1. 1. Machine Learning Prediction of Enzymes’ Optimal Catalytic Temperatures

   University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

   Author : Camille Finlinson Porter; [2023-03-22]
   Keywords : enzyme; protein; amino acid; protein structure; optimal catalytic temperature;

   Abstract : Enzymes that have been genetically engineered to withstand high temperatures are used by industry to make products with less waste and pollution. Different features of protein structure affect the optimal catalytic temperature ("topt") at which enzymes catalyze reactions most efficiently. READ MORE

3. 2. Nowcasting U.S. inflation using mixed frequency real-time data

   University essay from Lunds universitet/Matematisk statistik

   Author : Gustaf Lundgren; Nils Wicktor; [2023]
   Keywords : Inflation; Machine Learning; Nowcasting; MIDAS; Almon distributed lag models; Real-Time data; Random Forest; XGBoost; Mathematics and Statistics;

   Abstract : Different models were developed with the aim of nowcasting inflation at a daily basis with high frequency variables, while using real-time data to avoid look ahead bias. Both popular machine learning models such as Random Forest and XGBoost, and more traditional models such as UMIDAS and Almon distributed lag models were used to make the nowcasts. READ MORE

   Keywords : machine learning; recursive neural networks; web information extraction;

   Abstract : The internet is a source of abundant information spread across different web pages. The identification and extraction of information from the internet has long been an active area of research for multiple purposes relating to both research and business intelligence. READ MORE

5. 4. Analyzing the effect of competition in the hospitality industry

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Andreas Stasinakis; [2020]
   Keywords : Machine Learning; Competition; Competitive Analysis; Regression; LASSO;

   Abstract : Maximizing hotel's revenue is a hard and complicated task. A lot of aspects have to be taken into consideration during this procedure. One major variable is the competitors. Identifying hotel's competitors and using their behavior could be a crucial advantage for maximizing hotel's revenue. READ MORE

6. 5. Comparison of existing ZOI estimation methods with different model specifications and data.

   University essay from Högskolan Dalarna/Mikrodataanalys

   Author : Shraddha Mukhopadhyay; [2020]
   Keywords : Zone of Influence; reindeer; pellet group count; logistic regression; segmented model; Hierarchical Likelihood; Adaptive Lasso; threshold; breakpoint;

   Abstract : With the increasing demand and interest in wind power worldwide, it is interesting to study the effects of running windfarms on the activity of reindeers and estimate the associated Zone of Influence (ZOI) relative to these disturbances. Through simulation, Hierarchical Likelihood (HL) and adaptive Lasso methods are used to estimate the ZOI of windfarms and catching the correct threshold at which the negative effect of the disturbances on the reindeer behaviour disappears.
