Logistic Regression Advantages: low computational cost, easy to understand and implement. Disadvantages: it is easy to under fit, and the classification accuracy may not be high. Applicable data types: numerical data and nominal data. Main idea: according to the existing data, the classification boundary resume regression formula is used to ...

Pre knowledge: related terms of graph and representation of graph Traversal of Graphs Similar to the tree data structure, we can access all nodes of the graph. The graph can be traversed by two algorithms: breadth first search (BFS) and depth first search (DFS). Graph traversal can be used to find a specific vertex or the path between two ver ...

Yang Hui triangle Topic introduction Train of thought analysis First of all, we need to understand how the Yang Hui triangle was formed. As shown in the figure, the beginning and end numbers of each layer are 1, and the number of each remaining position is equal to the sum of the number of the corresponding position of its upper laye ...

** Preface: prepared by Golang leetcode Title: 162 Find peak Binary decomposition method: time complexity: O(log n), space complexity: O(1) Logic Description: When looking for the peak, because the title says that just look for one. And nums[-1] and nums[len (nums)] are expressed as negative infinity, so the following situations can be cons ...

Question 1: Roman numerals to integers Roman numerals contain the following seven characters: I, V, X, L, C, D and M. Character value I  1 V  5 X  10 L   50 C 100 D 500 M 1000 For example, the Roman numeral 2 is written as II, which is two parallel ones. 12 is written as XII, which is X + II. 27 is written as XXVII, which is XX + V + II. Usual ...
