I have only heard about Keras, a language widely used in artificial intelligence and machine learning, but I have not had many opportunities to learn or experience it directly. This course has given me the opportunity to study programming in more specialized and special cases, having only studied general-purpose languages such as Python and C. I highly recommend this course to those who are interested in artificial intelligence and machine learning, but I would also like to recommend it to those who want to continue the challenge of acquiring professional programming knowledge and skills. I will diligently take the remaining courses. Thank you^^
