  1. 1. Improving Aircraft Fuel Consumption Prediction through Ensemble Learning

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hanlin Gongzhang; [2022]
    Keywords : Aeronautics; Commercial Aircraft; Aircraft fuel consumption; Flight data; Aircraft performance model; Aircraft fuel consumption modelling; Weighted average ensemble; Machine learning; Flygteknik; Kommersiellt flyg; Flygplanens bränsleförbrukning; Flygdata; Flygplanens prestandamodell; Flygplans förbrukningsmodellering; Viktad medelvärdesensemble; Maskininlärning;

    Abstract : Performance models provided by aircraft manufacturers are used by aircraft operators to perform flight path simulations aiming to reduce aircraft fuel consumption. However, performance models are generic and does not account for the performance deviations of each aircraft individual. READ MORE

  3. 2. Boosting CNN Performance in Digital Pathology Using Colour Normalisation and Ensembling

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

    Author : Emelie Kvarnström; Axel Tibbling; [2021]
    Keywords : Colour normalisation; Histogram; Khan; Macenko; Reinhard; ensemble; digital pathology; histopathology; deep learning; EfficientNet;

    Abstract : Researchers within digital pathology are endeavouringto develop machine-learning tools to support dentists whenmaking a diagnosis. The purpose of this study was to investigatehow applying colour normalisation (CN) algorithms on an oral,histopathological dataset would impact both machine-learningmodels and ensembles of models when classifying cell types.

  4. 3. Anomaly Detection and Revenue Loss Estimation in Accounting Data

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

    Author : Gustav Edholm; [2020]
    Keywords : Machine Learning; Anomaly Detection; Regression; Neural Network; Invoice; Revenue Loss; Maskininlärning; Avvikelsedetektion; Regression; Neuralnät; Faktura; Omsättningsförlust;

    Abstract : Loss of revenue due to erroneous invoicing is a serious problem for many companies in the repair and maintenance industry. Revenue loss can occur in many ways, for example by consistently charging the wrong hourly price for services. READ MORE

  5. 4. Multi-factor Authentication : System proposal and analysis of continuous authentication methods

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Markus Fält; [2020]
    Keywords : continuous authentication; machine learning;

    Abstract :  It is common knowledge that the average user has multiple online accounts which all require a password. Some studies have shown that the number password for the average user is around 25. Considering this, one can see that it is unreasonable to expect the average user to have 25 truly unique passwords.

  6. 5. AUTOMATED OPTIMAL FORECASTING OF UNIVARIATE MONITORING PROCESSES : Employing a novel optimal forecast methodology to define four classes of forecast approaches and testing them on real-life monitoring processes

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Stanislav Razroev; [2019]
    Keywords : predictions; forecasting; optimal forecasting; forecast classes; optimality rules; ensemble forecasting; state switching; combinational forecasting; optimality framework; exponential smoothing; ARIMA; ARMA; SARIMA; Double-Seasonal Holt-Winters; time series; Wikipedia; Wikimedia; Wikipedia data; Twitter; Twitter data; electricity data; monitoring processes; monitoring process; monitoring; error metrics; outliers; missing values;

    Abstract : This work aims to explore practical one-step-ahead forecasting of structurally changing data, an unstable behaviour, that real-life data connected to human activity often exhibit. This setting can be characterized as monitoring process. READ MORE
