[CrashCourse CS] #34 Machine Learning & Artificial Intelligence

Machine Learning

Algorithms that give computers the ability to learn from data, and then make predictions and decisions.

Classification - Classfier (algorithm)
Features - Values that usefully characterize the things we wish to classify

• traning data, labeled data
• find optimal separation
• confusion matrix

• Artificial neural networks: deep neural nets
  
  

Weak AI, narrow AI - only intelligent at specific tasks (self-driving, face detection, etc.)
Strong AI - general-purpose AI (not yet invented)

AlphaGo - Reinforcement Learning: playing clones of itself millions of times

Vocabulary

• arrhythmia - 부정맥
• fiendish - 골치아픈, 어려운

Thoughts

Artificial neurons 의 작동원리는 사실 설명을 들어도 어떻게 작동하는건지 잘 모르겠다. 하지만 저걸 잘 활용하면 여러 분야에 활용할 수 있을 것 같다.
