Abstract
This talk will provide a tutorial style introduction to sequential Monte Carlo methods, attempting to start from a basic introduction, to a coverage of some of the latest research developments.
Sequential Monte Carlo methods are applied in a wide variety of applications, including engineering, economics and biology. They combine importance sampling and resampling to approximate distributions. The idea is to introduce a sequence of proposal densities and sequentially simulate a collection of N >1 samples, termed particles, in parallel from these proposals. In most scenarios it is not possible to use the distribution of interest as a proposal. Therefore, one must correct for the discrepancy between proposal and target via importance weights. There are a variety of algorithms and extensions which form some of the most cutting edge methodology for `exact' computations in many academic fields.
