machine learning

supervised learning

• 학습을 시킬 때 label에 정답이 있는 것
• Need input, target
• Learning from difference between prediction and target
• e.g. mnist, classification

unsupervised learning

• label 이 미리 정해져 있지 않은 것
• Need input
• Cluster by distance between inputs
• Can't predict outcome
• e.g. clustering

reinforcement learning

• 일종의 unsupervised learning
• input : environment, reward, output : action
• Learn from try
• Model free
• e.g. game play, stock trading

reinforcement learning

• Q learning
• Neural Network
• DQN : Deep Q Learning
