Machine Learning formula derivation and analysis
All the contents of the Pumpkin Book are expressed with the content of the Mr. Zhou Zhihua's "Machine Learning" Watermelon Book as the pre-knowledge, so the best way to use the Pumpkin Book is to use the Watermelon Book as the main line. Please refer to it when you encounter a formula that you cannot derive or cannot understand. We strive to explain and derive each formula from the perspective of undergraduate mathematics.
