q learning for scheduling

Action a must be chosen which maximizes, Q(s,a). better optimal scheduling solutions when compared with other adaptive and non-adaptive Distributed computing is a viable and cost-effective alternative to the traditional model of computing. The experiment results demonstrate the efficiency of our proposed approach compared with existing … This validates the hypothesis that the proposed approach provides View of Q-Learning Scheduler and Load Balancer. Q-Learning is a model-free form of machine learning, in the sense that the AI "agent" does not need to know or have a model of the environment that it will be in. Before scheduling the tasks, the QL Scheduler and Load balancer dynamically gets a list of available resources from the global directory entity. to the problem of scheduling and Load Balancing in the grid like environment Majercik and Littman (1997) evaluated, how the load balancing problem can be formulated as a Markov Decision Process (MDP) and described some preliminary attempts to solve this MDP using guided on-line Q-learning and a linear value function approximator tested over small range of value runs. Reinforcement learning signals: The scheduling problem is known to be NP-complete. (1998) proposed five Reinforcement Based Schedulers (RBSs) which were: 1) Random RBS 2) Queue Balancing RBS 3) Queue Minimizing RBS 4) Load Based RBS 5) Throughput based RBS. The trial and error learning feature and the concept of reward makes the reinforcement learning distinct from other learning techniques. current input and gets its action set A, Reward Calculator calculates reward by considering five vectors as reward Redistribution of tasks from heavily In the past, Q‐learning based task scheduling scheme which only focuses on the node angle led to poor performance of the whole network. Distributed systems are normally heterogeneous; provide attractive scalability in terms of computation power and memory size. However, Tp does not significantly change as processors are further increased In consequence, scheduling issues arise. number of processors, Cost There are some other challenges and Issues which An initially intuitive idea of creating values upon which to base actions is to create a table which sums up the rewards of taking action a in state s over multiple game plays. platform is still a hindrance. can be calculated by Eq. First, the Q‐learning framework, including state set, action set, and rewards function is defined in a global view so as to forms the basis of the QFTS‐GV scheme. Finally, the Log Generator generates log of successfully executed tasks. based on actions taken and reward received (Kaelbling et al., 1996) (Sutton This allows the system The factors of performance degradation during parallel execution are: the frequent communication among processes; the overhead incurred during communication; the synchronizations during computations; the infeasible scheduling decisions and the load imbalance among processors (Dhandayuthapani et al., 2005). Q-learning is a type of reinforcement learning that can establish a dynamic scheduling policy according to the state of each queue without any prior knowledge on the network status. Galstyan et al. Execution Energy consumption of task scheduling is associated with a reward of nodes in the learning process. The experimental results show that the scheduling strategy is better than the scheduling strategy based on the standard policy gradient algorithm, and accelerate the convergence speed. In addition to being readily scalable, DEEPCAS is completely model-free. In deep Q-learning, we use a neural network to approximate the Q-value function. ... We will now demonstrate how to use reinforcement learning to schedule UAV cluster tasks. time for 8000 episodes vs. 4000 episodes with 30 input task and increasing performance. By using Q-Learning, the multipath TCP node in the vehicular heterogeneous network can continuously learn interactively with the surrounding environment, and dynamically adjust the number of paths used for … 1. Again this graph shows the better performance of QL scheduler with other scheduling techniques. Based on developments in WorkflowSim, experiments are conducted that comparatively consider the variance of makespan and load balance in task scheduling. The multidimensional computational matrices and povray is used as a benchmark to observe the optimized performance of our system. of tasks for 500 Episodes and 8 processors. Q-Values or Action-Values: Q-values are defined for states and actions. Equation 9 defines, how many numbers of subtasks will be given to each resource. They employed the Q-III algorithm to Guided Self Scheduling (GSS) (Polychronopoulos and Kuck, 1987) and factoring (FAC) (Hummel et al., 1993) are examples of non-adaptive scheduling algorithms. The random scheduler and the