3. 2. Remote Sensing Based Pre-Season Yellow Rust Early Warning in Oromia, Ethiopia

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Chinatsu Endo; [2021]
   Nyckelord :yellow rust; modeling; prediction; early warning; remote sensing; geography; geographical information systems; GIS; Agriculture and Food Sciences; Earth and Environmental Sciences;

   Sammanfattning : Yellow rust (Puccinia striiformis f. sp. Tritici) is a crop disease caused by a fungus that regularly infects wheat and causes yield loss in Ethiopia. The disease has a significant impact on the country’s crop production, food security, health, and socioeconomic well-being. LÄS MER

4. 3. Purchase Probability Prediction : Predicting likelihood of a new customer returning for a second purchase using machine learning methods

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

   Författare :Olivia Alstermark; Evangelina Stolt; [2021]
   Nyckelord :Purchase Probability Prediction; Machine Learning Models; Well-Calibrated Probabilities; Imbalanced Data; Data Protection;

   Sammanfattning : When a company evaluates a customer for being a potential prospect, one of the key questions to answer is whether the customer will generate profit in the long run. A possible step to answer this question is to predict the likelihood of the customer returning to the company again after the initial purchase. LÄS MER

5. 4. Venn Prediction for Survival Analysis : Experimenting with Survival Data and Venn Predictors

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

   Författare :Ignacio Aparicio Vázquez; [2020]
   Nyckelord :Venn Predictors; Random Forests; Survival Modelling; Machine Learning; Well Calibrated Probabilities; Out-of-bag Calibration; Anomaly Detection; Venn Predictors; Slumpmässiga Skogar; Survival Modelling; Machine Learning; Välkalibrerade sannolikheter; Out-of-bag Calibration; Anomalidetektion;

   Sammanfattning : The goal of this work is to expand the knowledge on the field of Venn Prediction employed with Survival Data. Standard Venn Predictors have been used with Random Forests and binary classification tasks. However, they have not been utilised to predict events with Survival Data nor in combination with Random Survival Forests. LÄS MER

7. 5. Transition Matrices Conditional on Macroeconomic Cycles: A Portfolio Stress-Test Application

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Jesper Karlsson; [2018-07-04]
   Nyckelord :Risk Management; Migration Analysis; Intensity Models; IFRS 9; Basel Accords; Portfolio Stress Test;

   Sammanfattning : Transition matrices show the probabilities of credit rating migrations for a pool of ratings within a particular industry, geographical area, time-horizon, etc. Regulation, in the form of Basel accords, has opted for standards in banking that among other techniques use transition matrices, and thus the probability of default, for internally-based risk-assessment, as well as incorporating the external credit rating in the capital requirement calculation.
