  1. 11. Evolution of Artificial Brains in Simulated AnimalBehaviour

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : BJÖRN TEGELUND; JOHAN WIKSTRÖM; [2013]
    Keywords : ;

    Abstract : In this report we simulate artificial intelligence in animals using genetic algorithms. In similar models, advanced artificial neural networks have been used for decision making. We present two simpler decision-making models. READ MORE

  3. 12. Evaluation of a least-squares radial basis function approximation method for solving the Black-Scholes equation for option pricing

    University essay from Institutionen för informationsteknologi

    Author : Cong Wang; [2012]
    Keywords : RBF; radial basis function; ill-conditioning; shape parameter; Black-Scholes equation; option pricing;

    Abstract : Radial basis function (RBF) approximation, is a new extremely powerful tool that is promising for high-dimensional problems, such as those arising from pricing of basket options using the Black-Scholes partial differential equation. The main problem for RBF methods have been ill-conditioning as the RBF shape parameter becomes small, corresponding to flat RBFs. READ MORE

  4. 13. A Matlab Toolbox for fMRI Data Analysis: Detection, Estimation and Brain Connectivity

    University essay from Datorseende

    Author : Kiran Kumar Budde; [2012]
    Keywords : fMRI; functional Magnetic Resonance Imaging; Detection of activated regions; Estimation of hemodynamic response; Brain connectivity; Bayesian estimator; RBF; NARX; Granger causality.;

    Abstract : Functional Magnetic Resonance Imaging (fMRI) is one of the best techniques for neuroimaging and has revolutionized the way to understand the brain functions. It measures the changes in the blood oxygen level-dependent (BOLD) signal which is related to the neuronal activity. READ MORE

  5. 14. Adapting a Radial Basis Functions Framework for Large-Scale Computing

    University essay from Institutionen för informationsteknologi

    Author : Afshin Zafari; [2012]
    Keywords : ;

    Abstract : This work is aimed at extending a parallel computing framework for radial basis functions methods for solving partial differential equations. Existing framework uses Task Based parallelization method in shared memory architectures to run tasks concurrently on multi-core machines using POSIX Threads. READ MORE

  6. 15. When Computers Can Discuss Shape Properties with Each Other

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Xin Yu Yang; [2011]
    Keywords : shape descriptors; variational interpolation; implicit function;

    Abstract : A novel idea for perception of object surfaces is presented by so called "shape descriptors". Such idea is as an abstract level to represent the object surface by some real numbers. It has the similar idea like as the Fourier coefficients of mapping a function f(x) to frequency domain by Fourier transform. READ MORE
