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

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

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

    Sammanfattning : 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.

  3. 2. An Analysis of Data Compression Algorithms in the Context of Ultrasonic Bat Bioacoustics

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Max Anderson; Benjamin Anderson; [2022]
    Nyckelord :bioacoustics; data compression; bats; audio data; ultrasonic;

    Sammanfattning : Audio data compression seeks to reduce the size of sound files, making them easier to store and transfer, and is thus a highly valued tool for those working with large sets of audio data. For example, some biologists work with audio recordings of bats, which are well known for their frequent use of ultrasonic echolocation, and so these biologists can accrue massive amounts of high frequency audio data.

  4. 3. Plant-plant communication - possible mechanisms and benefits

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Maria Hedsén; [2019]
    Nyckelord :plant-plant communication; plant interactions by VOC; plant interactions by sound; photomorphogenesis; thigomorphogenesis; bioacoustics;

    Sammanfattning : Plants interact with their environment in many ways. They can emit and receive volatile organic compounds (VOC) and sound. They can reflect specific wavelengths of light and detect these light signals, reflected by other plants. They can also feel when they are touched and distinguish different types of touch. LÄS MER

  5. 4. Kan datorer höra fåglar?

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Andreas Movin; Jonathan Jilg; [2019]
    Nyckelord :Bioacoustics; Fast Fourier transform FFT ; Spectral analysis; Voice recognition; Sound recognition; Bird song; Human voice; Spectrogram; Matching algorithms; Bioakustik; Fast Fourier transform FFT ; Spektralanalys; Röstigenkänning; Ljudigenkänning; Fågelsång; Mänsklig röst; Spektrogram; Ihopparningsalgoritm;

    Sammanfattning : Ljudigenkänning möjliggörs genom spektralanalys, som beräknas av den snabba fouriertransformen (FFT), och har under senare år nått stora genombrott i samband med ökningen av datorprestanda och artificiell intelligens. Tekniken är nu allmänt förekommande, i synnerhet inom bioakustik för identifiering av djurarter, en viktig del av miljöövervakning. LÄS MER
