1. 6. Optimization and Bayesian Modeling of Road Distance for Inventory of Potholes in Gävle Municipality

   Kandidat-uppsats, Stockholms universitet/Statistiska institutionen

   Författare :Timothy Rafael Lindblom; Oskar Tollin; [2022]
   Nyckelord :Traveling salesman problem; Bayesian inference; Simulated annealing; Nearest neighbour algorithm; Markov Chain Monte Carlo; MCMC; Potholes; Haversine formula; Metropolis-Hastings; Posterior predictive distribution; Handelsresande problemet; bayesiansk inferens; simulerad anlöpning; nearest neighbour algorithm; Markov Chain Monte Carlo; MCMC; potthål; storcirkelavstånd; Metropolis-Hastings; posterior predictive distribution;

   Sammanfattning : Time management and distance evaluation have long been a difficult task for workers and companies. This thesis studies 6712 pothole coordinates in Gävle municipality, and evaluates the minimal total road distance needed to visit each pothole once, and return to an initial pothole. LÄS MER

3. 7. Data mining on Data sets of Products

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Robin Klingfors; [2022]
   Nyckelord :;

   Sammanfattning : With the increase of available data, companies are looking for ways to use it to their advantages. One tool that has become a suitable for this task is Data mining, which is a good tool to process and analyze large amounts of data. With the use of data mining, specifically machine learning, one can recognize patterns and classify data. LÄS MER

4. 8. Image classification of pediatric pneumonia : A comparative study of supervised statistical learning techniques

   Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Jacob Rönnefall; Jakob Wendel; [2022]
   Nyckelord :Machine learning; Algorithm; Logistic regression; K-nearest-neighbor; Support vector machine; Neural network; Sensitivity; Specificity; ROC; Accuracy;

   Sammanfattning : A child dies of pneumonia every 39 seconds, and the process of preventing deaths caused by pneumonia has been considerably slower compared to other infectious diseases. Meanwhile, the traditional method of manually diagnosing patients has reached its ceiling on performance. LÄS MER

5. 9. Recommender system for IT security scanning service : Collaborative filtering in an error report scenario

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

   Författare :Jonas Thunberg; [2022]
   Nyckelord :Collaborative Filtering; Vulnerability Scanning; IT-Security; Recommender System;

   Sammanfattning : Recommender systems have become an integral part of the user interface of many web applications. Recommending items to buy, media to view or similar “next choice”-recommendations has proven to be a powerful tool to improve costumer experience and engagement. LÄS MER

7. 10. Comparison of Machine Learning Algorithms for Anomaly Detection in Train’s Real-Time Ethernet using an Intrusion Detection System

   Kandidat-uppsats,

   Författare :Trayi Chaganti; Tadi Rohith; [2022]
   Nyckelord :Anomaly detection; Computing methodologies; Machine learning; Real-time Ethernet; Supervised learning;

   Sammanfattning : Background: The train communication network is vulnerable to intrusion assaultsbecause of the openness of the ethernet communication protocol. Therefore, an intru-sion detection system must be incorporated into the train communication network. LÄS MER
