WebbSampling may be defined as the selection of some part of an aggregate or totality on the basis of which a judgment or inference about the population (aggregate or totality) is made. In other words, it is the process of obtaining information about an entire population by examining only a part of it. 6. Need for sampling 1. WebbThe sampling theorem states that, “a signal can be exactly reproduced if it is sampled at the rate f s, which is greater than or equal to twice the maximum frequency of the given signal W .”. Mathematically, we can write it as. f s ≥ 2 W. Where, f s is the sampling rate. W is the highest frequency of the given signal. inches to sq metresWebb30 okt. 2014 · Sampling Theory Determining the distribution of Sample statistics.

WebbA Bayesian model of learning to learn by sampling from multiple tasks is presented. The multiple tasks are themselves generated by sampling from a distribution over an environment of related tasks. Such an environment is shown to be naturally modelled within a Bayesian context by the concept of an objective prior distribution.
