Neural network for data visualization
At my work, we're currently doing some research into data visualisation for highly interconnected data, basically graphs.
We've been implementing all sorts of different layouts and trying to see which fits best, but, due to the nature of the problem…

How to graphically represent a RNN architecture implemented in Keras?
I'm trying to create a simple blogpost on RNNs, that should give a better insight into how they work in Keras. Let's say:
model = keras.models.Sequential()
model.add(keras.layers.SimpleRNN(5, return_sequences=True, input_shape=[None,…

How do AI researchers imagine higher dimensions?
We can visualize single, two, and three dimensions using websites or imagination.
In the context of AI and, in particular, machine learning, AI researchers often have to deal with multi-dimensional random vectors.
Suppose if we consider a dataset of…

Is it possible to reconstruct convolutional layers' input using transposed convolution?
I've been trying to visualize internal activations in CNN and came across this paper: "Visualizing and Understanding Convolutional Networks" by Zeiler & Fergus.
In the paper they mentioned reconstructing the input image from internal convnet…

Do researchers generally treat tensors just as mathematical objects with certain shape?
Most of the practical research in AI that includes neural networks deals with higher dimensional tensors. It is easy to imagine tensors up to three dimensions.
When I ask the question How do researchers imagine vector space? on Mathematics Stack…

How to visualize the images?
Suppose we have 24 images per day, one per hour. And every image is 24×24 CSV file.
I do the following transformation for every day:
The first image is unchanged.
For the second image, move
column i to (i+2) mod 24.
For the third image, move…

How do I plot a matrix of ratings?
I have a .csv file called ratings.csv with the following structure:
userID, movieID, rating
3, 12, 5
2, 7, 6
The rating scale goes from 0 to 5 stars. I want to be able to plot the sparsity of the matrix like it's done in the…

Easiest way to visualize decision boundary of Heaviside Networks
In my Class/Exam there are a lot tasks where the goal is to draw the decision boundary of a Heaviside based Neural Network.
An example of this is:
Problem:
For the given neural Network, sketch the decision boundary (the area of Points in R^2 that…
