DfT again understand 2015.12.18 Before learning "signal and system", for the use of FFT () function analysis of discrete, continuous time signal spectrum out of the result has been a smattering of knowledge, this semester learned "digital signal processing", learning the discrete Fourier transform (DFT), the previous written procedures to do further understanding. Before this, the CTFs, Dtfs, Ctft, DTFT for

Summary:Classification and Regression tree (CART) is an important machine learning algorithm that can be used to create a classification tree (classification trees) or to create a regression tree (Regression tree). This paper introduces the principle of cart used for discrete label classification decision and continuous feature regression. The decision tree creation process analyzes the information Chaos Measure Gini index, the special processing of c

modbus transaction. 　　 B. Coding of non-instruction data 　　 The most effective way to transfer large quantities of information on Modbus is to use function code 3 (read registers), 16 (write registers), or possibly 23 (read/write registers). 　　 Although these features are defined by their operation on a 16-bit register, they can transfer any type of information from one device to another, as long as the information is described in sections that are close to 16-bit instructions. 　　 The

The S function is short for system function. It is used to write its own Simulink module. (Simple enough, ^ _ ^. For more information, see help.) You can use MATLAB, C, C ++, Fortran, Ada, and other languages, here I will only introduce how to use the MATLAB language to write it (mainly because it is relatively simple). I will first explain why the S function is used. I think the S function can use the rich resources of Matlab, instead, it is not limited to the modules provided by SIMULINK, but

institutions teach this course will be less things. The less things now look at at least a random process. To graduate has not heard the Markov process, this is the computer department student's disgrace. How do you analyze networks and distributed systems without a random process? How to design randomization algorithms and protocols? It is said that Tsinghua computer department has "random mathematics", has long been a compulsory course. In addition, the theory of

In addition, discrete probability theory is applied to students in computer science.It has special importance. Our National Engineering Mathematics is about continuous probability.
