Cut-off Sampling Design: Take all, Take Some, and Take None

Extended Abstract. Sampling is the process of selecting units (e.g., people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen. To draw a sample from the underlying population, a variety of sampling methods can be employed, individually or in combination. Cut-off sampling is a pr...

Multi-step Off-policy Learning Without Importance Sampling Ratios

To estimate the value functions of policies from exploratory data, most model-free offpolicy algorithms rely on importance sampling, where the use of importance sampling ratios often leads to estimates with severe variance. It is thus desirable to learn off-policy without using the ratios. However, such an algorithm does not exist for multi-step learning with function approximation. In this pap...

STUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS

Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...

Postmortem sampling of the pancreas for histological examination: what is the optimum cut-off time?

The pancreas is a solid organ rich in digestive enzymes. Hence, autolytic changes set in early after biological death. Tomita et al., analyzing postmortem samples from different organs at intervals of 1, 3, 5, 10, 15 and 24 hours, found that the pancreas showed the earliest changes at 1 hour after death [1]. The optimum time before which tissue samples should be obtained from the pancreas for p...
