  1. 1. Efficient Music Thumbnailing for Genre Classification

    University essay from KTH/Matematisk statistik

    Author : Adam Skärbo Jonsson; [2022]
    Keywords : Music thumbnailing; Music genre classification; Machine learning; Deep learning; Bidirectional recurrent neural network; RNN; Musikgenreklassificering; Maskininlärning; Djupinlärning; RNN;

    Abstract : For music genre classification purposes, the importance of an intelligent and content-based selection of audio samples has been mostly overlooked. One common approach toward representative results is to select samples at predetermined locations. This is done to avoid analysis of the full audio during classification. READ MORE

  6. 5. Development of Scoring Algorithm for Karaoke Computer Games

    University essay from KTH/Signalbehandling

    Author : Dongping Qiu; [2012]
    Keywords : ;

    Abstract : In a Karaoke computer game, the users receive a score as a measure of their performance. A music recognition system estimates the underlying music notes the users have performed. Many developed approaches use deterministic signal processing. This thesis builds statistical hidden markov models (HMM) to be used in scoring. READ MORE
