Is there a visualization framework like JUNG for iOS?

阅读更多关于 Is there a visualization framework like JUNG for iOS?

问题 Is there a visualization framework like JUNG for iOS? I'd like to implement something similar to this. 回答1: Best graph plotting library for iOS is Core plot. It is very powerful, and easy to understand. But for simple graphs you can use s7graphview library also. If you want to do it yourself, you can do custom drawing using Core graphics. 来源： https://stackoverflow.com/questions/5758625/is-there-a-visualization-framework-like-jung-for-ios

I have a pass traffic data between players, here's the data , first column and first row indicate the Player Numbers. I want to visualize this data like Uber Rides . I think it was built with Chord Diagram from Bostock's. Since I almost have no experience in JavaScript, I just don't know where to begin. How can I achieve something like this? Here is what i got with your data I just replaced the matrix array with your array [2,3,1,0,0,2,0,6,5,2,5,0,3], [0,7,2,0,4,7,0,1,2,0,3,0,2], [0,0,4,1,5,3,3,0,1,1,5,1,0], [0,0,0,0,4,0,5,4,2,0,1,1,0], [0,0,0,0,0,0,0,3,2,0,1,0,1], [0,0,0,0,0,1,3,4,1,1,9,1,6],

How to visualize TensorFlow Estimator weights?

阅读更多关于 How to visualize TensorFlow Estimator weights?

问题 How can I select a layer from a tf.estimator.Estimator and access the weights vector for each unit in that layer? Specifically, I'm trying to visualize a Dense layer's weights. Looking at https://github.com/tensorflow/tensorflow/blob/r1.3/tensorflow/python/layers/core.py it seems that the weights are called kernels , but I'm not able to access those when using the Estimator abstraction. Ps: for an example of an implementation of Estimator, let's reference https://www.tensorflow.org/get

Visualizing data on geographic map with networks (R)

阅读更多关于 Visualizing data on geographic map with networks (R)

问题 I am trying to depict a network on the geographic map using data contained in a cultural distance matrix. E.g.: AT BE CH CZ AT 0 0.00276 0.148 0.109 BE 0.00276 0 0.145 0.112 CH 0.148 0.145 0 0.257 CZ 0.109 0.112 0.257 0 Starting and ending points of the network’s lines should be located in different countries (i.e. here AT, BE, CH and CZ). Lines should be depicted between countries when a corresponding entry of the matrix is below a certain threshold (e.g., the mean of all matrix’ entries).

How can I implement a linear regression line in a Vizframe Chart?

问题 I have a scatter plot Vizframe chart in which I need to include a linear regression/trend line. Any idea how this can be done? It appears this is not something offered by vizframe 'out of box'? I can't find a solution for this! Question: Any suggestions on a feasible way to implement a regression line on a Scatter Plot Vizframe chart? Here is the code I have for the setup. The scatter plot opens in a dialog/modal when a button is pressed. sap.ui.define([ 'jquery.sap.global', 'vizConcept

How to display the path of a Decision Tree for test samples?

阅读更多关于 How to display the path of a Decision Tree for test samples?

问题 I'm using DecisionTreeClassifier from scikit-learn to classify some multiclass data. I found many posts describing how to display the decision tree path, like here, here, and here. However, all of them describe how to display the tree for the trained data. It makes sense, because export_graphviz only requires a fitted model. My question is how do I visualize the tree on the test samples (preferably by export_graphviz ). I.e. after fitting the model with clf.fit(X[train], y[train]) , and then
