  • Chord-aware automatic music transcription based on hierarchical Bayesian integration of acoustic and language models

    Ojima Yuta , Nakamura Eita , Itoyama Katsutoshi , Yoshii Kazuyoshi

    … Since chords and musical notes are deeply linked with each other, we propose joint pitch and chord estimation based on a Bayesian hierarchical model that consists of an acoustic model representing the generative process of a spectrogram and a language model representing the generative process of a piano roll. … The language model is formulated as a hidden Markov model that has chord labels as the latent variables and emits a piano roll. …

  • On the Construction of Translation in Partial Bidirectionalization

    Soichiro Hidaka , Massimo Tisi

    … In our previous work, we have proposed a general framework of partially translating UX languages to BX ones to fully maintain the expressive power of the UX languages while allowing backpropagable updates on a part of target models. … In an additive transformation language, sequences of language constructs at different level of well-defined syntactic hierarchy in a transformation can be shorten to produce smaller outputs. …