queue-balancing RBS proved to be capable of providing good results in all situations. on grid resources. The algorithm considers the packet priority in combination with the total number of hops and the initial deadline. The information exchange medium among the sites is a communication network. The experiments were conducted on a Linux operating system kernel patched with OpenMosix as a fundamental base for resource collector. This algorithm was receiver initiated and works locally on the slaves. to learn better from more experiences. The problem with Q-earning however is, once the number of states in the environment are very high, it becomes difficult to implement them with Q table as the size would become very, very large. β is a constant for determining number of sub jobs calculated by averaging outside the boundary will be buffered by the Task Collector. The optimality and scalability of QL-Scheduling was analyzed by testing it against adaptive and non-adaptive Scheduling for a varying number of tasks and processors. Problem description: The aim of this research is to solve scheduling These algorithms are broadly classified as non-adaptive and adaptive algorithms. and Fig. time and size of input task and forwards this information to State Action Q-learning is a very popular and widely used off-policy TD control algorithm. 3. In ordinary Q-learning, Q-table is used to store the Q value of each state–action pair when the state and action spaces are discrete and the dimension is not high. The system consists of a large number of heterogeneous reinforcement learning agents. Reinforcement learning: Reinforcement Learning (RL) is an active area of research in AI because of its widespread applicability in both accessible and inaccessible environments. The second level of experiments describes the load and resource effect on Q-Scheduling and Other Scheduling (Adaptive and Non-Adaptive). From the learning point of view, performance analysis was conducted for a large number of task sizes, processors and episodes for Q-Learning. At its heart lies the Deep Q-Network (DQN), a modern variant of Q learning, introduced in [13]. parameters using, Detailed not need model of its environment. There was no information exchange between the agents in exploration phase. Q learning is a value based method of supplying information to inform which action an agent should take. 10 depict an experiment in which a job, composed of 100 tasks, runs multiple times on a heterogeneous cluster of four nodes, using Q-learning, SARSA and HEFT as scheduling algorithms. For a given environment, everything is broken down into "states" and "actions." knowledge of all the jobs in a heterogeneous environment. As shown in Fig. Prerequisites: Q-Learning technique. 2. We then extend our system model to a more intelligent microgrid system by adopting multi-agent learning structure where each customer can decide its energy consumption scheduling based on the observed retail price aiming at min- This could keep track of which moves are the most advantageous. ©äžž‡;Ã① ’Œ‚@ a2)²±‰‹KZZÂÓÌÆÆ `£ ’D)܈¼‹” 6BÅÅ.îÑ(‘ç€b. Q-Learning was selected due to the simplicity of its formulation, the ease with which parameters given below: Repeat for each step of episode (Learning), Take action a, observe reward r, move next state s', QL History Generator stores state action pairs (s, Task Mapping Engine, Co-allocation is done by the Task Mapping Engine; https://scialert.net/abstract/?doi=jas.2007.1504.1510. Q-learning gradually reinforces those actions Thus, a Q‐learning based flexible task scheduling with global view (QFTS‐GV) scheme is proposed to improve task scheduling success rate, reduce delay, and extend lifetime for the IoT. Q-learning is one of the easiest Reinforcement Learning algorithms. Large degrees of heterogeneity add additional complexity to the scheduling problem. A distributed system is made up of a set of sites cooperating with each other for resource sharing. Both simulation and real-life experiments are conducted to verify the … Pair Selector. Parent et al. I guess I introduced some very different terminologies here. The essential idea of our approach uses the popular deep Q -learning (DQL) method in task scheduling, where fundamental model learning is primarily inspired by DQL. (2005) proposed algorithm. In short we can say that, Load balancing and Scheduling are crucial factors for grid like distributed heterogeneous systems (Radulescu and van Gemund, 2000). status information at the global scale. This paper discusses how Reinforcement learning in general and Q-learning in particular can be applied to dynamic load balancing and scheduling in distributed heterogeneous system. When in each state the best-rewarded action is chosen according to the stored Q-values, this is known as greedy-method. quick information collection at run-time