[ 1 ] - استخراج ویژگی‌ها جهت بازشناسی اشیا با الهام از بینایی انسان
در این مقاله سعی شده است تا با الگو برداری از سامانه‌ی بینایی انسان، یک روش مقاوم و تکرارپذیر برای بازشناسی اشیا ارائه شود. یکی از معروفترین مدلهای ارائه شده مبتنی بر بینایی انسان، مدل HMAX میباشد که عمل‌کرد مناسبی در بازشناسی اشیا از خود نشان داده است. اما تفاوتهایی نیز بین این مدل و بینایی انسان وجود دارد، به طوری که رویه‌ی مغز به طور کامل مدل نشده است. از جمله نواقص این مدل میتوان به تک...
[ 2 ] - Novel Radial Basis Function Neural Networks based on Probabilistic Evolutionary and Gaussian Mixture Model for Satellites Optimum Selection
In this study, two novel learning algorithms have been applied on Radial Basis Function Neural Network (RBFNN) to approximate the functions with high non-linear order. The Probabilistic Evolutionary (PE) and Gaussian Mixture Model (GMM) techniques are proposed to significantly minimize the error functions. The main idea is concerning the various strategies to optimize the procedure of Gradient ...
[ 3 ] - Accurate Determination of GPS Receiver with Different Classification Methods
One of the instruments for determination of position used in several applications is the Global Positioning System (GPS). With a cheap GPS receiver, we can easily find the approximate position of an object. Accuracy estimation depends on some parameters such as dilution of precision, atmospheric error, receiver noise, and multipath. In this study, position accuracy with GPS receiver is classifi...
[ 4 ] - On Feasibility of Adaptive Level Hardware Evolution for Emergent Fault Tolerant Communication
A permanent physical fault in communication lines usually leads to a failure. The feasibility of evolution of a self organized communication is studied in this paper to defeat this problem. In this case a communication protocol may emerge between blocks and also can adapt itself to environmental changes like physical faults and defects. In spite of faults, blocks may continue to function since ...
