Python uses support vector machine regression (SVR) model to analyze power consumption and predict power consumption
Original link: http://tecdat.cn/?p=23921 This paper describes the process of training support vector regression model, which is used to predict power consumption based on several weather variables, an hour of the day, and whether the day is weekend / holiday / home working day or ordinary working day. Fast description of support vector machine Support vector […]

79 sequence traversal of complete binary tree (25 points)
Click to view the title 79 sequence traversal of complete binary tree (25 points)A binary tree is a perfect binary tree if the number of nodes in each layer reaches the maximum. For a binary tree with depth D and N nodes, if its nodes correspond to the first n nodes of the sequence traversal […]

R language arimagarch volatility model predicts the daily return time series of apple in the stock market
Original link:http://tecdat.cn/?p=23934 introduction In this paper, we will try to find a suitable GARCH model for Apple’s daily return. Volatility modeling requires two main steps. Specify a mean equation (e.g. ARMA, AR, Ma, ARIMA, etc.). Establish a volatility equation (such as GARCH and arch, which were first developed by Robert Engle). To do (1), you […]

Increase decrease sequence
Increase decrease sequence The ultimate goal is to make the whole sequence equal There is only one operation to make\([l,r]\)Interval all\(+1\) Since the whole sequence is equal, theDifferenceSequence should be 0 Operation can be transformed into\(a[l]+=1，a[r+1]=1\) The minimum number of operations is required Through the original sequence, we first find an original difference sequence, and […]