in order to use it for rectification Sub-module description of QL scheduler and load balancer: Where Tw is the task wait time and Tx is the task execution time. As each agent would learn from the environment’s response, taking into consideration five vectors for reward calculation, the QL-Load Balancer can provide enhanced adaptive performance. For this reason, scheduling is usually handled by heuristic methods which provide reasonable solutions for restricted instances of the problem (Yeckle and Rivera, 2003). that contribute to positive rewards by increasing the associated Q-values. Action a must be chosen which maximizes, Q(s,a). This threshold value indicates overloading and under utilization of resources. ment of a deep reinforcement learning-based control-aware scheduling algorithm, DEEPCAS. Thus, a Q‐learning based flexible task scheduling with global view (QFTS‐GV) scheme is proposed to improve task scheduling success rate, reduce delay, and extend lifetime for the IoT. The goal of this study is to apply Multi-Agent Reinforcement Learning technique Dynamic load balancing is NP complete. The Application of Reinforcement Learning to Optimal Scheduling of Maintenance proposed [37] including Q-Learning [38]. γ value is zero Probably because it was the easiest for me to understand and code, but also because it seemed to make sense. is decreasing when the number of episodes increasing. To improve the performance of such grid like systems, the scheduling and load balancing must be designed in a way to keep processors busy by efficiently distributing the workload, usually in terms of response time, resource availability and maximum throughput of application. of processors for 5000 Episodes, Cost The model of the reinforcement learning problem is based on the theory of Markov Decision Processes (MDP) (Stone and Veloso, 1997). The essential idea of our approach uses the popular deep Q-learning (DQL) method in task scheduling, where fundamental model learning is primarily inspired by DQL. and Barto, 1998). number of processors, Execution The results from Fig. There was less emphasize on exploration phase and heterogeneity was not considered. It works by maintaining an estimate of the Q-function and adjusting Q-values QL Analyzer receives the list of executable tasks from Task Manager and (2004) improved the application as a framework of multi-agent reinforcement learning for solving communication overhead. This threshold value will be calculated from its historical performance on the basis of average load. Abstract: Energy saving is a critical and challenging issue for real-time systems in embedded devices because of their limited energy supply. and dynamically distribute the workload over all available resources in order Peter, S. 2003. algorithms. The architecture diagram of our proposed system is shown in Fig. 1. (2002) implemented a reinforcement learner for distributed load balancing of data intensive applications in heterogeneous environment. Employs a Reinforcement Learning algorithm to find an optimal scheduling policy The second section consists of the reinforcement learning model, which outputs a scheduling policy for a given job set. We will try to merge our methodology with Verbeeck et al. The comparison between Q-learning & deep Q-learning is wonderfully illustrated below: Ò$d«”ˆ,:cb"èÙz-ÔT±ñú"„,A‰¥S}á techniques such as AF and AWF. The key features of our proposed solution are: Support for a wide range of parallel applications; use of advance Q-Learning techniques on architectural design and development; multiple reward calculation; and QL-analysis, learning and prediction*. 8, we consider that a cluster … Scheduling with Reinforcement Learning ... we adopt the Q-learning algorithm with proposing two im-provements: alternative state definition and virtual experience. It can loaded processors to lightly loaded ones in dynamic load balancing needs On finding load imbalance, Performance Monitor signals QL Load Balancer to start its working and remapping the subtasks on under utilized resources. of scheduling technique. Dynamic load balancing assumes no prior knowledge of the tasks at compile-time. comparison of QL Scheduling vs. Other Scheduling with increasing number The limited energy resources of WSN nodes have determined researchers to focus their attention at energy efficient algorithms which address issues of optimum communication, … Algorithm is The states are observations and samplings that we pull from the environment, and the actions are the … number of episodes and processors. We can see from tables that execution time Zomaya et al. Based on developments in WorkflowSim, experiments are conducted that comparatively consider the variance of makespan and load balance in task scheduling. The State Action Pair Selector searches the nearest matched states of The main contribution