In this article, we introduce a novel Multitask method based on Knowledge Transfer in cooperative MARL (MKT-MARL). By learning from task-specific teachers, our approach empowers a single team of agents to attain expert-level performance in multiple tasks. MKT-MARL utilizes a knowledge distillation algorithm specifically designed for the multiagent architecture, which rapidly learns a team control policy incorporating common coordinated knowledge from the experience of task-specific teachers. In addition, we enhance this training with teacher annealing, gradually shifting the model's learning from distillation toward environmental rewards. This enhancement helps the multitask model surpass its single-task teachers. We extensively evaluate our algorithm using two commonly-used benchmarks: \u0000<italic>StarCraft II</i>\u0000 micromanagement and multiagent particle environment. The experimental results demonstrate that our algorithm outperforms both the single-task teachers and a jointly trained team of agents. Extensive ablation experiments illustrate the effectiveness of the supervised knowledge transfer and the teacher annealing strategy.","PeriodicalId":55977,"journal":{"name":"IEEE Transactions on Games","volume":"16 3","pages":"566-576"},"PeriodicalIF":1.7,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135554802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We manually analyze the game reviews wrongly classified by OPT-175B to better understand the issues that affect the performance of that model and how those issues compare to the challenges faced by traditional classifiers.

During the interactions, the uncertainty of environment and reward will inevitably induce stochasticity in the long-term returns, and the randomness can be exacerbated with the increasing number of agents. However, such randomness is ignored by most of the existing value-based multi-agent reinforcement learning (MARL) methods, which only model the expectation of \u0000<inline-formula><tex-math>$Q$</tex-math></inline-formula>\u0000-value for both the individual agents and the team. Compared to using the expectations of the long-term returns, it is preferable to directly model the stochasticity by estimating the returns through distributions. With this motivation, this article proposes a novel value-based MARL framework from a distributional perspective, i.e., parameterizing value function via \u0000<underline>M</u>\u0000ixture of \u0000<underline>C</u>\u0000ategorical distributions for MARL (MCMARL). Specifically, we model both the individual and global \u0000<inline-formula><tex-math>$Q$</tex-math></inline-formula>\u0000-values with categorical distribution. To integrate categorical distributions, we define five basic operations on the distribution, which allow the generalization of expected value function factorization methods (e.g., value decomposition networks (VDN) and QMIX) to their MCMARL variants. We further prove that our MCMARL framework satisfies the \u0000<italic>Distributional-Individual-Global-Max</i>\u0000 principle with respect to the expectation of distribution, which guarantees the consistency between joint and individual greedy action selections in the global and individual \u0000<inline-formula><tex-math>$Q$</tex-math></inline-formula>\u0000-values.

However, unlike single-goal agents, multigoal agents struggle to break through the exploration bottleneck with a fair share of interactions, owing to rarely reusable goal-oriented experiences with sparse goal-reaching rewards. Therefore, well-arranged behavior goals during training are essential for multigoal agents, especially in long-horizon tasks. To this end, we propose efficient multigoal exploration on the basis of maximizing the entropy of successor features and Exploring entropy-regularized successor matching, namely, E\u0000<inline-formula><tex-math>$^{2}$</tex-math></inline-formula>\u0000SM.

However, the exponentially growing joint-action space severely challenges the critic's value evaluation and hinders performance of MAPG methods. To address this issue, we augment Central-Q policy gradient with a joint-action embedding function and propose mutual-information maximization MAPG (M3APG). The joint-action embedding function makes joint-actions contain information of state transitions, which will improve the critic's generalization over the joint-action space by allowing it to infer joint-actions' outcomes. We theoretically prove that with a fixed joint-action embedding function, the convergence of M3APG is guaranteed.

State-of-the-art exploration methods address this challenge by utilizing intrinsic rewards to guide exploration in uncertain environment dynamics or novel states. However, these methods fall short in procedurally-generated environments, where the agent is unlikely to visit a state more than once due to the different environments generated in each episode. Recently, imitation-learning-based exploration methods have been proposed to guide exploration in different kinds of procedurally-generated environments by imitating high-quality exploration episodes. However, these methods have weaker exploration capabilities and lower sample efficiency in complex procedurally-generated environments. Motivated by the fact that demonstrations can guide exploration in sparse reward environments, we propose improved exploration with demonstrations (IEWD), an improved imitation-learning-based exploration method in procedurally-generated environments, which utilizes demonstrations from these environments. IEWD assigns different episode-level exploration scores to each demonstration episode and generated episode. IEWD then ranks these episodes based on their scores and stores highly-scored episodes into a small ranking buffer. IEWD treats these highly-scored episodes as good exploration episodes and makes the deep RL agent imitate exploration behaviors from the ranking buffer to reproduce exploration behaviors from good exploration episodes. Additionally, IEWD adopts the experience replay buffer to store generated positive episodes and demonstrations and employs self-imitating learning to utilize experiences from the experience replay buffer to optimize the policy of the deep RL agent. We evaluate our method IEWD on several procedurally-generated MiniGrid environments and 3-D maze environments from MiniWorld. The results show that IEWD significantly outperforms existing learning from demonstration methods and exploration methods, including state-of-the-art imitation-learning-based exploration methods, in terms of sample efficiency and final performance in complex procedurally-generated environments.","PeriodicalId":55977,"journal":{"name":"IEEE Transactions on Games","volume":"16 3","pages":"530-543"},"PeriodicalIF":1.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62570339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
