  1. 1. Queryable Workflows: Extending Dataflow Streaming with Dynamic Request/Reply Communication

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Chengyang Huang; [2023]
    Keywords : Stream Processing; Observability; SQL Query Engine; Stateful Serverless; Searbetning av Strömmar; Observabilitet; SQL-förfrågningsmotor; Stateful Serverless;

    Abstract : Stream processing systems have been widely adopted in applications such as recommendation systems, anomaly detection, and system monitoring due to their real-time capabilities. Improving observability in stream processing systems can further expand their application scenarios, including the implementation of stateful serverless applications. READ MORE

  3. 2. Serverless Streaming Graph Analytics with Flink Stateful Functions

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sihan Chen; [2022]
    Keywords : Temporal Graph; Graph Analytics; Flink Stateful Functions; Serverless; FaaS;

    Abstract : Serverless Function as a Service (FaaS) platforms have been an emerging trend nowadays with the continuous improvement of the cloud-native ecosystem. Graph streaming analytics is a widely-known research area that demands well-designed computation paradigms and complex optimization of storage and queries. READ MORE

  4. 3. A latency comparison in a sharded database environment : A study between Vitess-MySQL and CockroachDB

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

    Author : Filip Lundh; Mikael Mohlin; [2022]
    Keywords : Architecture Analysis; CockroachDB; Database Management System; Distributed SQL; Latency Comparison; MySQL; NewSQL; Sharding; Source Code Inspection; Vitess;

    Abstract : The world is becoming more and more digitized which in turn puts pressure on existing applications and systems to be able to handle large quantities of data. And  in some cases, that data also needs to be operated in secure and isolated environments. To address these needs, a new category  of databases has emerged, by the name of NewSQL. READ MORE

  5. 4. Explainable Reinforcement Learning for Risk Mitigation in Human-Robot Collaboration Scenarios

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alessandro Iucci; [2021]
    Keywords : Explainable Reinforcement Learning; Human-Robot Collaboration; Risk Mitigation; Reward Decomposition; Autonomous Policy Explanation; Collaborative Robots; Förklarbar förstärkningslärande; Mänskligt-robot-samarbete; Riskreducering; Reward Decomposition; Autonomous Policy Explanation; Samarbetsrobotar;

    Abstract : Reinforcement Learning (RL) algorithms are highly popular in the robotics field to solve complex problems, learn from dynamic environments and generate optimal outcomes. However, one of the main limitations of RL is the lack of model transparency. This includes the inability to provide explanations of why the output was generated. READ MORE

  6. 5. Natural Language Understanding for Multi-Level Distributed Intelligent Virtual Sensors

    University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

    Author : Angelos Papangelis; Georgios Kyriakou; [2021]
    Keywords : internet of things; virtual sensing; dataset generation; deep learning; natural language understanding;

    Abstract : In our thesis we explore the Automatic Question/Answer Generation (AQAG) and the application of Machine Learning (ML) in natural language queries. Initially we create a collection of question/answer tuples conceptually based on processing received data from (virtual) sensors placed in a smart city. READ MORE
