Zip() function is one of the builtin functions in Python. It can compress multiple sequences (list, tuple, dictionary, set, string and range() interval) into a zip object. The socalled “compression” is actually to recombine the elements at the corresponding positions in these sequences to generate new tuples. Unlike Python 3. X, the zip() function in […]

Link to the original text:http://tecdat.cn/?p=20335 In this paper, we will introduce three advanced techniques to improve the performance and generalization ability of recurrent neural networks. We demonstrate three concepts for temperature prediction, using time series of sensors on the roof of a building. summary In this paper, we will introduce three advanced techniques to improve […]

An algorithm is designed to judge whether the brackets in the expression are paired. The (stack) data structure is the best. Parsing: judge each character in the expression in turn. If it is left bracket, it will enter the stack. If it is right bracket, it will exit the stack. When leaving the stack, judge […]

By combiningARIMAandGARCHModel, in the long run, we can go beyond the “buy and hold” approach. Strategy overview The strategy is implemented on the basis of “rolling” prediction For each […]

Link to the original text:http://tecdat.cn/?p=20424 introduce Time series provide a method for forecasting future data. Based on the previous values, time series can be used to predict economic, weather trends. The specific attributes of time series data mean that special statistical methods are usually needed. In this tutorial, we will first introduce and discuss the […]

Let’s consider some time series)For example, traffic flow on the road, > plot(T,X,type=”l”) > reg=lm(X~T) > abline(reg,col=”red”) If there is a trend, we should delete it and deal with the residuals > Y=residuals(reg) > acf(Y,lag=36,lwd=3) […]

Link to the original text:http://tecdat.cn/?p=20953 preface This paper demonstrates the application of DLMS and dlnms in time series analysis. Gasparrini et al. [2010] and Gasparrini [2011] described the development of DLMS and dlnms and the realization of time series data. The examples described in this paper cover most of the standard applications of dlnm methods […]

1、 RNN overview The assumptions of artificial neural network and convolutional neural network are as followsThe elements are independent of each otherBut in many cases of life, this assumption does not hold, such as you write a meaningful paragraph“It takes only one second to meet someone, three seconds to like someone, and one minute to […]

The iterator makes the algorithm independent of the container, but the algorithm depends on the operation of the element type. Algorithms never perform container operations. The algorithm never changes the size of the underlying container. accumulateIt is defined in the header file numeric and accepts three parameters. The first two indicate the range of elements […]
