machine learning book notes #
types:
- supervised learning (right solutions given)
- unsupervised learning (no solutions given)
- reinforcement learning (reinforce beahviour according to feedback)
supervised learning problems:
classification (X is a … basend on Y)
regression (attribute Z of X is … based on >)
nearest neighbour (to which Y is X most similiar)
overfitting (model works much better on trainingdata than testdata)
underfitting (model is too weak to reproduce even trainingdata results)
choice of features is crucial. less might be better bc less dimensions
good, clean training data is crucial.
