   Sammanfattning : This thesis tackles the problem of predicting the collision risk for vehicles driving in complex traffic scenes for a few seconds into the future. The method is based on previous research using dynamic Bayesian networks to represent the state of the system. LÄS MER

5. 4. Basal Metabolic Rate (BMR) estimation using Probabilistic Graphical Models

   Master-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Zara Jackson; [2019]
   Nyckelord :Basal Metabolic Rate; Resting Metabolic Rate; Dynamic Bayesian Networks; Temporal Models; Food Tracking; Calories; Obesity; Pymc3; Probabilistic Programming;

   Sammanfattning : Obesity is a growing problem globally. Currently 2.3 billion adults are overweight, and this number is rising. The most common method for weight loss is calorie counting, in which to lose weight a person should be in a calorie deficit. LÄS MER

7. 5. Face Verification and Open-Set Identification for Real-Time Video Applications

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Jakob Grundström; [2015]
   Nyckelord :computer vision; face verification; open-set identification; real-time video analysis; joint bayesian classifier; local binary pattern; convolutional neural network; fine-tuning; deep representations; Mathematics and Statistics;

   Sammanfattning : In this work we aim to develop a video-based face verification algorithm suitable for real-time use in an embedded environment with limited space and restricted computational resources. We investigate face verification based solutions to envisioned real-time video applications that require open-set face identification. LÄS MER
