1. 1. Fog detection using an artificial neural network

   University essay from Lunds universitet/Matematisk statistik

   Author : Quanwei Li; Tiancheng Ma; [2023]
   Keywords : Machine Learning; Deep Learning; Image Analysis; Computer Vision; Mathematics and Statistics;

   Abstract : This project studies a method of image-based fog detection directly from a camera without using the transmissometer. Fog can be detected using transmissometers which could be a very costly approach. This thesis presents an image-based approach for fog detection using Artificial Neural networks. READ MORE

3. 2. The Extended Maximum Likelihood Estimation for Monotone Probability Mass Function with Application using Forensic Data

   University essay from Lunds universitet/Matematisk statistik

   Author : Tiancheng Ma; [2022]
   Keywords : Statistical Inference Statistics Maximum Likelihood Estimation Non-parametric Estimation; Mathematics and Statistics;

   Abstract : This paper presents solutions to the modelling of frequency data of species labels, but the data is incomplete in the sense that some rarely-occurring species labels give zero observed frequency. The data can be modelled by a monotone probability function with parameters to be estimated, and yet, due to the order constraints and the incomplete data, using conventional parameter estimation methods will cause trouble.
