An ontology was used, with a hierarchy of concepts (for example object->person->human), and a database of instances of those objects (for example the Player is a human).

This allowed for some generalizations, for example expecting that all Persons has a favorite color.
This was inspired in the work on Ontological Semantics

The system also uses an utility function to select the answers, given a set of goals.
This was inspired by the Versu story engine.

Illusion of life, by Software - 2017

This work discusses theoretical concepts about how to build systems that can convey the illusion of life.

Style Transfer - 2016

Style transfer is a technique that allows to separate the information about the content and the style from an image. This is achieved training a neural network on classification and latter separate the information stored on low level and high level neural network layers.

Transferring style

The original idea of the algorithm is to take the style of one image and transfer it into another, maintaining the content.

To test the system I used a photograph and a drawing of woods

This image have the content of the photograph, and the style of the drawing

Color Grading Transfer

I decided to extend this technique to transfer the Color Grading from a picture to another.

Color grading transferred to Davy Jones

Color grading transferred to Gollum

Lighting Transfer

Also we can transfer the lighting from a picture to a 3D scene.

The source of lighting can be a drawing!

Color Scheme Generator - 2016

This projects uses machine learning to generate color schemes similar to the used by Jean Francois Painchaud (NSFW).

I analyzed about 150 images in order to extract colors for Skin, Lips, Hair, Background (including Shadows, Midtones and Light).

Some examples of generated color schemes

ZombieAI

A game that aims to demonstrate Q-Learning, a Reinforcement Learning technique (Artificial Intelligence).

The user configure the algorithm allowing ZombieAI to learn to walk to the brain without falling in a trap.

Pianist Animation Generator - 2018

The goal of this project is to generate the animation of the pianist directly from a MIDI music file.
The main issue is to determine what finger to use for each note on a specific time.

If a pianist must play 10 notes at once she or he have 9,090,909,090 different possible fingers combinations available! (supposing that the fingers can be arranged in any order)

Keys, Possibilities
1: 10
2: 90
3: 910
4: 9,090
5: 90,910
6: 909,090
7: 9,090,910
8: 90,909,910
9: 909,090,910
10: 9,090,909,090

DQL works great for one finger. But for more fingers I switched to Evolutionary Algorithms, where heuristics can be used to simplify the problem.
