  3. 37. Automated Essay Scoring for English Using Different Neural Network Models for Text Classification

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Xindi Deng; [2021]
    Keywords : Automated Essay Scoring; neural network models; linguistic features;

    Abstract : Written skills are an essential evaluation criterion for a student’s creativity, knowledge, and intellect. Consequently, academic writing is a common part of university and college admissions applications, standardized tests, and classroom assessments. However, the task for teachers is quite daunting when it comes to essay scoring. READ MORE

  4. 38. Evaluating Unsupervised Methods for Out-of-Distribution Detection on Semantically Similar Image Data

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

    Author : Magnus Pierrau; [2021]
    Keywords : Out-of-distribution detection; anomaly detection; semantic similarity; image data; comparative evaluation; synthetic image data; Out-of-distribution detektion; anomali detektion; semantisk likhet; bilddata; jämförande utvärdering; syntetisk bilddata;

    Abstract : Out-of-distribution detection considers methods used to detect data that deviates from the underlying data distribution used to train some machine learning model. This is an important topic, as artificial neural networks have previously been shown to be capable of producing arbitrarily confident predictions, even for anomalous samples that deviate from the training distribution.

  5. 39. Machine Learning to Detect Anomalies in the Welding Process to Support Additive Manufacturing

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Vinod Kumar Dasari; [2021]
    Keywords : Autoencoders; Defect detection; Anomaly detection; Additive manufacturing; Welding defect detection;

    Abstract : Additive Manufacturing (AM) is a fast-growing technology in manufacturing industries. Applications of AM are spread across a wide range of fields. The aerospace industry is one of the industries that use AM because of its ability to produce light-weighted components and design freedom. READ MORE

  6. 40. Unsupervised Lexical Semantic Change Detection with Context-Dependent Word Representations

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Huiling You; [2021]
    Keywords : ;

    Abstract : In this work, we explore the usefulness of contextualized embeddings from language models on lexical semantic change (LSC) detection. With diachronic corpora spanning two time periods, we construct word embeddings for a selected set of target words, aiming at detecting potential LSC of each target word across time. READ MORE
