Today most commonly used Artificial Intelligence tools are TensorFlow, PyTorch, CNTK, Caffe, Apache MXNet, Keras, OpenNN, AutoML, and H2O.ai. Each tool is used for different purposes, and choosing the right one depends on the task you are trying to accomplish. For example, TensorFlow is one of the most popular tools for deep learning, while AutoML is used for automating machine learning processes. I have used TensorFlow with IBM’s Watson Studio.
