Critical Points When There Is No Saddle Point Geometry
We show how mountain pass methods can be used even when there is no mountain pass or saddle point geometry. The functional can grow on linking subsets. Applications are given.

Abstract If a prior probability does not exist or is controversial, can we formulate probabilistic inference based only on the properties of the measurement? In the case of plain ‘location’ measurements the answer to this is known. Here we extend that answer to address the general problem of estimating a scalar parameter from a small data sample. That measurement is treated as if resulting from...

متن کاملJust say no: how are visual searches terminated when there is no target present?
How should a visual search task be terminated when no target is found? Such searches could end after a serial search through all items, but blank trials in many tasks are terminated too quickly for that to be plausible. This paper proposes a solution based on Wolfe's (1994) Guided Search model. The probability that each item is a target is computed in parallel based on items' differences from e...
