1. 16. Complementary Labels and Their Impact on Deep Learning of a Target Class : Evaluated on Object Detection in the Low Data Regime

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Simon Sirak; [2021]
   Keywords : Object Detection; Low Data Regime; Complementary Labels; Deep Learning; Objektdetektion; Låg dataregim; Komplementära etiketter; Djupinlärning;

   Abstract : In specialized object detection tasks and domains, it is sometimes only possible to collect and annotate a small amount of data for training and evaluation, which constrains training to a low data regime that can lead to poor generalization. In this thesis, the impact of annotations from additional classes, referred to as complementary labels, when learning a target class is studied as a potential approach to improve performance in the low data regime, for object detection.

3. 17. Increasing Retention in Insurtechs Through Churn Prediction

   University essay from Lunds universitet/Innovationsteknik

   Author : John Rapp Farnes; Oskar Christiansen; [2021]
   Keywords : Non-life insurance; Property and casualty insurance; Customer retention; Churn prediction; Predictive analytics; Classification; Machine learning; Mathematics and Statistics;

   Abstract : Over the last decades, the Swedish insurance industry has seen decreased entry barriers due to deregulation and emerging new technologies, which have the potential to disturb the stagnated and consolidated competitive landscape of the industry. Initiated by newcomers like American insurance startup Lemonade, and later Swedish Hedvig among others, there is an increased push toward digitalization, transparency, and automation in the industry.

4. 18. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Sofia Francois; [2021]
   Keywords : Per- and polyfluoroalkyl substances PFASs ; Total oxidisable precursor TOP assay; solidphase extraction SPE ; washing steps; PFAS precursor compounds.;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) are man-made fluorinated compounds that havebeen detected in humans, the environment, and wildlife. The strong C-F bonds contribute tothe high thermal stability of some PFASs and make them extremely resistant to degradationunder normal environmental conditions. READ MORE

5. 19. Training Machine Learning-based QSAR models with Conformal Prediction on Experimental Data from DNA-Encoded Chemical Libraries

   University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

   Author : Gökçe Geylan; [2021]
   Keywords : Machine Learning; DNA-Encoded Chemical Library; Support Vector Machine; Random Forest; Conformal Prediction; QSAR;

   Abstract : DNA-encoded chemical libraries (DEL) allows an exhaustive chemical space sampling with a large-scale data consisting of compounds produced through combinatorial synthesis. This novel technology was utilized in the early drug discovery stages for robust hit identification and lead optimization. READ MORE

6. 20. Identification of changes in biomarkers relevant for breast cancer biology occurring in a novel 3D-Biosilk model

   University essay from KTH/Proteinvetenskap

   Author : Emmy Ståhl; [2021]
   Keywords : 3D-Biosilk; breast cancer; 3D cell culture; recombinant spider silk; ZO-1; 3D-Biosilk; bröstcancer; 3D cellkultur; rekombinant spindeltråd; ZO-1;

   Abstract : Bröstcancer är den vanligaste formen av cancer som drabbar kvinnor. Det är en heterogen och komplex sjukdom som består av flera undergrupper, var och en med distinkt morfologi och kliniska implikationer [1]. För att modellera och studera cellbiologi, vävnadsmorfologi, molekylära mekanismer och läkemedels effekter används cellkulturer [2]. READ MORE
