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...
Fault Diagnosis in Rotating Mechanical Systems Using Self-organizing Maps
The power of Self-Organizing Maps (SOM) for the visualization of highdimensional data has been well recognized over the past decade. They map nonlinear statistical relationships among different variables of a high dimensional input data on a low dimensional network, preserving most of the topographic relationships from the input space. This paper presents an SOMbased multi-sensor diagnostic sys...
متن کاملFault Prediction in Aircraft Engines Using Self-Organizing Maps
Aircraft engines are designed to be used during several tens of years. Their maintenance is a challenging and costly task, for obvious security reasons. The goal is to ensure a proper operation of the engines, in all conditions, with a zero probability of failure, while taking into account aging. The fact that the same engine is sometimes used on several aircrafts has to be taken into account t...
متن کاملHeterogeneity-aware Fault Tolerance using a Self-Organizing Runtime System
Due to the diversity and implicit redundancy in terms of processing units and compute kernels, off-the-shelf heterogeneous systems offer the opportunity to detect and tolerate faults during task execution in hardware as well as in software. To automatically leverage this diversity, we introduce an extension of an online-learning runtime system that combines the benefits of the existing performa...
متن کاملSelf-Organizing Visual Maps
This paper deals with automatically learning the spatial distribution of a set of measurements: images, in the examples presented here. The solution to this problem can be viewed as an instance of robot mapping although it can also be used in other contexts. We examine the problem of organizing an ensemble of images of an environment in terms of the positions from which the images were obtained...
