As linguistic models incorporate more subtle nuances of language and its structure, standard inference techniques can fall behind. Often, such models are tightly coupled such that they defy clever dynamic programming tricks. However, Sequential Monte Carlo (SMC) approaches, i.e. particle filters, are well suited to approximating such models, resolving their multi-modal nature at the cost of gen...

In an automated immunoprecipitin system for analysis of serum immunoglobulins (Technicon Instruments Corp., Tarrytown, N.Y. 10591) (1, 2) sampler lines of small inside diameter (0.0075 and 0.020 inch) must be used, and so flow is occasionally interrupted when the line becomes blocked by particulate matter. Cleaning the blocked line is simple; however, flow interruption is detected only by caref...
