To facilitate learning and test various content in machine learning, sklearn has a variety of built-in useful datasets, such as text processing and image recognition.
The problematic data is collected in sklearn (user-friendly for beginners ).
The IRIS data set for KNN described in this article can also be used in sklearndatasetsModule.KNN algorithm implementation

. In data mining, we often use decision trees for data classification and prediction.
Helloworld of decision tree
In this section, we use decision trees to classify and predict iris data sets. Here we will use graphviz of the tree under sklearn to help export the decision tree and store it in pdf format. The Code is as follows:

In the last section we introduced how to draw the big eyes of the cartoon beauty , next we will draw the handsome man's eye, see what characteristic of male's eye.
The average male character will be overlooked by comic-book enthusiasts, because many draw friends think men are more difficult to draw. In fact, it is not so "difficult" problem, although the difference between the two is indeed relatively large. Most men's eyes are thinner and narrower than those of women.Start drawing a thick, r

Erase the auxiliary line and draw a long oval in the eye. There are also some comic characters whose Iris (the eyeball) is a large circle, but here we draw it into a slender oval, of course you can adjust the shape to suit your liking. The upper pa

2X ^ TXw-2X ^ Ty = 0
X ^ TXw = X ^ Ty
If X ^ TX is full, it is reversible. Therefore, the left side of both sides is multiplied by (X ^ TX) ^-1 at the same time.
Therefore:
W = (X ^ TX) ^-1) X ^ Ty, that is, the preceding result.

3. three common naive Bayes algorithms are provided in the scikit-learn package. The following describes them in sequence:
1) Gaussian naive Bayes: assuming that attributes/features are normally distributed (for example,), they are mainly used for numeric features.
Use the data in the scikit-learn package. the code and description are as follows:

computer receives an ARP response packet, it updates the local ARP cache and stores the IP and MAC addresses in the response in the ARP cache. Therefore, if someone sends a self-built ARP response in the network, the network may be faulty. This is ARP spoofing. A common feature of ARP spoofing is that the host is frequently disconnected.
Our network symptoms are very similar, but ARP attacks need to find its source. The general method is hard to find and packet capture analysis needs to be perf
