As part of the Ideal R&D Seminar, we were together with Dr Onur Güngör, Computer Engineering Faculty Member at Boğaziçi University and Udemy Data Science Team Leader. In our seminar titled "ChatGPT: The Incredible Results of Predicting the Next Word", we followed the evolution of word representations, which are the basis of natural language processing, and examined big language models and #ChatGPT practices.
