  1. 41. Transformer-based Model for Molecular Property Prediction with Self-Supervised Transfer Learning

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

    Author : Lyu Lin; [2020]
    Keywords : Self-supervised Pre-training; Transfer Learning; Molecular Property Prediction; Transformer;

    Abstract : Molecular property prediction has a vast range of applications in the chemical industry. A powerful molecular property prediction model can promote experiments and production processes. The idea behind this degree program lies in the use of transfer learning to predict molecular properties. The project is divided into two parts. READ MORE

  2. 42. Regularization Methods in Neural Networks

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Jacob Kasche; Fredrik Nordström; [2020]
    Keywords : Neural Networks; Overfitting; Regularization methods; MNIST; CIFAR-10;

    Abstract : Overfitting is a common problem in neural networks. This report uses a simple neural network to do simulations relevant for the field of image recognition. In this report, four common regularization methods for dealing with overfitting are evaluated. READ MORE

  3. 43. Neural Network Regularization for Generalized Heart Arrhythmia Classification

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Oliver Glandberger; Daniel Fredriksson; [2020]
    Keywords : Arrhythmia; Classification; Regularization; Scaleogram; TensorFlow; Arytmi; Klassificering; Regularisering; Spektrogram; TensorFlow;

    Abstract : Background: Arrhythmias are a collection of heart conditions that affect almost half of the world’s population and accounted for roughly 32.1% of all deaths in 2015. More importantly, early detection of arrhythmia through electrocardiogram analysis can prevent up to 90% of deaths. READ MORE

  4. 44. Pressure Effects in Orifice Cavitation Modeling

    University essay from Umeå universitet/Institutionen för fysik

    Author : Henrik Sjöholm; [2020]
    Keywords : Fluid mechanics; Cavitation; Orifice plates;

    Abstract : In this thesis computational models for cavitating flows around orifice plates has been studied and compared. The goal was to fit a model with experimental data and this was done with some success, although problems with numerical stability, long calculation times and geometry overfitting remain. READ MORE

  5. 45. Classification Tree Based Algorithms in Studying Predictors for Long-Term Unemployment in Early Adulthood : An Exploratory Analysis Combining Supervised Machine Learning and Administrative Register Data

    University essay from Linköpings universitet/Institutionen för ekonomisk och industriell utveckling; Linköpings universitet/Filosofiska fakulteten

    Author : Sanni Kuikka; [2020]
    Keywords : long-term unemployment; life course research; register data; cohort study; supervised machine learning; CART; random forest;

    Abstract : Unemployment at young age is a negative life event that has been found to have scarring effects for future life outcomes, especially when continuing long-term. Understanding precursors for long-term unemployment in early adulthood is important to be able to target policy interventions in critical junctures in the life course. READ MORE
