   Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Författare :Edvin Jakobsson; [2019]
   Nyckelord :Natural Language Processing Machine Learning Automated Essay Scoring; Technology and Engineering;

   Sammanfattning : The task of Automated Essay Scoring (AES) has been active for more than half a century, starting with handcrafting statistical features used for linear regression, and currently being improved by the latest advancements in machine learning and natural language processing. Most current research uses some form of character or word embeddings to represent the essays rather than statistical features, enabling the models to analyze the text in full and automatically learn what to look for.

3. 2. Applying the Maxout Model to Increase the Performance of the Multilayer Perceptron in Shallow Networks

   Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Författare :Edvin Jakobsson; [2016]
   Nyckelord :Maxout; Network; Multilayer perceptron; Artifical neural network; Physics and Astronomy;

   Sammanfattning : The Maxout network is an alternative to artificial neural networks that use fixed activation functions. By adding extra layers of linear nodes the Maxout network is able to learn both the relationship between the hidden nodes and the activation function that they use. LÄS MER
