Symbols are not uniquely human [PDF]

open access: yes, 2006
Modern semiotics is a branch of logics that formally defines symbol-based communication. In recent years, the semiotic classification of signs has been invoked to support the notion that symbols are uniquely human.

Generalization in birdsong classification: impact of transfer learning methods and dataset characteristics

open access: yes
Animal sounds can be recognised automatically by machine learning, and this has an important role to play in biodiversity monitoring. Yet despite increasingly impressive capabilities, bioacoustic species classifiers still exhibit imbalanced performance across species and habitats, especially in complex soundscapes.

Age at Immigration and the Education Outcomes of Children [PDF]

open access: yes
The successful acquisition of a language is often characterized in terms of critical periods. If this is the case it is likely that children who migrate face different challenges in attaining high school credentials depending upon their age at ...

ARIONet: An Advanced Self-supervised Contrastive Representation Network for Birdsong Classification and Future Frame Prediction

open access: yes
Automated birdsong classification is essential for advancing ecological monitoring and biodiversity studies. Despite recent progress, existing methods often depend heavily on labeled data, use limited feature representations, and overlook temporal dynamics essential for accurate species identification.

Modeling and Confidence in a System for Automatic Classification of Birdsong

open access: yes, 2015
It turns out that using a two-state-HMM model structure with appurtenant GMM-based state distributions improves the system performance compared to the use of just GMMs as model structure for each bird specie. Hence, it is reasonable to say that birdsong contains temporary information which HMMs deals with in a better way than GMMs.
