  1. 1. BERT Language Modelling on Network Log Data for Generalized Unsupervised Intrusion Detection

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

    Author : Fynn van Westen; [2022]
    Keywords : BERT; Language-Modelling; Cyber-Security; Intrusion-Detection; NLP; Anomaly-Detection; One-Class-Classification; BERT; språkmodellering; cybersäkerhet; intrångsdetektering; NLP; anomalidetektering; en-klass-klassificering;

    Abstract : Intrusion detection is the most prominent topic of modern computer network security. The potential attack surface is growing exponentially every year. To cope with the amounts of data which accrue, automated methods for detecting undesired network activity are the only feasible solution. READ MORE

  3. 2. Application of Deep-learning Method to Surface Anomaly Detection

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Jiahui Le; [2021]
    Keywords : Image processing; Deep learning; Mask R-CNN; Surface anomaly detection; Surface defect detection;

    Abstract : In traditional industrial manufacturing, due to the limitations of science and technology, manual inspection methods are still used to detect product surface defects. This method is slow and inefficient due to manual limitations and backward technology. READ MORE

  4. 3. Learning from 3D generated synthetic data for unsupervised anomaly detection

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Hampus Fröjdholm; [2021]
    Keywords : machine learning; synthetic data; anomaly detection; physically based rendering; maskininlärning; syntetisk data; anomalidetektion;

    Abstract : Modern machine learning methods, utilising neural networks, require a lot of training data. Data gathering and preparation has thus become a major bottleneck in the machine learning pipeline and researchers often use large public datasets to conduct their research (such as the ImageNet [1] or MNIST [2] datasets).

  5. 4. Unsupervised anomaly detection for structured data - Finding similarities between retail products

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Jonas Fockstedt; Ema Krcic; [2021]
    Keywords : relational data; similarity analysis; data analysis; SQL; NetworkX; graph theory; anomaly detection; unsupervised; retail products; real-world data; AWS; amazon web services; similarity learning; data statistics; data preprocessing; similarity analysis algorithm; data validation;

    Abstract : Data is one of the most contributing factors for modern business operations. Having bad data could therefore lead to tremendous losses, both financially and for customer experience. READ MORE

  6. 5. Image-based anomaly detection using β -Variational Autoencoder for surface vehicle collision avoidance

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Johan Ahlqvist; André Skoog; [2020]
    Keywords : Technology and Engineering;

    Abstract : Unmanned vehicles need robust systems to ensure the safety of the vehicle and its environment. Being able to find and avoid perilous situations is paramount to such a system. READ MORE
