  3. 2. Decoding communication of non-human species - Unsupervised machine learning to infer syntactical and temporal patterns in fruit-bats vocalizations.

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Luigi Assom; [2023]
    Keywords : animal decision making; unsupervised machine learning; UMAP; autoencoders; classifiers; bioacoustics; combinatory syntax; animal communication;

    Abstract : Decoding non-human species communication offers a unique chance to explore alternative intelligence forms using machine learning. This master thesis focuses on discreteness and grammar, two of five linguistic areas machine learning can support, and tackles inferring syntax and temporal structures from bioacoustics data annotated with animal behavior.

  4. 3. Comparison of CNN and LSTM for classifying short musical samples

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tore Nylén; Victor Stenmark; [2023]
    Keywords : ;

    Abstract : Applying machine learning to music and audio data is becoming increasingly common. One such area of research is instrument classification, which is the task of identifying the instrument played in a given audio file. In this study, we compared two machine learning model types, LSTM and CNN, on the task of classifying ten different instruments. READ MORE

  5. 4. Automatic loose gravel condition detection using acoustic observations

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Gionian Kyros; Elias Myrén; [2022]
    Keywords : Sound Classification; Supervised Machine Learning; Gravel roads assessment; SVM; Random Forest; Ensemble of bagged trees; Sound feature extraction;

    Abstract : Evaluation of the road's condition and state is essential for its upkeep, especially when discussing gravel roads, for the following reasons, among other. When loose gravel is not adequately maintained, it can pose a hazard to drivers, who can lose control of their vehicle and cause accidents. READ MORE

  6. 5. Voice Feature Extraction Using Siamese Neural Networks for Detecting Impersonators

    University essay from Lunds universitet/Matematisk statistik

    Author : Marlon Almström; Thi Thu Hòa Trân; [2022]
    Keywords : deep learning; voice impersonation; audio feature extraction; siamese neural networks; Mathematics and Statistics;

    Abstract : Voice impersonation is a technique that has often been used by criminals whose goal is to avoid being identified while committing a crime. There are, however, other interesting cases where the police confronts a suspect with an incriminating recording, and the suspect would deny being the true speaker in that recording, and claim that it belonged to an expert impersonator.
