Neuron — A math-based neuron simulate a little bit of bio-neuron
Layer — A chain of neurons usually function with the same context (input for output of previous layer)
Q-learning — A method of Reinforcement Learning using Bellman q-update (based on Bellman equation), Q-learning can use either q-table or q-network
Q-table — The original knowledge store used in q-learning, huge memory needed
Q-network — The modern knowledge store (params) in q-learning, very much memory efficient, as it learns by param combination instead of slots for all cases
Q-update — The formula for updating Q-value based on Bellman equation, Q += Rate x T, where T is temporal difference.
Q-value — Estimated sum of rewards from a state and taking a specific action
Q-function — The function which returns q-value, can be the q-table or q-network
Policy Network — A network in RL which returns suggested action instead of q-value
AI — Artificial Intelligence, with learning or no learning
ML — Machine Learning, the process of learning new things in AI
DL — Deep Learning, the method of ML using artificial neural network (ANN, neuralnet)
Bias — The param associated with each neuron to shift the separation line defined by weights
Weight — The param in a neuron for modifying input to neuron, and together with other weights and biases it makes the combination to comprehend left-most input
Loss Function — A convex function (parabola pointing downward) to minimize
