    SimuMANET

    SimuMANET is a tool for deployment and real-time monitoring of MANETs

    ...The proposed tool allows analyzing the delay, traffic flows and packet losses for both the full network and single nodes. This functionality enables to determine the causes constraining the QoS accomplishment for a particular networktopology, scenario, routing algorithm, and so on. Due to a set of functionalities, such as GUI, network topology visualization, traffic and motion pattern configuration, and real-time network status analysis, the simulator here introduced becomes a valid tool for both research and education targets.

    DiffGen

    Differentially-private algorithm based on Generalization

    ...All the existing solutions that ensure epsilon-differential privacy handle the problem of disclosing relational and set-valued data in a privacy preserving manner separately. We developed an algorithm that considers both relational and set-valued data in differentially private disclosure of healthcare data.

    im2ascii

    Image to ASCII converter that takes character shape into account

    im2ascii is a small python script that converts images to ascii-art. Unlike common ascii-art generators, it does not only use each character's mean brightness, but matches the full character shape. Pro: Better ascii-art quality (see screenshots for examples) Con: Matching is very resource intensive Dependencies: Python 2.7, PIL, numpy, scipy

    Rand Tree

    Rand Tree

    Random Tree Generator for MatLab

    RandTree is a MatLab based tree simulator program where the algorithm is based on Honda's model. We have used probabilistic generation of branches in order to simulate visually realistic tree structures. This program is designed to generate branching structures with bifurcation branching pattern (sympodial branching). By changing the probabilities and branching angles, you can generate different shapes of trees.

    Averaged N-Dependence Estimators (A1DE and A2DE) achieves highly accurate classification by averaging over all of a small space of alternative naive-Bayes-like models that have weaker (and hence less detrimental) independence assumptions than naive Bayes. The resulting algorithm is computationally efficient while delivering highly accurate classification on many learning tasks. For more information, see, G. Webb, J. Boughton, Z. Wang (2005). Not So Naive Bayes: Aggregating One-Dependence Estimators. Machine Learning. 58(1):5-24 and G.I. Webb, J. Boughton, F. Zheng, K.M. Ting and H. Salem (2012). Learning by extrapolation from marginal to full-multivariate probability distributions: decreasingly naive {Bayesian} classification. ...

    Connect Four

    A simple connect four game in C#

    This is a small and simple project which i used to work on creating a minimax algorithm. In its current state, the algorithm is finished. Future updates will try to: 1. Add heuristics instead of just checking for wins 2. Introduce alpha-beta pruning Other updates not concerning the AI will be: 1. Coins will fall down into place, instead of appearing 2. You can set if you want to play with 2 humans, 2 computers or an AI and a human. 3.
