Google Chart Sankey Diagram online for non software developers

I saw lots of tutorials of how to create a Sankey diagram but I couldn't find a quick way to see my data without installing or configuring parameters. Thus, here I present a Sankey Diagram to visualize your data. In case you are a software developer this may result to be something simple for you, but in case you don't have programming skills but want a Sankey diagram, this post is for you.

You have to upload a CSV file, comma separated in the format:

NodeA, NodeB, Weight

An example of a CSV file could be:

Root A,Branch X,3
Root B,Branch X,8
Root B,Branch Y,2
Root B,Branch Z,3
Branch X,End 1,19
Branch X,End 2,2
Branch X,End 3,4
Branch Y,End 1,10
Branch Y,End 4,17
Root B,Branch ZX,4
Branch ZX,End 1,1

This will create the following Graph:

Instructions of use:

Way one

  1. Click on Chose File and search for your CSV file.
  2. In the text field you will see your data loaded. You should see "NodeX1,NodeY1,N1;NodeX2,NodeY2,N2...
  3. Click in the button Process
  4. If you want to load a new csv file with the same name as the previous file, you should reload/refresh/F5 the webpage. (The code have some limitations at the moment)

Way two


  1. In the input text field write a line with the format NodeX1,NodeY1,Number1;NodeX2,NodeY2,Number2;...;NodeXN,NodeYN,NumberN
  2. Click in the button Process
  3. Notice that the input text line should finish in a number, not in a ";". Each";" represents a new link of the previous NodeX, NodeY, Weight.

Deep neural networks visualization

Imagen
In this publication I present a "toy tool" to see how neurons on a Deep Neural Network (DNN) modify the links between them. These links are also called Weights. For those with technical knowledge, the "bias" unit is not shown (Because of lack of time, I will upgrade it later). In addition I haven't implemented yet the predict option, I would probably add it later. Technical Notes: This DNN uses standard back propagation without optimizations such as Adam optimizer or regularization parameters.   I am using Math.js  for the matrix operations. There are some errors I haven't figured out yet how to solve them, specially for Nan values that will appear when showing the visualization (Sometimes happens, no worry =) ) The last layer, the output layer is a sigmoid layer by default. Maybe later I will implement a linear function for regression analysis. And it has been implemented for binary classification by the moment. The weights are randomly init...

Tensorflow Batch norm not working

Have you experienced that when using  tf.contrib.layers.batch_norm during test time, the performance is diminished or is completely a mess? If yes, this post is for you. Quick summary: 1) As suggested in [1]:   you have do add this additional code:   update_ops = tf . get_collection ( tf . GraphKeys . UPDATE_OPS )   with tf . control_dependencies ( update_ops ):     train_op = optimizer . minimize ( loss ) 2) You have to use a placeholder to indicate that you are training or not, so you put this in the batch_norm param  is_training = your_place_holder, True for training. 3) If after this it doesn't show a good behavior, change the default  decay = 0.999, to a lower value such as  0.5. Other way to apply batch norm is presented in [2], for a manual setup. Nonetheless, if by using this second approach you still have a bad performance, use the point 3). If you want to use this second approach with Convolutional Neural Netw...
