João Afonso Batista's Projects

advanced-agorithms-1

1st year master project: Implementation, in C, of the Knuth Morris Pratt and the Boyer Moore algorithms for finding strings in texts. (no documentation))

advanced-agorithms-2

1st year master project: Create a suffix tree to find the longest substring common to N texts

3rd year bachelor project: Developing agents playing the boardgame "Scotland Yard". 3 agents have to find optimal paths to traverse the board, having a limited number of taxi, bus and train tickets. (Documentation in Portuguese)

artificial-inteligence-2

3rd year bachelor project: Developing agents playing the boardgame "Scotland Yard". 1 agent learns, through reinforcement and exploratary learning which places on the board to avoid. (Documentation in Portuguese)

bachelor-final-project

3rd year bachelor final project: A proof-search algorithm for non-classical logics (project in Portuguese)

complex-networks

1st year master project: Game theoretical simulation that studies the evolution of strategies and the existance of coorperation when individuals have initial variability, in the form of honesty and charisma. (Documentation in Portuguese)

criptography

3rd year bachelor project: Implementation the "Honest-but-Curious set intersection" cryptograpic system, where n people, each one with a set C_i, comunicate with each other in such a way that, after comunicating, everyone knows the interception of every set C_i, without gaining any further information about the set of other people. (Documentation in Portuguese) (GitHub can't read mathematica/wolfram notebooks)

data-mining-1

1st year master project: unbalanced supervised classification problem: prediciting whether a patient will suffer a Myocardial Rupture. data preprocessing with missing value analysis, outlier analysis, dimentionality reduction and oversampling. Training a lot of classifiers, K-Nearest Neighbour, Binary Logistic Regression, Naive-Bayes, Support Vector Machines, Linear Discriminant Analyses, Linear Discriminant Analyses on Expanded Basis, Quadratic Discriminant Analyses, Decision Trees and Neural Networks.

data-mining-2

1st year master project: Unsupervised classification problem, prediciting whether a patient will suffer a Myocardial Rupture.: Clustering the data points using various methods, namely, Hierarchical Clustering, Partition Clustering, Density-based Methods, Graph-based Methods and Spectral analysis. Then, use the classes found by the clusters to train a Support Vector Machine to classify new data points..

data-visualization

1st year master project: A Visualization of the olympic games data. (olympic_games.js is the main script)

databases-project

3rd year bachelor project: Setup of a dummy database and setup of a PHP web application (Documentation In Portuguese)

fantasy-type-adventure

Game I developed in my free time. Both as a way to test my programing skills, develop them and produce something I could be proud of. At the moment it only has the first version, equiped with 9 toturial levels. A second version with sound, more abilities and the begining of a storyline is being developed. (Fantasy Type Adventure.py is what is supposed to be run)

linear-and-non-linar-optimization

1st year master project: Projection of a 10-dimentional dataset into 2 or 3 dimentions using the Levenberg–Marquardt optimization algorithm, which was implemented.

multiagent-system

1st year master project: A simulation of a rover exploring the surface of Mars using a multiagent system

multivariate-analises

1st year master project: Analysing data from the "World Hapiness Report" using multivariate techniques.

numerical-analysis-1

3rd year bachelor project: Increase the resolution of images using interpolating surfaces (Documentation in Portuguese)

numerical-analysis-2

3rd year bachelor project: Calculate planet trajectories and rocket orbits using methods to approximate differential equations (Documentation in Portuguese). Methods used: 4th order Runge-Kutta, 4th order Adams-Bashford and Variable step Bogacki-Shampine

programing-elements

1st year bachelor project: Simulation for a chemistry engine. Hidrocarbonate molecules can evaporate, separate or combine depending on the temperature throughout time. can (Documentation in Portuguese)

time-series

1st year master project: Analyze and forecast/predict the daily average density of PM10 particles in the atmosphere in a region of Lisbon using, Time Series related techniques.
