This is a hands-on TensorFlow learning repository with exercises spanning multiple AI domains. It includes basic neural network implementations (CNN, RNN), NLP models (LSTM, seq2seq with attention, chatbot), reinforcement learning algorithms (Q-learning, SARSA, DQN, Double DQN, Dueling DQN), and covers model saving, tensorboard visualization, and other ML training utilities. The repository is based on TensorFlow 1.4 and serves as a study guide for practitioners learning deep learning and reinforcement learning.
