Investigation of connection between deep learning and probabilistic graphical models
… of boosting weak rules into an ensemble is weighted sampling. Finally regularizing neural networks using the dropout technique is conditioning on certain observations in PGMs.

PSF Sampling in Fluorescence Image Deconvolution
… for an optimal result. Additionally, we do a weighted sampling of the point spread function to avoid unnecessary computations and prioritize non-zero signals. In a baseline comparison against the Richardson-Lucy method, our algorithm outperforms RL for images affected with high levels of …

The rate of profit as a random variable
… values, are used in conjunction with a size-weighted sampling scheme to identify possible models for distributions of the profit rate at the capital level. <br></br><br></br>Farjoun and Machover derive their hypothesis from a particular conception of the process of capitalist competition. A …

Probabilistic characterization and synthesis of complex driven systems
… the performance of an instrument. Cluster-weighted modeling (CWM), a mixture density estimator around local models, is presented as a framework for function approximation and for the prediction and characterization of nonlinear time series. The general model architecture and estimation …

Weighted Generalization of Rayleigh and Related Class of Distributions
<p>Weighted distributions occur naturally and frequently in research related to reliability, bio-medicine, ecology and in the modeling of clustered sample, heterogeneity, and extraneous variation. In the analysis of intervention data, the expected value of the duration to completion of a random …

Pedestrian Safety in Peru: The role of visible signalization, transit stops and other features of the built environment
… there were 97 incidents at intersections (weighted N=1134) and 40 at mid-blocks (weighted N=469) that met study criteria. Each case was matched to one control based on proximity, street classification and number of lanes. Site characteristics were recorded February, 2011 to September, 2011. …

Movement of fishes in a network of streams and implications for persistence
… over distance and generate biased or distance-weighted movement data, where short distances are sampled more frequently than long distances. I examined how study design affects the degree of distance-weighted sampling and observed movement distributions of stream fish. A modeling study …

Network Anomaly Detection with Incomplete Audit Data
… phase, we have implemented an adaptive sampling scheme that intelligently samples incoming network data to reduce the volume of traffic sampled, while maintaining the intrinsic characteristics of the network traffic. A Bloom filters based fast flow aggregation scheme is employed at the …

Assessing the Nonpoint Source Pollutant Removal Efficiencies of a Two-Basin Stormwater Management System in an Urbanizing Watershed
… sites for flow measurement, water quality sampling, and biotic assessments (habitat evaluation and rapid bioassessment of benthic macroinvertebrates) were located above and below each of the ponds. Both grab samples and automated samples were collected at these stations. Between 1997 and …
