development of multimodal deep learning system intended to recognize facial and body emotions and their relationship with the scene (weather) in which they occur. It is based on three deep learning neural networks (DNN) each one for recognition of facial emotion, body emotion and weather. Combining their results, we improve significantly the final facial emotion recognition (FER) results.
