is, the value of P (B | ). 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: >>> From sklearn import datasets # import data in the package >>> iris = dat

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

The calculates the maximum, average, median, and mean variance of the iris petal length. from sklearn.datasets import load_irisimport numpy as Npiris = Load_iris () print (Iris) Petal_length=np.array (list (len[2]for len in iris[' data ')) Np.max (petal_length) #花瓣长度最大值np.

double color temperature flash testHow to see the effect of double color temperature flash testNow let's get back to the point of seeing if the dual-color-temperature Flash has the effect of correcting the white balance compared to a normal flash. The author chooses two mobile phones (model please self-repair), one for dual LED flash another is a two-color temperature flash, in the dark indoor and effective flash distance shooting near objects. the first photo in each of the following groups co

classifier.expectedTo indicate 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 Not to mention, go directly to the code, and then expla

. 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: # The helloworld of the decision tree uses the decision tree to classify the iris
