  1. 1. COMPARATIVE ANALYSIS OF MACHINE LEARNING LOAD FORECASTING TECHNIQUES

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

    Författare :Humphry Takang Bate; [2023]
    Nyckelord :;

    Sammanfattning : Load forecasting plays a critical role in energy management, and power systems, enabling efficient resource allocation, improved grid stability, and effective energy planning and distribution. Without accurate very short term load forecasting, utility management companies face uncertain load patterns, unrealistic prices, and poor infrastructure planning. LÄS MER

  3. 2. A Bayesian Bee Colony Algorithm for Hyperparameter Tuning of Stochastic SNNs : A design, development, and proposal of a stochastic spiking neural network and associated tuner

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Oskar Falkeström; [2023]
    Nyckelord :edge computing; edge user allocation; constraint satisfaction problem; bin packing problem; spiking neural networks; SNN; stochastic spiking neural networks; neuromorphic computing; hyperparameter tuning; swarm intellience; artificial bee colony algorithm; tree-structured Parzen estimator; stochastic optimization; Bayesian optimization.;

    Sammanfattning : With the world experiencing a rapid increase in the number of cloud devices, continuing to ensure high-quality connections requires a reimagining of cloud. One proponent, edge computing, consists of many distributed and close-to-consumer edge servers that are hired by the service providers. LÄS MER

  4. 3. Harnessing AI for Suicidal Ideation Detection: Thoroughly Evaluating and Fine-Tuning Transformer Models to Identify Suicidal Ideation in Social Media Posts

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen; Lunds universitet/Statistiska institutionen

    Författare :Johannes Altnäs; Keshav Sompura; [2023]
    Nyckelord :suicidal ideation; transformers; mental health; BERT; social media; Business and Economics;

    Sammanfattning : This thesis explored the application of pre-trained transformer models in detecting suicidal ideation in social media posts. We leveraged social media data from platforms like Reddit and Twitter and applied a robust hyperparameter random search strategy to fine-tune and evaluate existing transformer models. LÄS MER

  5. 4. The effect of the hyperparameters of an RBF SVM on classifying pneumonia

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Rikaz Nismi; Alfred Hoflin; [2022]
    Nyckelord :;

    Sammanfattning : Pneumonia is a deadly disease if gone untreated. In order to treat it, first it has to be discovered, which can be done by examining patterns of chest X-ray images. This process can be done by human experts but there is also a desire to make it more efficient by utilizing machine learning. LÄS MER

  7. 5. Machine Learning Models for Estimating Temperatures of Electric Powertrains

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Dinan Li; [2022]
    Nyckelord :Powertrain; machine learning; temperature monitoring; neuron network; Drivlina; maskininlärning; temperaturövervakning; neuronnätverk;

    Sammanfattning : Towards a sustainable future, more and more powertrains are being electrified today, thus it is important to prevent unwanted failures and secure a reliable operation. Monitoring the internal temperatures of powertrains and keeping them under their thresholds is an important first step. LÄS MER
