چکیده مقاله :
امروزه، سیستمهاي طبقهبندي کننده یادگیر درکاربردهاي متنوع در رباتیک مانند رباتهاي حسي، رباتهاي انساننما، سامانه هاي امداد و جات هوشمند وکنترل ربانهاي فیزیکي در محیطهاي گسسته و پیوسته، مورد توجه قرار گرفته است. معمولا از ترکیب یک الگوریتم تکاملي یا روشهاي شهودي با یک فرایند یادگیري براي جستجو در فضاي قوانین موجود در انتساب کنش مناسب یک دستهبند استفاده مي شود. چالش مهم براي بالا بردن سرعت و دقت در رسیدن به هدف در مسائل هزار تو، بکارگیري و انتخاب کنشي است که محرک بجاي برخورد تکراري به موانع اطراف، در مسیر درست قرار گیرد. بدین منظور در این مقاله یک الگوریتم طبقه بندي کننده یادگیر هوشمند سیستمهاي طبقه بند یادگیر مبتني بر دقت) XCS ( مبتني بر حافظه محدود بکار گرفته شده است که با توجه به ورودي و کنشهاي اعمال شده به محیط و عکس العمل محرک، قوانین بهینه شناسایي شده و در اولویت انتخاب با احتمال بیشتري در مراحل بعدي، به عنوان مجموعه دستهبند جدید به الگوریتم سیستمهاي طبقه بند یادگیر مبتني بر دقت (XCS) اضافه گردد. از جمله دستاوردهاي این روش مي توان به کاهش تعداد مراحل لازم و افزایش سرعت در رسیدن محرک به هدف در مقایسه با الگوریتم سیستمهاي طبقه بند یادگیر مبتني بر دقت (XCS) پایه داشت .
Nowadays, learning classifier systems have received attention in various applications in robotics, such as sensory robots, humanoid robots, intelligent rescue and rescue systems, and control of physical robots in discrete and continuous environments. Usually, the combination of an evolutionary algorithm or intuitive methods with a learning process is used to search the space of existing rules in assigning the appropriate action of a category. The important challenge to increase the speed and accuracy in reaching the goal in the maze problems is to use and choose the action that the stimulus is placed on the right path instead of repeatedly hitting the surrounding obstacles. For this purpose, in this article, an intelligent learning classifier algorithm of accuracy-based learning classifier systems (XCS) based on limited memory is used, which according to the input and actions applied to the environment and the reaction of the stimulus, the rules It is optimally identified and added as a new classifier set to the accuracy-based learning classifier systems (XCS) algorithm in the next steps. Among the achievements of this method, it can be based on reducing the number of necessary steps and increasing the speed of reaching the stimulus to the target compared to the accuracy-based learning classifier systems (XCS) algorithm.
