1. 1. Feature Selection for Microarray Data via Stochastic Approximation

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

   Author : Erik Rosvall; [2024-03-18]
   Keywords : feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

   Abstract : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. READ MORE

3. 2. Reconstructing point patterns from spatially aggregated data

   University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

   Author : Jens Michelsen; [2024-03-13]
   Keywords : lorem; ipsum; dolor; sit; amet; consectetur; adipisicing; elit; sed; do.;

   Abstract : In this thesis we explore the ability to reconstruct samples (point configurations) from a point process, based only on the information contained in spatially aggregated data, namely the number of points in the partitions of a larger region. The ability to reconstruct a point configuration, in such a way that it retains most of it’s statistical properties, could be useful in cases where one is faced with a mixed dataset; some regions containing the full point configuration data, while other regions only contain aggregated data, i.

4. 3. Weather Factors and E. coli Concentration in Barnviken, Malmö - A Linear Mixed Model Approach

   University essay from Lunds universitet/Statistiska institutionen

   Author : Elias Gullberg; [2024]
   Keywords : Linear Mixed Models; Mathematics and Statistics;

   Abstract : Barnviken in Malmö has persistently encountered challenges associated with elevated concentrations of Escherichia coli (E. coli) without a discernible source of contamination. READ MORE

5. 4. Investigation of Injury Predictors for Rat Neuro Trauma

   University essay from KTH/Medicinteknik och hälsosystem

   Author : Rosetta Maglio; [2024]
   Keywords : Finite element method; Rat brain traumatic brain injury; Rat brain finite element model; Strain; Strain rate; Product of strain and strain rate; Rotational direction; Rotational duration; Injury prediction; Finita elementmetoden; Råtthjärnans finita elementmodell; Belastning; Belastningshastighet; Produkten av belastning och belastningshastighet; Rotationsriktning; Rotationstid; Skadeförutsägelse;

   Abstract : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. READ MORE

6. 5. Data analysis for predictive maintenance and potential challenges associated with the technology integration of steel industry machines.

   University essay from Högskolan i Gävle/Elektronik

   Author : Pradip Nath; [2024]
   Keywords : Data Science; Data processing; Industrial Manufacturing; System Identification; Predictive maintenance; Conditional monitoring; Statistical Analysis; Signal processing; Hydraulic System; IoT; Sustainable Maintenance; Data vetenskap; Databehandling; Industriell tillverkning; System identifiering; Prediktivt underhåll; Tillståndsövervakning; Statistisk analys; Signal behandling;

   Abstract : The recharge is the focus of data analysis of the different situations with the integration of the system and development of the two-stage 2/2 proportional cartridge valve for the steel industry machine. Using the statistical analysis technique to visualize the valve signal data behavior identify the accuracy of the machine data and apply the statistical feature extracting model using classification and clustering algorithms of real-time data analysis for the manufacturing.
