Firstly it is good to hear that you are looking to upskill yourself in Artificial Intelligence being from Banking sector. There are various websites available to learn this technology. But accordion to me it is better to go with instructor-led training for better understanding for that I will suggest you to go for Intellipaat which is offering the Artificial Intelligence Master Course in the market. This course is specially designed in collaboration with IBM for everyone so that anyone can learn it without prior knowledge as the training covers all the basic and advanced topics. During this training you will be learning various concepts of Artificial Intelligence. This program helps you to become an IBM certified professional.
