Policy optimization in reinforcement learning requires the selection of numerous hyperparameters across different environments. Fixing them incorrectly may negatively impact performance leading notably to insufficient or redundant learning. Insufficient (due convergence local optima) results under-performing policies whilst wastes time and resources. The effects are further exacerbated when usi...

In many cases, redundant systems are beset by both independent and dependent failures. Ignoring dependent variables in MTBF evaluation of redundant systems hastens the occurrence of failure, causing it to take place before the expected time, hence decreasing safety and creating irreversible damages. Common cause failure (CCF) and cascading failure are two varieties of dependent failures, both l...

In the field of image processing and computer vision (CV), machine learning (ML) architectures are widely used. Image compression problems can be solved using convolutional neural networks (CNNs). As a result bandwidth memory constraints, images is necessity. There three types information found in images: useful, redundant, irrelevant. this survey, we will discuss how ML used to compress lossy ...

PURPOSE To examine the association of personal values, the built environment, and auto availability with walking for transportation. SETTING Participants were drawn from 11 U.S. metropolitan areas with good transit services. SUBJECTS 865 adults who had recently made or were contemplating making a residential move. MEASURES Respondents reported if walking was their primary mode for nine tr...

Land-sea contamination observed in SMOS (Soil Moisture and Ocean Salinity) brightness temperature images is found to have two main contributions: the floor error inherent of image reconstruction and a multiplicative error either in the antenna temperature or in the visibility samples measured by the correlator. The origin of this last one is traced down to SMOS calibration parameters to yield a...

Creating computer graphics based content for stereoscopic and auto-stereoscopic displays requires to render a scene several times from slightly different viewpoints. In that case, maintaining real-time rendering can be a difficult goal if the geometry reaches thousands of triangles. However, similarities exist among the vertices belonging to the different views like the texture, some transforma...
