, let's take the actual data to test it. Data set one is the data set of iris stamens, and the other is missing because of the record, so I don't know what the data is about ...Iris stamens part of the data, there are three different categories:Unknown data set, the decimal point is a comma, so you need to deal with the calculation:We'll deal with the unknown data set first. First, the file name of our unna
high. Disadvantage: In the process of constructing the tree, the data sets need to be scanned and sorted several times, resulting in inefficient algorithm. 5. Code implementation The code runs in the R language on the dataset Iris, as long as the three installation packages "Rweka", "Party", "Partykit" are installed first. That is, run the following code: Then run the following example code: Code and result analysis: Code 6, The 7,8 load pa
Such a feature has only 0 and 12 values, and the dataset has three categories. When taking 0, if the category A has 20 such individuals, category B has 60 such individuals, category C has 20 such individuals. Therefore, this feature is 0 o'clock, most likely the Class B, but there are still 40 individuals are not in category B, so the error rate of 0 points to Category B is 40%. Then, all features are counted, all feature error rates are computed, and the lowest error rate is selected as the onl
Proximity algorithmOr, K nearest neighbor (Knn,k-nearestneighbor) classification algorithm is one of the simplest methods in data mining classification. The so-called K nearest neighbor is the meaning of K's closest neighbour, saying that each sample can be represented by its nearest K-neighbor.About k nearest neighbor algorithm, a very good article: KNN algorithm understandingIndustry applications: Customer churn prediction, fraud detection, etc. (more suitable for classification of rare events
This section learns to use Sklearn for voting classification, see a specific example, the dataset uses the Iris DataSet, using only the sepal width and petal length two dimension features, Category we also only use two categories: Iris-versicolor and Iris-virginica, the standard uses ROC AUC.Python Machine learning Chinese catalog (http://www.aibbt.com/a/20787.ht
dirty, these stains and spots will distract attention, so also to eliminate. The Healing Brush tool is used here.
6, adjust the Puppy eye section below. Add a new layer, named "Black Eyes", the use of soft black brush, the eye peripheral darkened. It looks a little scary now, but it's good to be back.
7, select the Pen tool, draw a crescent-shaped, and then fill the brown #c07c3e. The outline of the new Iris is not too much
even getting them bigger.
The eye is understood to be composed of four elements of pupil, Iris, white and eyelash, which is very useful for trimming eyes. Each element requires a different set of tools. Increase the hue inside the iris, darken the pupil and iris edges, lighten the white light and sharpen the eyelashes. The tricky thing here is not to be afraid
popular 3D API. In fact, OpenGL is longer than DirectX, compared to DirectX can only be applied to Microsoft's platform, OpenGL can be applied to many different operating systems. Currently, most Linux 3D acceleration games are all OpenGL, so for Nvidia's latest driver, only small changes can be adapted to most games. The 3D API under Linux is based on OpenGL. OpenGL is a professional 3D program interface, is a powerful, easy to invoke the bottom of the 3D graphics library. The predecessor of O

What about the new MacBook Pro solo dominance?
The MacBook Pro product update, in addition to the appearance of the adjustment (more frivolous), the configuration is also upgraded, of which "low match" (13-inch also got 11488 yuan) the nuclear screen is Iris 540/550, while the high match is AMD Radeon Pro 450 Graphics (13 inch) and AMD Radeon Pro 455/460 Graphics Card (15 inch).

Fourth Step
Draw a smaller circle above the eye layer called the iris. Double-click the IRIS Layer color icon to change it. I prefer green, but it doesn't matter. Add inner Shadow, inner glow (glow, translation flare), bevel and emb
This article focuses on shadows/highlights and curves, and, well, a little bit of smart objects.
By changing the contrast and the black and white adjustment layer, you can learn a technique that converts an image into a hand-drawing effect.
The end result looks like a hand drawing, and then a more rustic hand-drawn feeling is created by fine-tuning the brush.
01. Enhanced Contrast
First, download the source file, and then import the image. To highlight this important area of the

Last article we looked at the happy Yellow , now turn to yellow complementary color-purple. The unpleasant thing is, purple is easy to see the top, but the good words can be very eye-catching and fashionable. View the color plate we can see that purple is the intersection of Red and Blue , and there are many transi