of this paper is to develop a deep reinforcement learning-based \emph{control-aware} scheduling (\textsc{DeepCAS}) algorithm to tackle these issues. Figure 8 shows the cost comparison with increasing number of tasks for 8 processors and 500 episodes. where ‘a’ represent the actions and ‘s’ represent the states and ‘Q(s, a)’ is the Q value function of the state-action pair ‘(s, a)’.. Value-iteration methods are often carried out off-policy, meaning that the policy used to generate behavior for training data can be unrelated to the policy being evaluated and improved, called the estimation policy [11, 12].Popular value-iteration methods used in dynamic … for each node and update these Q-Values in Q-Table. To tackle … a, b, c, After receiving RL signal Reward Calculator calculates reward and update Q-value in Q-Table. Adaptive Factoring (AF) (Banicescu and Liu, 2000) dynamically estimated the mean and standard deviation of the iterate execution times during runtime. In Q-Learning, the states and the possible actions in a given state are discrete and finite in number. The aspiration of this research was fundamentally a challenge to machine learning. The queue balancing RBS had the advantage of being able to schedule for a longer period before any queue overflow took place. Q-Table Generator generates Q-Table and Reward-Table and places reward and epsilon greedy policy is used in our proposed approach. Distributed heterogeneous systems emerged as a viable alternative to dedicated parallel computing (Keane, 2004). Q-learning: The Q-learning is a recent form of Reinforcement Learning. time for 5000 episodes vs. 200 episodes with 60 input task and increasing non-adaptive techniques such as GSS and FAC and even against the advanced adaptive show the cost comparison for 500, 5000 and 10000 episodes respectively. [18] extended this algorithm by using a reward function based on EMLT (Estimated Mean LaTeness) scheduling criteria, which are effective though not efficient. Reinforcement Learning is a type of Machine Learning paradigms in which a learning algorithm is trained not on preset data but rather based on a feedback system. Performance Monitor is responsible for backup of system failure and signals for load imbalance. The same algorithm can be used across a variety of environments. To solve these core issues like learning, planning and decision making Reinforcement Learning (RL) is the best approach and active area of AI. It has been shown by the communities of Multi-Agents Systems (MAS) and distributed Artificial Intelligence (AI) that groups of autonomous learning agents can successfully solve the issues regarding different load balancing and resource allocation problems (Weiss and Schen, 1996; Stone and Veloso, 1997; Weiss, 1998; Kaya and Arslan, 2001). Resource Analyzer displays the load statistics. Some existing scheduling middle-wares are not efficient as they assume Task completion signal: After successful execution of task, Performance Monitor signals the Reward Calculator (sub-module of QL Scheduler and Load balancer) in the form of task completion time. Average distribution of tasks for Resource R. Task Analyzer shows the distribution and run time performance of tasks We propose a Q-learning algorithm to solve the problem of scheduling shared EVs to maximize the global daily income. To repeatedly adjust in response to a dynamic environment, they will need the adaptability that only machine learning can offer. be seen from these graphs that the proposed approach performs better than the comparison of QL Scheduling vs. Other Scheduling with increasing number In RL, an agent learns by interacting with its environment and tries to maximize its long term return by performing actions and receiving rewards as shown in Fig. of processors for 10000 Episodes, Cost They proposed a new algorithm called Exploring Selfish Reinforcement Learning (ESRL) based on 2 phases, exploration and synchronization phase. performance improvements by increasing Learning. In this scheme, a deep‐Q learning‐based heterogeneous earliest‐finish‐time (DQ‐HEFT) algorithm is developed, which closely integrates the deep learning mechanism with the task scheduling heuristic HEFT. To optimize the overall control performance, we propose the following sequential design of Under more difficult conditions, its performance is significantly and disproportionately reduced. The Log Generator saves the collected information of each grid node and executed tasks information. Present work is the enhancement of this technique. 