    University essay from Stockholms universitet/Statistiska institutionen

    Author : Alice Jonason; [2023]
    Keywords : Recommender systems; Content-based systems; Implicit ratings; Latent Dirichlet Allocation; Vector Space Model;

    Abstract : This thesis addresses the new item problem in recommender systems, which pertains to the challenges of providing personalized recommendations for items which have limited user interaction history. The study proposes and evaluates a method for generating personalized recommendations for movies, shows, and series on one of Sweden’s largest streaming platforms. READ MORE

  3. 2. Evaluating Cold-Start in Recommendation Systems Using a Hybrid Model Based on Factorization Machines and SBERT Embeddings

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

    Author : Sabrina Chowdhury; [2022]
    Keywords : Natural Language Processing; Hybrid Recommender Systems; Cold-Start Problem; språkteknologi; hybrida rekommendationssystem; kallstartsproblemet;

    Abstract : The item cold-start problem, which describes the difficulty of recommendation systems in recommending new items to users, remains a great challenge for recommendation systems that rely on past user-item interaction data. A popular technique in the current research surrounding the cold-start problem is the use of hybrid models that combine two or more recommendation strategies that may contribute with their individual advantages.

  4. 3. New object grasp synthesis with gripper selection: process development

    University essay from Jönköping University/JTH, Avdelningen för datavetenskap

    Author : Tanguy Legrand; [2022]
    Keywords : grasps pose synthesis; point cloud classification; point cloud regression; machine learning; 3D model; CAD model; robotic grasping; pick and place; gripper selection;

    Abstract : A fundamental aspect to consider in factories is the transportation of the items at differentsteps in the production process. Conveyor belts do a great to bring items from point A topoint B but to load the item onto a working station it can demands a more precise and,in some cases, delicate approach. READ MORE
