Listing of Communication in Scripts

The submission considers a case where you deduce what weather it is given the status of a shirt that is hung outside. The weather could be Sunny, cloudy, Rainy and the shirt could be dry, dryish, damp etc. Now given some probability matrices (The initial probability of the weather, the transition probability of the weather and the observation given weather matrices), can the chain of weather be deduced? The Viterbi algorithm is used to decode the states.

  • Platform: Matlab, Scripts

This software has been realized at the Technology Lab, Department of Cognitive and Neural Systems, Boston University - http://techlab.bu.edu. The main author of the software is Praveen Pilly ( http://techlab.bu.edu/members/advait/ ). How does the brain make perceptual decisions? Speed and accuracy of saccadic decisions regarding motion direction depend on the inherent ambiguity in the motion stimulus and correlate with the temporal dynamics of firing rates in parietal and frontal cortical neurons of macaque monkeys.

Occasionally I see a request for computation of a running, windowed standard deviation. This is easily accomplished using filter and the alternative formula for the standard deviation: std = sqrt((sum(x.^2) - n*xbar.^2)/(n-1)). Movingstd allows you to specify forward, backward or central windows of any desired length.

The gradient function in Matlab allows you to compute the slope of a curve along its entire length. But if your curve is a noisy one, then gradient will also be noisy. In this event one might desire to fit a moderately low order polynomial regression model in a sliding window, then differentiate that model.

This application can be useful to understand how to use microphone (and timer) and how to record. Just execute the file, then click "test" and say a word (wait 1 second) say another word, etc. you can save and load the database. I used this software for voice recognition but I only left the recorder part in this file.

A given polynomial p(x) is transformed into a rational function r(x). The poles and residues of the derived rational function are found to be equivalent to the roots and multiplicities of the original polynomial. p(x) = Given polynomial = PROD[k=1:K]{(x - z_k)^m_k} d(x) = (d/dx)p(x) g(x) = GCD(p(x),d(x)) u(x) = p(x)/g(x) w(x) = (d/dx)u(x) v(x) = d(x)/g(x) r(x) = v(x)/u(x) = SUM[k=1:K]{m_k/(x - z_k)} Thus, the roots z_k are computed from solving the simple-root polynomial u(x)=0, instead of the original multiple-root polynomial p(x)=0; and the multiplicities m_k are determined as the partial fraction expansion coefficients of the derived rational function r(x)=v(x)/u(x), z_k = Roots(u(x)), k=1,K m_k = v(z_k)/w(z_k), k=1,K In addition, re-constructing a polynomial pz(x) from the computed z_k and m_k, the overall deviation error of the original polynomial p(x) is calculated, er = Norm(pz - p)/Norm(p) The polynomial GCD is calculated from "Monic polynomial subtraction" derived from the longhand polynomial division in classical Euclidean GCD algorithm.

Given a neural network object, this function returns the closed, symbolic, expression implemented by the network (as a string). This allows you to use a neural network model without relying on the neural network toolbox. Note I only implemented for feed forward nets (MLPs) and not all possible transfer functions are supported.
