  1. 1. Vibration-Based Terrain Classification for an Autonomous Truck

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

    Author : Lucas Lovén; [2022]
    Keywords : Autonomous vehicles; machine learning; surface identification; obstacle identification; signal processing; time series classification; Autonoma fordon; maskininlärning; detektering av underlag; detektering av hinder; signalhantering; tidsserie klassifiering;

    Abstract : This thesis is focused on developing vibration based terrain classification for an autonomous mining truck. The goal is to classify between good and bad gravel roads as well as good and bad asphalt roads. Current literature within vibration based terrain classification has been focused to a great extent on smaller research vehicles. READ MORE

  3. 2. Imbalanced Predictions

    University essay from Lunds universitet/Statistiska institutionen

    Author : Stella Säfström; [2022]
    Keywords : Imbalanced data; cost-sensitive learning; SMOTE; random undersampling; Mathematics and Statistics;

    Abstract : The aim of the thesis is to evaluate solutions to the class imbalance problem using real world data sets with varying degrees of class imbalance. The analysis is limited to binary classification. Three large data sets relating to credit card fraud, vehicle insurance and heart disease are used for the analysis. READ MORE

  4. 3. Beat Tracking of Jazz Instruments : Performance of Beat Tracking Algorithms on Jazz Drums and Double-Bass

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

    Author : Oskar Svanström; Linnéa Gustafsson; [2022]
    Keywords : Music information retrieval MIR ; Beat tracking; Jazz; Single instrument recordings; Algorithm evaluation.;

    Abstract : Beat tracking is a common research area within music information retrieval (MIR). Jazz is a musical genre that is commonly rich in rhythmical complexity, which makes beat tracking challenging. The aim of this study is to analyze how well beat tracking algorithms detect the beats of jazz instruments. READ MORE

  5. 4. Abstractive Summarization of Podcast Transcriptions

    University essay from Uppsala universitet/Artificiell intelligens

    Author : Hannes Karlbom; [2021]
    Keywords : ;

    Abstract : In the rapidly growing medium of podcasts, as episodes are automatically transcribed the need for good natural language summarization models which can handle a variety of obstacles presented by the transcriptions and the format has increased. This thesis investigates the transformer-based sequence-to-sequence models, where an attention mechanism keeps track of which words in the context are most important to the next word prediction in the sequence.

  6. 5. A Comparative Review of SMOTE and ADASYN in Imbalanced Data Classification

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Jakob Brandt; Emil Lanzén; [2021]
    Keywords : Machine learning; supervised learning; classification; class imbalance; over-sampling; SMOTE; ADASYN; Sensitivity; F-measure; Matthews correlation coefficient;

    Abstract : In this thesis, the performance of two over-sampling techniques, SMOTE and ADASYN, is compared. The comparison is done on three imbalanced data sets using three different classification models and evaluation metrics, while varying the way the data is pre-processed. READ MORE
