MoralBERT: Detecting Moral Values in Social Discourse

no code implementations12 Mar 2024 Vjosa Preniqi, Iacopo Ghinassi, Kyriaki Kalimeri, Charalampos Saitis

Experiments in an out-of-domain setting, instead, suggest that further work is needed for existing domain adaptation techniques to generalise between different social media platforms, especially for the multi-label task.

Composer Style-specific Symbolic Music Generation Using Vector Quantized Discrete Diffusion Models

no code implementations21 Oct 2023 Jincheng Zhang, Jingjing Tang, Charalampos Saitis, György Fazekas

The diffusion model is trained to generate intermediate music sequences consisting of codebook indexes, which are then decoded to symbolic music using the VQ-VAE's decoder.

The Responsibility Problem in Neural Networks with Unordered Targets

no code implementations19 Apr 2023 Ben Hayes, Charalampos Saitis, György Fazekas

We discuss the discontinuities that arise when mapping unordered objects to neural network outputs of fixed permutation, referred to as the responsibility problem.

The language of sounds unheard: Exploring musical timbre semantics of large language models

no code implementations16 Apr 2023 Kai Siedenburg, Charalampos Saitis

ChatGPT generated semantic profiles that only partially correlated with human ratings, yet showed robust agreement along well-known psychophysical dimensions of musical sounds such as brightness (bright-dark) and pitch height (deep-high).

"More Than Words": Linking Music Preferences and Moral Values Through Lyrics

1 code implementation2 Sep 2022 Vjosa Preniqi, Kyriaki Kalimeri, Charalampos Saitis

This study explores the association between music preferences and moral values by applying text analysis techniques to lyrics.

Deep Conditional Representation Learning for Drum Sample Retrieval by Vocalisation

1 code implementation10 Apr 2022 Alejandro Delgado, Charalampos Saitis, Emmanouil Benetos, Mark Sandler

Imitating musical instruments with the human voice is an efficient way of communicating ideas between music producers, from sketching melody lines to clarifying desired sonorities.

Representation Learning Retrieval

Deep Embeddings for Robust User-Based Amateur Vocal Percussion Classification

no code implementations10 Apr 2022 Alejandro Delgado, Emir Demirel, Vinod Subramanian, Charalampos Saitis, Mark Sandler

Vocal Percussion Transcription (VPT) is concerned with the automatic detection and classification of vocal percussion sound events, allowing music creators and producers to sketch drum lines on the fly.

Timbre Transfer with Variational Auto Encoding and Cycle-Consistent Adversarial Networks

1 code implementation5 Sep 2021 Russell Sammut Bonnici, Charalampos Saitis, Martin Benning

This research project investigates the application of deep learning to timbre transfer, where the timbre of a source audio can be converted to the timbre of a target audio with minimal loss in quality.

Neural Waveshaping Synthesis

1 code implementation11 Jul 2021 Ben Hayes, Charalampos Saitis, György Fazekas

We present the Neural Waveshaping Unit (NEWT): a novel, lightweight, fully causal approach to neural audio synthesis which operates directly in the waveform domain, with an accompanying optimisation (FastNEWT) for efficient CPU inference.
