1. axis and argmax function

    简单讨论一下argmax函数及其用法，由于其在numpy和PyTorch中都有出现，所以先在numpy中讨论，然后补充介绍在PyTorch中的用法。

    同理我们可以理解argmin。

    Machine Learning Exercise 2

    实验题目

    1. Generate n = 2,000 points uniformly at random in the two-dimensional unit square. Which point do you expect the centroid to be?
    2. What objective does the centroid of the points optimize?
    3. Apply gradient descent (GD) to find the centroid.
    4. Apply stochastic gradient descent (SGD) to find the centroid. Can you say in simple words, what the algorithm is doing?

  3. 你也想要重来吗

    上了发条跟有节奏感是两码事

    上发条是走固定模式
    心已经在失控 行为看起来却没差

    有节奏感是由身心掌控
    有条不紊地 把握现在 感知未来

  6. LeetCode-Contest 103,104

    Contests From Contest103 to Contest 104 ~ Contest104 914-M 914. X of a Kind in a Deck of Cards In a deck of cards, each card has an integer written on it. Return true if and only if you can choose X >= 2 such that it is possible to split the entire deck into 1 or more groups of cards, where: Each group has exactly X cards. All the cards in each group have the same integer.
