round up to nearest hundred

Simply put, the K-nearest neighbor algorithm is classified by measuring the distance between different eigenvalue values.Advantages and Disadvantages Advantages High accuracy, insensitive to outliers, no data input assumptions. Disadvantages High computational complexity and high spatial complexity. Working with data ranges Numerical and nominal type. Example: Movi

given an array of integers, find a sub-array that is closest to zero. Returns the first and most of the indices. your code should return the starting and ending positions of the subarray that meet the requirementsSample ExampleGiven [ -3, 1, 1, -3, 5], return [0, 2],[1, 3], [1, 1], [2, 2] or [0, 4]challengesO (NLOGN) Time complexityAnalysis: First O (n^2) algorithm is very good to think, the direct lifting point on the line, see the complexity of the challenge, want to be sure to sort or two poi

Background In the clustering of large samples, because of the computational cost of K-means, some samples are randomly selected for clustering, and the clustering centers are obtained. However, it is often needed to get the nearest cluster center for each sample, which is commonly used in index construction, eg. OPQ (Pami 2014), inverted Multi-Index (Pami 2014). algorithm Steps Set a eigenvector p (1*2000), 2000 is a feature dimension. The cluster c

1. Background In the future, the blogger will update the machine learning algorithm and its Python simple implementation regularly every week. Today's algorithm is the KNN nearest neighbor algorithm. KNN algorithm is a kind of supervised learning classifier class algorithm. What is supervised learning and what is unsupervised learning? Supervised learning is the algorithm used when we know the target vector, unsupervised learning is used when we do

The following three scenarios are required to give a solution and resolve: 1: Two fork tree is the search binary tree. 2: Two fork tree each node has a parent (three fork chain) 3: It is the ordinary two-fork tree. (Achieve time complexity as O (N))For the first case, a binary search tree, we can determine the location of the two nodes according to the size of the data, if the root node is on the 2 side of the root node is the nearest public ancestor,

Each time you pass through an intersection, you need to pay a fee. The payment rule is that when his cash is greater than 50,000, he must pay 5% each time. If his cash is less than or equal to 50,000, he must pay 5,000 each time. Please write a program to calculate how
