However, there is still a lack of a powerful function, which is the fold function ). The so-called map-reduce, with map without "reduce" is not very disappointing? Next let's take a look at this "reduce". Reduce implementation The reduce mentioned above is actually a fold

1. Principle1.1 ConceptsCross-validation (cross-validation) is primarily used in model training or modeling applications such as categorical prediction, PCR, pls regression modeling, and so on. In the given sample space, most of the samples are taken as training sets to train the model, and the remainder of the sample is predicted using the newly established model, and the prediction error or prediction accuracy of the small sample is calculated, and their addition and averaging are recorded. Th

It consists of bubbles and graphs. The preparation of the bubble part is a little complicated. because there are many highlights, you need to use a pen or other selection tools to make the desired selection area, fill the color or fade, and use a mask to control the edge transition. Final effect 1. create a 800*800 pixel document with the background filled in blue. 2. select the elliptical tool, draw a circle on the background layer, fill in pur

Particle SystemIt is a two-dimensional image rendered in 3D controls, mainly used for smoke, fire, water drops, fallen leaves and other effects. A particle system consists of three independent parts: an example transmitter, a particle animation, and a particle Renderer. Some particle effects are included in unity. In assets> importpackage> particles, you can set the prticles. unitypackage is imported into the project. These particle effects include: dust, fire, water, smoke, and sparkles ), ther

Some time ago I saw a friend in the QQ Group asking me how to do the 3D Rotation effect of a group of images. Although I have seen this effect in the Flash version before, I have not done it myself. So I want to practice, and the final effect is as follows: In fact, this thing is to use the standard equation of the elliptic, And then you trigger an action at intervals through a dispatchertimer, so that the picture inside changes the coordinate point along the trajectory of the

During the competition, I jumped into this big pitfall and finally wrote the code. It seems that many of them are simulated annealing. Here is a strange idea. Ax ^ 2 + by ^ 2 + cz ^ 2 + dyz + exz + fxy = 1 (*) Through some strange YY, we can know that this is obtained by rotating a Standard Elliptical ax ^ 2 + by ^ 2 + cz ^ 2 = 1. The cross item exists because it bypasses X, y, Z axis rotation, so our idea is that we can know the shortest distance if

hrgn value can be obtained from the crgn class through the (hrgn) Force operation.Crgn provides the createrectrgn, createellipticrgn, and createpolygonrgn member functions for creating rectangular, (elliptical) Circular, and polygon areas respectively.The method for creating a non-rectangular window is as follows: first, define the area class member data (such as crgn m_rgnwnd) in the window class; secondly, call the createrectrgn, createellipticrgn,

In fact, there are only two kinds of geometric shapes: an elliptical shape (circular shape) and a Polygon Shape (having a certain number of edges ). A circle is an elliptical type with only one focal point. Triangles, rectangles, and Pentagons are polygon with different numbers of edges. A square is a type of rectangle with equal lengths of all edges. This constitutes a perfect inheritance relationship. In

): Render text. In addition to the above, the Canvas class can also depict text. Parameter 1 is String-type text, The parameter has two x axes, three y axes, and four is the Paint object. DrawOval(RectF oval, Paint paint): draws an elliptical image. The first parameter is the scan area, and the second parameter is the paint object; DrawCircle(Float cx, float cy, float radius, Paint paint): draws a circle. The first parameter is the X axis of the

"region" Object in MFC is implemented by the crgn class. Almost every crgn member function has an sdk api function with the same name. III,Simple "region" Creation A simple method for creating a new "region" using the crgn class includes the following member functions: Bool crgn: createrectrgn (INT X1, int Y1, int X2, int Y2); create the "region" of the rectangle ". Bool crgn: createellipticrgn (INT X1, int Y1, int X2, int Y2); Create a circular or ellip
