using game theory techniques in self-organizing maps training
شبکه خود سازمانده پرکاربردترین شبکه عصبی برای انجام خوشه بندی و کوانتیزه نمودن برداری است. از زمان معرفی این شبکه تاکنون، از این روش در مسائل مختلف در حوزه های گوناگون استفاده و توسعه ها و بهبودهای متعددی برای آن ارائه شده است. شبکه خودسازمانده از تعدادی سلول برای تخمین تابع توزیع الگوهای ورودی در فضای چندبعدی استفاده می کند. احتمال وجود سلول مرده مشکلی اساسی در الگوریتم شبکه خودسازمانده به حسا...
Discovering Novel Digital Circuits using Evolutionary Techniques
Modern FPGAs provide a platform for implementation of uncommitted logic arrays which are also, in many cases, reconfigurable. Whilst this allows circuit functionality to be changed in time, it also provides a convenient environment in which to encourage the direct evolution (using genetic algorithms) of those circuit solutions themselves. In this paper we describe experiments which examine the ...
متن کاملUnderwater voice communications using digital techniques
A digital signal processor (DSP) based voice communication system for divers with a 2400 bitls transmission rate is described. Each speech signal frame is analysed using linear predictive coding (LPC) and the essential parameters such as amplitude, pitch period and digital filter coefficients are extracted. These parameters are transmitted through a water channel at a rate of 2400 bitls by empl...
متن کاملAC resistance measurements using digital sampling techniques
Here we will present measurement results for ac resistors calibrations, made with a four terminal-pair digital impedance bridge, developed at Inmetro. This bridge operates in a wide frequency and value ranges, for both in-phase and quadrature measurements, with uncertainties bearing some μΩ/Ω.
متن کاملEfficacy of Digital Anesthesia: Comparison of Two Techniques
BACKGROUND Digital nerve block is commonly performed by care providers in medical fields. This study compares the blocks in terms of effectiveness of anesthesia and pain. METHODS Patients were divided into two groups. First group underwent digital block whereas 2nd group had transmetacarpal digital block. The subcutaneous ring block was performed by two injections of 3 ml of 2% lignoca...
