Deep Emotion Recognition using Wearable Sensors

Emotion recognition is an emerging interdisciplinary field that integrates methodologies from affective computing, sentiment analysis, signal processing, and machine learning. This project focuses on classifying emotions such as amusement and stress using physiological signals like heart rate and skin conductivity, collected via wearables. To build the model, a hybrid approach was employed that combines various deep learning architectures, including Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) networks. This approach is capable of accurately capturing changes in physiological signals to identify specific emotional states.

The performance of the model has been rigorously evaluated using a variety of metrics, including accuracy, precision, recall, and F1-score. To fine-tune the model's performance, hyperparameter tuning was conducted using grid search and Bayesian optimization techniques. The model achieved an accuracy rate of 92% under a 5-fold cross-validation setting. As wearable technology continues to evolve, this project serves as a significant contribution to the development of real-time affective computing systems that could be integrated into future generations of a wide range of wearable products, from smartwatches to health monitors.

Advancing Water Safety : An Early Warning System to Monitor and Evaluate Drinking Water Quality

An early warning system was developed that can enhance the safety and quality of drinking water in Turkiye by identifying hazardous contaminants such as E. coli O157:H7, anthrax, and ricin. Utilizing a hybrid approach that integrates various statistical methods like Z-score analysis, moving averages, control charts, and weighted voting, the system was designed to provide real-time monitoring and detect unexpected levels of multiple parameters, including temperature, pH, total organic carbon, conductivity, oxidation-reduction potential, free chlorine, and dissolved oxygen.

Plots for Early Warning System

The idea with employing a multi-tiered approach is to facilitate early intervention for minor deviations while enabling immediate action for more severe anomalies. It has the potential for wide-ranging applications, not just limited to municipal water treatment plants but also extending to main storage and distribution lines, thereby serving as a critical tool with the capability to safeguard public health and environmental integrity.
