ML (supervision, how generalized, on-off line learning) - Coggle Diagram

- - - - dimensionality reduction
        
        یعنی مثلا دوتا ویژگی بسیار با هم تغییر کنن پس یکی اضافیه
      - feature extraction
        
        متوجه یک ویژگی جدید از همبستگی چندتا بشی
    - - which the goal is to dig into large amounts of data and discover interesting relations between attributes
  - - - مثلا عكس رو بئوشوني و ماشين خودش حدس بزنه عکس چیه و بعدا از عکس کامل شده استفاده بکنه
  - - - regression
        
        the model will be asked to predict a value
        
        logestic reg
        
        multiple regression
        
        since the system will use multiple features to make a prediction
        
        uni/multi variate regression
        
        فقط یک یا چند چیز پیش بینی کنه
      - classification
        
        اینا گاهی یکی اند
        
        SGD classifiers = Online Gradient Descent
        
        SGD Classifier is a linear classifier (SVM, logistic regression, a.o.) optimized by the SGD
        
        SVM
- - - - utility function (or fitness function) that measures how good your model is
      - cost function that measures how bad it is
- - - - how fast they should adapt to changing data: this is called the learning rate
