Talk: 从零开始构建食品机器人：自动化与AI的结合

  • Speaker: Xiaofeng Guo （郭晓峰）

本次活动中，我们会介绍以下我们这个食品机器人项目的实现过程（包括我们之前失败的经历），以及如何逐步将人工智能（AI）技术应用于其中。在这个项目中，我们尝试实现一个高效的食品自动化解决方案，以降低人工成本，提高生产效率，最终为消费者提供更好的产品和服务体验。我们经历了机械设计、硬件开发、固件实现、顶层控制+AI等等的工作，基本堆出来了第一代机器，并收集了一些数据。目前一方面在迭代这个机器，一方面逐步引入AI，以提升机器的精度和效率。

对于这方面目前的状态，我们会讨论一下近期比较流行的，主要基于robomimic平台的模拟学习方案；以及我们觉得非常强大的基于模拟的强化学习解决方案。如果大家有这方面的项目经验，欢迎来meetup上交流，也欢迎在后续的meetup上介绍给大家。同样，在机械和硬件的实现过程中，我们对于工具的匮乏深感痛苦。由于目前设计工具无法用某种编程语言的方式进行描述，导致这方面无法引入类似chatgpt这样的强AI的状态上。这个会是我们的长期目标，有兴趣的同学也可以来贡献你们的想法。

Talk1: 如何把Alerts减少两个数量级: EA数据平台在云端运维的探索与演进

Abstract: Today, one can easily launch or terminate services with hundreds or thousands of compute instances in just a few seconds on cloud services such as AWS. However, operating, monitoring and maintaining those resources could also easily become a nightmare if the corresponding tooling systems were not designed in a cloud-native way.

Detail: In this talk, we share our lessons in building and rebuilding a cloud-native monitoring system to solve this problem at Electronic Arts (EA). In the first generation of the monitoring system, configurations were manually created for many individual software components and spread over all the resources. As services were started and terminated rapidly over time, it was extremely difficult to keep all the configurations up to date. Consequently, on average we received over 1,000 alerts from thousands of machines on a daily basis, which stressed the operations team. We redesigned the system in late 2018 in a project called Monitoring As Code (MAC) emphasizing on version control and automation. MAC manages all the configurations using a GIT project in the same way as software code. Moreover, it establishes standards so that the configurations are automatically generated and deployed to keep everything in sync. As a result, it reduced the daily average number of alerts by two orders of magnitude. A big data problem is reduced to a small data problem for human productivity and operational efficiency.

Speaker Bio: The speaker, Du Li, is currently an Architect of Big Data Infrastructure at Electronic Arts. He earned his BS from Wuhan University, MS from Peking University, and PhD from UCLA. He worked in academia and industrial labs for many years. Prior to joining EA in mid-2018, he worked at Yahoo and Apple as a senior software engineer.

Talk2: 基于Raft,gRPC,RocksDB和高并发算法打造存储10亿个文件的高效元数据服务

Abstract: 起源于UC Berkeley AMPLab的Alluxio是一个被百度、腾讯、华为、沃尔玛、Twosigma等行业巨头在云端广泛应用的开源数据编排系统。它的设计初衷之一包括能够高效存储并服务超大规模的文件系统中所有文件和目录的元数据。

Detail: 本演讲将分享Alluxio元数据服务（master节点）的架构，实现和优化，以解决可扩展性挑战。我们将特别介绍如何设计和应用合多个前沿工程技术和实践，包括基于堆外KV store RocksDB实现分层级的元数据存储，细粒度文件系统inode树锁方案，基于Raft分布式共识协议的master多节点高可用方案，以及社区对gRPC系统的探索和实践。结合上述技术，Alluxio 2.0的元数据服务能够存储至少10亿个文件，并在显着降低内存需求的同时扩展到3000个worker节点并为30000个客户端提供服务。

Speaker Bio: 范斌是Alluxio公司的创始成员与, Alluxio开源项目的PMC成员. 加入Alluxio团队前, 范斌在Google从事下一代大规模分布式存储系统的研究与开发. 范斌博士毕业于卡内基梅隆大学计算机系, 博士期间在分布式系统算法和系统实现等方向发表多篇包括SIGCOMM, SOSP, NSDI等顶级论文, 设计和实现了CuckooFilter，MemC3以及libCuckoo.
