TINTOlib
TINTOlib is a state-of-the-art library that wraps the most important techniques for the construction of Synthetic Images fromTidy Data (also known as Tabular Data).

Documentation
Getting Started
You can install TINTOlib using Pypi:
pip install torchmetrics pytorch_lightning TINTOlib imblearn keras_preprocessing mpi4py
To import a specific model use
from TINTOlib.tinto import TINTO
Create the model. If you don't set any hyperparameter, the model will use the default values (read documentation).
model = TINTO(blur=True)
To generate the synthetic images use .generateImages(data,folder) method.
model.generateImages(data, resultsFolderPath)
How to use TINTOlib - Google Colab crash course
Once the images have been created by TINTO, they can be imported into any project using CNNs.
In order to facilitate their use, a Jupyter Notebook has been created in which you can see how the images are read and how they can be used as input in a CNN.

Converting Tidy Data into image
For example, the following table shows a classic example of theIRIS CSV dataset as it should look like for the run:
| sepal length | sepal width | petal length | petal width | target |
|---|---|---|---|---|
| 4.9 | 3.0 | 1.4 | 0.2 | 1 |
| 7.0 | 3.2 | 4.7 | 1.4 | 2 |
| 6.3 | 3.3 | 6.0 | 2.5 | 3 |
Simple example without Blurring
The following example shows how to create 20x20 images with characteristic pixels, i.e. without blurring. Also, as no other parameters are indicated, you will choose the following parameters which are set by default:
- Image size: 20x20 pixels
- Blurring: No blurring will be used.
- Seed: with the seed set to 20.
More specific example
The following example shows how to create with blurring with a more especific parameters.
The images are created with the following considerations regarding the parameters used:
- Blurring (-B): Create the images with blurring technique.
- Dimensional Reduction Algorithm (-alg): t-SNE is used.
- Blurring option (-oB): Create de images with maximum value of overlaping pixel
- Image size (-px): 30x30 pixels
- Blurring steps (-sB): Expand 5 pixels the blurring.