1 A Double Deep Q-learning Model for Energy-efficient Edge Scheduling Qingchen Zhang, Member, IEEE, Man Lin, Senior Member, IEEE, Laurence T. Yang, Senior Member, IEEE, Zhikui Chen, Samee U. Khan, Senior Member, IEEE, and Peng Li Abstract—Reducing energy consumption is a vital and challenging problem for the edge computing devices since they are always energy-limited. and communication of resources. Thus, a Q-learning algorithm for task scheduling based on Improved Support Vector Machine (ISVM) in WSNs, called ISVM-Q, is proposed to optimize the application performance and energy consumption of networks. [2] pro-posed an intelligent agent-based scheduling system. One expects to start with a high learning rate, which allows fast changes and lowers the learning rate as time progresses. In this regard, the use of Reinforcement Learning is more precise and potentially computationally cheaper than other approaches. d, e are constants determining the weight of each contribution from history Present proposed technique also handles load distribution overhead which is the major cause of performance degradation in traditional dynamic schedulers. We use the following (optimal) design strategy: First, we synthesize an optimal controller for each subsystem; next, we design a learning algorithm that adapts to the chosen … A weighted Q-learning algorithm based on clustering and dynamic search was … We formulate the scheduling of shared EVs in the framework of Markov decision process. A New Deep-Q-Learning-Based Transmission Scheduling Mechanism for the Cognitive Internet of Things Abstract: Cognitive networks (CNs) are one of the key enablers for the Internet of Things (IoT), where CNs will play an important role in the future Internet in several application scenarios, such as healthcare, agriculture, environment monitoring, and smart metering. 4 show the execution time comparison of different selected resources. Multi-agent technique provides the benefit of scalability and robustness and learning leads the system to learn based on its past experience and generate better results over time using limited information. and load balancing problem and extension of Galstyan et al. to get maximum throughput. Even though considerable attention has been given to the issues of load balancing and scheduling in the distributed heterogeneous systems, few researchers have addressed the problem from the view point of learning and adaptation. The action of Q-learning with the highest expected Q value is selected in each state to update Q value, in which more accumulated … Aim: To optimize average job-slowdown or job completion time. by handling co-allocation. “Flow-shop Scheduling Based on Reinforcement Learning Algorithm.” Journal of Production Systems and Information Engineering, A Publication of the University of Miskolc 1: 83–90. In future we will enhance this technique using SARSA algorithm, another recent form of Reinforcement Learning. Co-Scheduling is done by the Task Mapping Engine on the basis of cumulative Q-value of agents. In FAC, iterates are scheduled in batches, where the size of a batch is a fixed ratio of the unscheduled iterates and the batch is divided into P chunks (Hummel et al., 1993). However, Q-tables are difficult to solve for high-dimensional continuous state or action spaces. OªWEy6%ñ„ŠFBé‹i¡¦ü`Ã_̪Q„Ûõj PÐ It is adaptive version of Reinforcement Learning and does The Q-Value Calculator follows the Q-Learning algorithm to calculate Q-value Now we will converge specifically towards multi-agent RL techniques. The workflowsim simulator is used for the experiment of the real‐world and synthetic workflows. A further challenge to load balancing lies in the lack of accurate resource Load balancing attempts to ensure that the workload on each host is within a balance criterion of the workload present on every other host in the system. handles user requests for task execution and communication with the grid. These algorithms are touted as the future of Machine Learning as these eliminate the cost of collecting and cleaning the data. Process redistribution cost and reassignment time is high in case of non-adaptive Verbeeck et al. Experiments were conducted for a different number of processors, episodes and task input sizes. The state is given as the input and the Q-value of all possible actions is generated as the output. Instead, it redistributes the tasks from heavily loaded processors to lightly loaded ones based on the information collected at run-time. The results showed considerable improvements upon a static load balancer. State of the art techniques uses Deep neural networks instead of the Q-table (Deep Reinforcement Learning). Heterogeneous systems have been shown to produce higher performance for lower cost than a single large machine. Given the dynamic and uncertain production environment of job shops, a scheduling strategy with adaptive features must be developed to fit variational production factors. The results obtained from these comparisons Therefore, a dynamic scheduling system model based on multi-agent technology, including machine, buffer, state, and job agents, was built. γ is discount factor.
