Mathematical Statistics (1) the mathematical foundation of statistics
- Discrete
- Continuous
Mathematical Statistics (2) statistical inference
- Point estimation
- Interval estimation
- Hypothesis testing
빅데이터란? 사이즈가 커진 것 뿐 아니라 그 타입이 다양해진 것 (including unstructured data)
Statistics
- Data collection
- Data analysis
- Inference and little bit of prediction
Machine learning
- Data analysis
- Prediction
In essence, machine learning is based on probability theory that mathematically expresses how likely something is.
Machine learning is a narrow field of Statistics.
머신러닝에서는 필요한 데이터를 최대한 크롤링해오는데, 크롤링된 데이터가 모집단을 어떻게 대표하는가에 대해서는 크게 신경쓰지 않는다. 또한 추론(inference)보다는 예측에 더 관심이 있다.
