          When fitting a model to the data, there is a tradeoff between bias and complexity. A less biased model can have higher complexity, but this also makes it more prone to overfit. In contrast, with more bias, the model is limited to simpler problems. We explain this phenomenon with python examples in both classification and regression examples.

          We derive Hoeffding's inequality. This is one of the most used results in machine learning theory.
