  1. 1. Continuous Parallel Approximate Frequent Elements Queries on Data Streams

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Victor Jarlow; [2021-10-06]
    Keywords : computer science; big data; Space-Saving; Misra-Gries summary; frequent items; frequent elements; concurrent programming; Delegation Sketch; domain splitting; Count-Min Sketch; Majority algorithm; pproximate frequent-elements algorithm; approximate top-k elements algorithm;

    Abstract : The frequent elements problem involves processing a stream of elements and finding all elements that occur more than a given fraction of the time. A relaxed version of this problem is the -approximate elements problem which allows some false positives. READ MORE

  3. 2. Enhancing decision tree accuracy and compactness with improved categorical split and sampling techniques

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

    Author : Gaëtan Millerand; [2020]
    Keywords : ;

    Abstract : Decision tree is one of the most popular algorithms in the domain of explainable AI. From its structure, it is simple to induce a set of decision rules which are totally understandable for a human. That is why there is currently research on improving decision or mapping other models into a tree. Decision trees generated by C4. READ MORE

  4. 3. Cloud native design of IoT baseband functions : Introduction to cloud native principles

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

    Author : Lalith Kumar Bakthavathsalu; [2020]
    Keywords : Cloud-native; Gateway; GNU Radio; IoT; LoRa; LPWAN; Software-Defined Radio; Cloud-native; Gateway; GNU Radio; IoT; LoRa; LPWAN; Software-Defined Radio;

    Abstract : The exponential growth of research and deployment of 5G networks has led to an increased interest in massive Machine Type Communications (mMTC), as we are on the quest to connect all devices. This can be attributed to the constant development of long-distance and low-powered Internet-of- Things (IoT) technologies, or, Low Power Wide Area Network (LPWAN) technologies such as Long-Range (LoRa) and Narrow Band- IoT (NB-IoT).

  5. 4. Uplift Modeling : Identifying Optimal Treatment Group Allocation and Whom to Contact to Maximize Return on Investment

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Henrik Karlsson; [2019]
    Keywords : Causal Effect; Uplift Modeling; Class Transformation Method; Model Uplift Directly; Random Forest; XGBoost; Qini Curve; Qini Coefficient; Optimal Control Group Allocation;

    Abstract : This report investigates the possibilities to model the causal effect of treatment within the insurance domain to increase return on investment of sales through telemarketing. In order to capture the causal effect, two or more subgroups are required where one group receives control treatment. READ MORE

  6. 5. Multi-scale modelling of fire in accelerator tunnels: a CERN case study

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Melchior Schepers; [2018]
    Keywords : Multi-scale modelling; CFD; tunnel fires; FDS; CERN; particle accelerator; Technology and Engineering;

    Abstract : Multi-scale modellering is een nieuwe benadering in het modelleren van rook en brand in systemen waarbij de grootte van het domein een meer conventionele volledige 3D modellering onmogelijk maakt. Het domein wordt opgesplitst in een 1D en 3D gedeelte om zo de simulatietijd te verminderen. READ MORE
