transformation

问题 I have below input JSON : { "id": "2ef8a2ee-054f-4b43-956a-8aa4f51a41d5", "type": "VOICE", "tags": [ { "id": "some id 1", "description": "some description 1" }, { "id": "some id 2", "description": "some description 2" } ], "transcription": { "key1": "val1", "key2": "val2" } } But, output JSON should look like similarly, and add only default values: { "id": "2ef8a2ee-054f-4b43-956a-8aa4f51a41d5", "created": "2019-06-18T18:12:37", "firstName": "Khusan", "lastName": "Sharipov", "status": "OPEN"

问题 I've made the following code: #include <math.h> #include <GL/gl.h> #include <GL/glu.h> #include <GL/glut.h> #define WIDTH 400 #define HEIGTH 400 #define ORIGIN_X 50 #define ORIGIN_Y 50 #define move(x,y) glTranslatef(x, y, 0.0f); #define enlarge(y) glScalef(1, y, 1); #define rotateX(angle) glRotatef(angle, 1,0,0); #define rotateY(angle) glRotatef(angle, 0,1,0); #define rotateZ(angle) glRotatef(angle, 0,0,1); // Variables que definen la rotación del brazo entero (de hombro a mano) static

问题 I have a table that looks as follows ID | value1 | value2 | value3 1 | 5 | 6 | 7 2 | 10 | 11 | 12 3 | 20 | 21 | 22 I need to create one row for each of the 3 value columns per ID . The final table should look like this (the column headers dont make sense anymore, but you can ignore this): ID | value1 | value2 1 | value1 | 5 1 | value2 | 6 1 | value3 | 7 2 | value1 | 10 2 | value2 | 11 2 | value3 | 12 3 | value1 | 20 3 | value2 | 21 3 | value3 | 22 What would be the best way to approach this

问题 I'm currently working on a game which renders a textured sphere (representing Earth) and cubes representing player models (which will be implemented later). When a user clicks a point on the sphere, the cube is translated from the origin (0,0,0) (which is also the center of the sphere) to the point on the surface of the sphere. The problem is that I want the cube to rotate so as to sit with it's base flat on the sphere's surface (as opposed to just translating the cube). What the best way is

问题 My question is: How can I transform a Data Frame like this to eventually use it in scikit's MulitLabelBinarizer: d1 = {'ID':[1,2,3,4], 'km':[80,90,90,100], 'weight':[10,20,20,30], 'label':['A','B','C','D','E']} df1 = pd.DataFrame(data=d1) df1 ID km weight label 0 1 80 10 A 1 2 90 20 B 2 2 90 20 C 3 4 100 30 D It should tourn ot like this: d2 ={'km':[80,90,100], 'weight':[10,20,30], 'label':['A',('B','C'),'D']} df2 = pd.DataFrame(data=d2) df2 km weight label 0 80 10 A 1 90 20 (B, C) 2 100 30 D

问题 I would like to do cross validation for 5 folds. In each fold, I have a training and valid set. However, due to data issue, I need to transform my data. First, I transform the training data, train the model,apply the transformation rule to the validation data, and then test the model. I need to redo the transformation for every fold. How would I do that in H2O? I can't find away to separate the transformation part out. Does anyone have any suggestion? 来源： https://stackoverflow.com/questions

问题 I have two points that I want to connect in a specific way - see the first picture. I know the coordinates of all four points. I then need to move the whole shape to coordinates [0, 0] and rotate it, so the main two points are both on x-axis (see the second picture). Next I need to "squeeze" the shape on the x-axis only so that the last point has coordinates [0, 1] (see the last picture). My question is - how do I compute the coordinates of the middle two points effectively in Java without

问题 I have tried this: g.RotateTransform(degrees); But nothing happens.I have one graphics object and one rectangle object witch im drawing using this method: g.FillRectangle(new TextureBrush(Image.FromFile(@"D:\LOVE&LUA\Pictures\yellowWool.png")), rectangle); And i need to rotate the rectangle somehow and draw it again. Answer with code sample please and with a simple explanation. EDIT: Here is the actual code I'm using: public void Draw(Graphics g,PointF location,Color clearColor) { rectangle

问题 I need an open-source tool which can convert POJOs to XML and JSON strings. Jersey (and probably other JAX-RS implementations) would fit these requirements if mappings could be configured through xml-files but not through annotations. Is there anything suitable? 回答1: POJO to XML JAXB is the Java standard (JSR-222) for converting Java objects to/from XML (I am a member of the JAXB expert group): http://bdoughan.blogspot.com/2010/07/jaxb-xml-binding-standard.html POJO to JSON People have been

问题 I would like to draw scaled objects containing raster as well as vector data. Currently, I am drawing into a scaled Graphics2D object protected void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g.create(); //Get transformation, apply scale and shifts at = g2d.getTransform(); at.translate(x, y); at.scale(zoom, zoom); //Transform Graphics2D object g2d.setTransform(at); //Draw buffered image into the transformed object g2d.drawImage(img, 0, 0, this); //Draw
