To quickly adjust the controller settings in real-time, it becomes necessary to use intelligent control algorithms. In this paper, we propose an approach to tuning the speed controller of a vibration machine, which will ensure its maximum performance, using the reinforcement learning method. In this context of problem solving, the policy is presented in a parametric family of controller gains. In this case, the agent interacts with the virtual environment and the PI controller is implemented the software. The effectiveness of the proposed approach has been verified by real-time simulation and experiments on the two-rotor vibration unit. The advantage of the described learning algorithm is that the complex system is considered a black box. Thus, it is required to know the reference drive speed and measure the output speed.","PeriodicalId":110836,"journal":{"name":"2022 6th Scientific School Dynamics of Complex Networks and their Applications (DCNA)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125145167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main feature of this concept is the rejection of analog-to-digital and digital-to-analog conversions when capturing input visual data for a spiking neural network (SNN) based on memristive devices. This can be achieved by combining photodiodes and memristors and directly feeding analog pulses from the output of such a circuit to the input of a SNN circuit. This concept relates to the field of in-memory and in-sensor computing and will makes it possible to create more compact, energy-efficient visual processing units for wearable, on-board and embedded electronics for such areas as robotics, the Internet of Things, neuroprosthetics and other practical applications in the field of artificial intelligence.","PeriodicalId":110836,"journal":{"name":"2022 6th Scientific School Dynamics of Complex Networks and their Applications (DCNA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125661064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agent interactions are aimed at enhancing speed, quality, and complexity characterictics, nevetheless, each interaction may worse single agent results as well as enhance them. Therefore, building effective communication patterns is of high interest for learning process of intelligent systems. As an applied task, we consider project execution dynamics, where single tasks are assigned to employees having several conflicting parameters, while an intelligent system consists of multiple intelligent agents, learned by reinforcement algorithms. Different patterns of interaction according to agent similarities are explored as a factor affecting learning process. The condition of two agents connection is there similarity value, greater than some determined threshold; similarity function is determined for five static and dynamics parameters, and their influence is regulated by the corresponding five multipliers. The experiment shows there are significant parameters, showing more effect of connection on learning dynamics. This can be seen via effect of parameters, regulating neighbours contribution.","PeriodicalId":110836,"journal":{"name":"2022 6th Scientific School Dynamics of Complex Networks and their Applications (DCNA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122374581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, it was shown that such a system is capable of demonstrating long transients simulating epileptiform activity similarly to the previously considered models.
