This ICLR 2018 accepted paper, Deep Mean Field Games for Learning Optimal Behavior Policy of Large Populations, deals with inference in models of collective behavior, specifically at how to infer the parameters of a mean field game (MFG) representation of collective behavior. This paper is authored by Jiachen Yang, Xiaojing Ye, Rakshit Trivedi, Huan Xu, and Hongyuan Zha. The 6th annual ICLR conference is scheduled to happen between April 30 - May 03, 2018. Mean field game theory is the study of decision making in very large populations of small interacting agents. This theory understands the behavior of multiple agents each individually trying to optimize their position in space and time, but with their preferences being partly determined by the choices of all the other agents. Estimating the optimal behavior policy of large populations with Deep Mean Field Games What problem is the paper attempting to solve? The paper considers the problem of representing and learning the behavior of a large population of agents, to construct an effective predictive model of the behavior. For example, a population’s behavior directly affects the ranking of a set of trending topics on social media, represented by the global population distribution over topics. Each user’s observation of this global state influences their choice of the next topic in which to participate, thereby contributing to future population behavior. Classical predictive methods such as time series analysis are also used to build predictive models from data. However, these models do not consider the behavior as the result of optimization of a reward function and so may not provide insight into the motivations that produce a population’s behavior policy. Alternatively, methods that employ the underlying population network structure assume that nodes are only influenced by a local neighborhood and do not include a representation of a global state. Hence, they face difficulty in explaining events as the result of uncontrolled implicit optimization. MFG (mean field games) overcomes the limitations of alternative predictive methods by determining how a system naturally behaves according to its underlying optimal control policy. The paper proposes a novel approach for estimating the parameters of MFG. The main contribution of the paper is in relating the theories of MFG and Reinforcement Learning within the classic context of Markov Decision Processes (MDPs). The method suggested uses inverse RL to learn both the reward function and the forward dynamics of the MFG from data. Paper summary The paper covers the problem in three sections-- theory, algorithm, and experiment.  The theoretical contribution begins by transforming a continuous time MFG formulation to a discrete time formulation and then relates the MFG to an associated MDP problem. In the algorithm phase, an RL solution is suggested to the MFG problem. The authors relate solving an optimization problem on an MDP of a single agent with solving the inference problem of the (population-level) MFG. This leads to learning a reward function from demonstrations using a maximum likelihood approach, where the reward is represented using a deep neural network. The policy is learned through an actor-critic algorithm, based on gradient descent with respect to the policy parameters. The algorithm is then compared with previous approaches on toy problems with artificially created reward functions. The authors then demonstrate the algorithm on real-world social data with the aim of recovering the reward function and predicting the future trajectory. Key Takeaways This paper describes a data-driven method to solve a mean field game model of population evolution, by proving a connection between Mean Field Games with Markov Decision Process and building on methods in reinforcement learning. This method is scalable to arbitrarily large populations because the Mean Field Games framework represents population density rather than individual agents. With experiments on real data, Mean Field Games emerges as a powerful framework for learning a reward and policy that can predict trajectories of a real-world population more accurately than alternatives. Reviewer feedback summary Overall Score: 26/30 Average Score: 8.66 The reviewers are unanimous in finding the work in this paper highly novel and significant. According to the reviewers, there is still minimal work at the intersection of machine learning and collective behavior, and this paper could help to stimulate the growth of that intersection. On the flip side, surprisingly, the paper was criticized with the statement “scientific content of the work has critical conceptual flaws”. However, the author refutations persuaded the reviewers that the concerns were largely addressed.

Cloud TPUs available in beta, Microsoft’s plans for blockchain, Oracle’s PaaS, Scanpy, and more in today’s top stories around machine learning, blockchain, and data science news. 1. Google’s Cloud TPUs now available in beta for accelerating machine learning Google’s Cloud TPUs, the family of Google-designed hardware accelerators, is now available in beta. These custom chips are optimized to speed up and scale up specific ML workloads programmed with TensorFlow. The company first announced Cloud TPUs at its I/O developer conference on May 17-19, 2017,  for a limited number of developers and researchers. Each Cloud TPU features four custom ASICs. It packs up to 180 teraflops of floating-point performance and 64 GB of high-bandwidth memory onto a single board. Developers who already use TensorFlow don’t have to make any major changes to their code to use this service. Usage will be billed at $6.50 per Cloud TPU per hour. Using a single Cloud TPU, developers can train ResNet-50 to the expected accuracy on the ImageNet benchmark challenge in less than a day, for well under $200! Once the TPU pods (array of cloud TPUs connected together via an ultra-fast, dedicated network to form multi-petaflop ML supercomputers) are available, ResNet-50 and Transformer training times will drop from almost a day to less than 30 minutes. 2. Microsoft plans to use blockchain technology for identity management In a recent blog post, Microsoft revealed plans to use blockchain technology in the form of decentralized identity systems to solve online management issues with personal data and identity management. A decentralized identity system is not controlled by any single, centralized institution. It removes the possibility of censorship and gives an individual full control over their identity and reputation. The building of the platform takes inspiration from Microsoft’s commitment to the ID2020 alliance. Initially, Microsoft will support blockchain-based decentralized IDs (DIDs) through the Microsoft Authenticator app. Microsoft plans to work with DID method implementations, which follow a specific standard outlined by a W3C working group. According to Ankur Patel, PM, Microsoft’s identity division, “Using our technology individuals will get a secure encrypted digital hub where they can store their identity data and easily control access to it.” 3.  Oracle adds advanced autonomous capabilities to its Cloud platform Oracle lays out a  broader vision for Oracle Cloud Platform with a range of autonomous service capabilities. Oracle PaaS (Platform as a service) capabilities support the needs of the entire organization, including developers, enterprise architects, data scientists, IT operations, and business users. Autonomous PaaS services include advanced capabilities such as auto code generation, self-defining data flows, automated data discovery and preparation. They also have voice-enabled integration links, machine learning-based continuous data analysis, and self-learning bots that understand user intent and continually refine that understanding. They will speed IT deployments, by letting developers jump right to creating new functionality rather than having to spend time on the routine tasks. PaaS promises to lower IT costs and improve security because they require less human management and eliminate human error. 4. Scientists develop Scanpy to help manage enormous datasets Scientists from the Helmholtz Zentrum München have developed Scanpy, a program that is able to help manage enormous datasets. Scanpy was made with the purpose of analyzing the gene-expression data of a large number of individual cells. It allows comprehensive analysis of large gene-expression datasets with a broad range of machine-learning and statistical methods. Scanpy is based on the Python language and uses graph-like coordinate system. Instead of characterizing a single cell by the expression value for thousands of genes, the system simply characterizes cells by identifying their closest neighbors -- very much like the connections in social networks. In fact, to identify cell types, Scanpy uses the same algorithms as Facebook does for identifying communities. To read more, visit the official documentation. 5. Accelirate has announced its partnership with Chirrp.ai to strengthen its enterprise-class chatbot solutions capability Accelirate has partnered with Chirrp.ai, an AI-powered communication channel provider, to strengthen their chatbot solutions. With this partnership, the enterprise-grade chatbots will be able to handle low-, medium- and high-complexity use cases. A high-complexity use case is where many clients use chatbots as an NLP/NLU-powered application-delivery mechanism which can handle complex user queries as well as application rules and workflows right from within the chatbot interface. Initially, the chatbots will be configured and set up to understand structured as well as unstructured customer queries and provide them with appropriate answers without involving a human. The chatbot will gather the relevant customer information, query the backend systems (which can be accomplished by using RPA robots) and present the information to the customer interactively. All without human intervention!
