  1. 1. Evaluation of text classification techniques for log file classification

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Per Olin; [2020]
    Keywords : Text classification; machine learning; NLP; natural language processing; log file; doc2vec; CNN; LSTM; LSTM-CNN;

    Abstract : System log files are filled with logged events, status codes, and other messages. By analyzing the log files, the systems current state can be determined, and find out if something during its execution went wrong. READ MORE

  4. 4. Classification of Clothing Attributes Across Domains

    University essay from Linköpings universitet/Datorseende

    Author : Denise Härnström; [2020]
    Keywords : domain adaptation; image classification; cnn; fashion; surveillance;

    Abstract : Classifying clothing attributes in surveillance images can be useful in the forensic field, making it easier to, for example, find suspects based on eyewitness accounts. Deep Neural Networks are often used successfully in image classification, but require a large amount of annotated data. READ MORE

  5. 5. An application of Bayesian Hidden Markov Models to explore traffic flow conditions in an urban area

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Lovisa Andersson; [2019]
    Keywords : Bayesian statistics; hidden states; Markov chain; traffic flow modeling; filtering; smoothing; most probable state sequence; MCMC; Hamiltonian Monte Carlo; No-U-Turn sampler;

    Abstract : This study employs Bayesian Hidden Markov Models as method to explore vehicle traffic flow conditions in an urban area in Stockholm, based on sensor data from separate road positions. Inter-arrival times are used as the observed sequences. READ MORE
