Large Vocabulary Automatic Chord Estimation with an Even Chance Training Scheme
نویسندگان
چکیده
This paper presents a large vocabulary automatic chord estimation system implemented using a bidirectional long short-term memory recurrent neural network trained with a skewed-class-aware scheme. This scheme gives the uncommon chord types much more exposure during the training process. The evaluation results indicate that: compared with a normal training scheme, the proposed scheme can boost the weighted chord symbol recalls of some uncommon chords and significantly improve the average chord quality accuracy, at the expense of the overall weighted chord symbol recall.

A Hybrid Gaussian-HMM-Deep Learning Approach for Automatic Chord Estimation with Very Large Vocabulary
We propose a hybrid Gaussian-HMM-Deep-Learning approach for automatic chord estimation with very large chord vocabulary. The Gaussian-HMM part is similar to Chordino, which is used as a segmentation engine to divide input audio into note spectrogram segments. Two types of deep learning models are proposed to classify these segments into chord labels, which are then connected as chord sequences....

In this paper, we propose a new system design framework for large vocabulary automatic chord estimation. Our approach is based on an integration of traditional sequence segmentation processes and deep learning chord classification techniques. We systematically explore the design space of the proposed framework for a range of parameters, namely deep neural nets, network configurations, input fea...
متن کاملUsing Hyper-genre Training to Explore Genre Information for Automatic Chord Estimation
Recently a large amount of new chord annotations have been made available. This raises hopes for further development in automatic chord estimation. While more data seems to imply better performance, a major challenge however, is the wide variety of genres covered by these new data. As a result, the genre-independent training scheme as is common today is bound to fail. In this paper we investiga...
متن کاملFour Timely Insights on Automatic Chord Estimation
Automatic chord estimation (ACE) is a hallmark research topic in content-based music informatics, but like many other tasks, system performance appears to be converging to yet another glass ceiling. Looking toward trends in other machine perception domains, one might conclude that complex, data-driven methods have the potential to significantly advance the state of the art. Two recent efforts d...
متن کاملChord Label Personalization through Deep Learning of Integrated Harmonic Interval-based Representations
The increasing accuracy of automatic chord estimation systems, the availability of vast amounts of heterogeneous reference annotations, and insights from annotator subjectivity research make chord label personalization increasingly important. Nevertheless, automatic chord estimation systems are historically exclusively trained and evaluated on a single reference annotation. We introduce a first...
