Finding Good Termination Probability for Random-walks
In this paper we study the survival probability of the followed ray in random walk global illumination algorithms. When the ray hits a surface, the survival probability is responsible for the dying of the ray, thus for finishing the walk. We examine the variance of the Russian roulette random walk estimator of gathering type, give an explanation of the formula and show visually the behavior of ...
متن کاملForced Spectrum Access Termination Probability Analysis under Restricted Channel Handoff
Most existing works on cognitive radio networks assume that cognitive (or secondary) users are capable of switching/jumping to any available channel, regardless of the frequency gap between the target and the current channels. Due to hardware limitations, cognitive users can actually jump only so far from where the operating frequency of their current channel is, given an acceptable switching d...
متن کاملProbability Value Library 1
Hidden Markov models (HMMs) and other time series models assign probabilities to long sequences of events. Avoiding underrow is arguably the central diiculty in calculating the probability of such sequences. This technical report presents an elegant and eecient C library for representing and manipulating probability values without underrow. Use of the library results in simpler code whose execu...
متن کاملLecture 1: Algorithmic Probability
The Subject of this Series of Lectures is: Strong A.I. — what it is, how we may achieve it — apparent obstacles to achieving it — and how to overcome these obstacles. First: What is “strong A.I.”? My own personal interest is in a machine that is at least as good as a human in solving problems in Math, Science, and most aspects of Engineering. Eventually, through its ability to improve itself, a...
