Applying Data Mining Techniques to Breast Cancer Analysis, April 2011
- Course: Knowledge Extraction and Machine Learning
- Description: Fine Needle Aspirate (FNA) is a diagnostic procedure used to investigate superficial lumps or masses. In this technique, a thin, hollow needle is inserted into the mass to extract cells that, after being stained, will be examined under a microscope. The procedure serves as an alternative to usual biopsy methods that require major surgery. This work explores the use of data mining algorithms to enhance early detection of breast cancer by diagnosing breast masses from magnified images of FNAs
Willy: A Sokoban Solving Agent, June 2009
- Course: Methods for Planning and Scheduling
- Code: github
- Abstract: Sokoban is a classical, widely acclaimed, logic computer puzzle game. Despite it’s simple set of rules the complexity of its mazes is overwhelming. This paper describes Willy, our first attempt to solve Sokoban puzzles, and our study of the underlying implementation difficulties of a Sokoban search agent: the very large search space and the state transitions that create unsolvable situations. Willy uses a search algorithm, IDA* and a good heuristic, Minmatching and then uses techniques to reduce the search space: removal of unsafe positions from the map, hash tables to prevent loops, macro moves to merge together multiple states into a single state and finally relevance cuts to attempt to make only relevant moves.
A Look at Dynamic Languages, November 2007
- Course: Software Engineering
- Abstract: This paper aims to present an overview of Dynamic Languages in comparison with the more traditional languages, namely Java and C++. The definition of the term “dynamic language” is given and what is commonly understood nowadays when the term is used. Then one lists the most common features of these languages and the advantages and disadvantages pointed by their proponents and opponents. Furthermore is enumerated some of the domains in which dynamic languages have been more successful and explain the reasons that justify it, as well as the domains in which there are few or no reports of success. Finally, some common examples of fanaticism sorrounding dynamic languages are given.
Signature Recognition Using Neural Networks, May 2007
- Course: Artificial Intelligence
- Code: github
- Objective: The objective of this project is to present a solution to a simple learning task. The task chosen was signature recognition and the solution was to use an Artificial Neural Network (ANN). ANN is a computational model that tries to simulate aspects of biological neural networks. To use an ANN it is necessary first to design its structure, define how it functions and to train it to perform the task at hand, in this case, to recognize signatures.
