  1. 1. Compression Selection for Columnar Data using Machine-Learning and Feature Engineering

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

    Author : Douglas Persson; Ludvig Juelsson Larsen; [2023]
    Keywords : Machine Learning; XGBoost; Classification; Feature Engineering; Compression Algorithms; Data Encodings; Database Management System DBMS ; Column- Oriented DBMS;

    Abstract : There is a continuously growing demand for improved solutions that provide both efficient storage and efficient retrieval of big data for analytical purposes. This thesis researches the use of machine-learning together with feature engineering to recommend the most cost-effective compression algorithm and encoding combination for columns in a columnar database management system (DBMS).

  2. 2. Comparison of lossy and lossless compression algorithms for time series data in the Internet of Vehicles

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Joseph Hughes; [2023]
    Keywords : Data compression; Lossy compression; Lossless compression; Time series; Internet of Vehicles;

    Abstract : As automotive development advances, connectivity features are continually added to vehicles that, in conjunction, form an Internet of Vehicles. For numerous reasons, it is vital for vehicle manufacturers to collect telemetry from their fleets. READ MORE

  3. 3. Compression's effect on end-to-end latency in file upload systems that utilize encryption

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Kristoffer Zaar; [2023]
    Keywords : Encryption; Compression; Latency; Web-Based systems;

    Abstract : Encryption is the process of obfuscating data to restrict access to it while allowing it to be returned to its original non-obfuscated form through decryption. This process is increasingly used within web-based systems to secure data. READ MORE

  4. 4. Compression of Large-Scale Aerial Imagery : Exploring Set Redundancy Methods

    University essay from Högskolan i Gävle/Datavetenskap

    Author : Solvej Lüdeking; [2023]
    Keywords : Set redundancy; image compression; aerial imagery;

    Abstract : Compression of data has been historically always important; more data is gettingproduced and therefore has to be stored. While hardware technology advances,compression should be a must to reduce storage occupied and to keep the data intransmission as small as possible. READ MORE

  5. 5. Content Based Video Encoding Based on Spatial and TemporalInformation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Theofanis Papakonstantinou; [2023]
    Keywords : ;

    Abstract : A significant amount of video content is produced today that needs to be stored, distributed, andstreamed globally in a cost-effective way. This relies on video compression, a process performedby encoding software that remove spatial redundancy, the similarities within a frame, andtemporal redundancy, the similarities between temporarily adjacent frames.
