I look forward to learning NLP and deep learning. Based on my knowledge of machine learning and deep learning, I started to come up with an existing idea. I have developed an emotion detection project using commonsense knowledge on popular datasets such as EmoryNLP, Iemocap, Meld, DailyDialog. There are some challenges such as imbalanced dataset, overfitting and so on. My achievement through this project is adding an attention layer to the model to gain more accurate results.
