In reinforcement learning (RL), the ability to utilize prior knowledge from previously solved tasks can allow agents quickly solve new problems. some cases, these problems may be approximately by composing solutions of primitive (task composition). Otherwise, used adjust reward function for a problem, in way that leaves optimal policy unchanged but enables quicker (reward shaping). this work, w...

A wavelet-based coder-decoder (codec) structure is deened for baseband waveform coding. Numerical results for bandwidth eeciency are given, and a comparison between several diier-ent wavelets is presented. Moreover, it is shown that wavelets obey the Nyquist pulse shaping condition and provide a uniied framework for analog pulse shaping concepts of communications.

Synonyms for “traffic shaping” include “packet shaping,”“bandwidth limiting,”“rate limiting,...

The aim of this study is to propose simple and reliable techniques to assess the condition of metal oxide arrester based on the dielectric response techniques. A number of modern electrical diagnostics for Metal Oxide Surge Arrester (MOSA) are discussed in this paper. The techniques included return voltage, decay voltage and polarisation/depolarisation current measurement. The single and multip...

Is there life after video coding standards? One might think that research has no room to advance with the video coding standards already defined. On the contrary, exciting research opportunities arise after the standards are specified. In this paper, we introduce two standard-related research areas: rate shaping and error concealment, as examples of interesting research that finds its context i...

This study examines the roles of gesture repetition in the process of collaboratively shaping ideas. The data involve three college students brainstorming for the production of a short film. Employing primarily language and depictive gestures, the participants collaboratively shape ideas of the film scenes, characters’ actions, and camerawork; they accept or reject each other’s proposals, elabo...

A control profile is generated which suppresses one or more resonant dynamics in a flexible dynamic system. This control profile can be used as a velocity profile, or as a shape filter to an arbitrary control command. The robustness can be arbitrarily improved, which brings about a smoother profile. The technique can be applied to both open-loop and closed-loop systems.

We examine the properties of a promising new traac descriptor for ATM networks, namely the entropy of cell streams. The entropy is a measure of the disorganization among cells within a traac stream; alternatively we can say that entropy captures the amount of randomness in cell scattering. We study the entropy of ON-OFF sources with respect to the typical queue parameters of interest: average q...
