Applying active learning techniques in machine learning to minimize labeling effort
Haug, Martin Lund (Master thesis, 2021)De mest fremtredende maskinlæringsmetodene (ML) for klassifisering er avhengige av en enorm mengde annotert data for å utvikle og trene nevrale nettverk til å utføre klassifisering så nøyaktig som mulig. Med den komplekse ... -
Attention segmentation approaches for plankton images captured in-situ
Borgersen, Jonas Nagell (Master thesis, 2021)Plankton er svært viktig for marine økosystemer, og for å forstå hvordan klimaendringer påvirker liv i vann er det nyttig å få innblikk i hvordan plankton bestander påvirkes av et endret klima. Målet med denne oppgaven er ... -
CIRAL: a hybrid active learning framework for plankon taxa labeling
Haug, Martin Lund; Saad, Aya; Stahl, Annette (Journal article; Peer reviewed, 2021)With the complex structure of planktonic species and an immense amount of data captured from autonomous underwater vehicles (AUVs), a large burden is placed on the domain experts for plankton taxa labeling. At the same ... -
A combined informative and representative active learning approach for plankton taxa labeling
Haug, Martin Lund; Saad, Aya; Stahl, Annette (Peer reviewed; Journal article, 2021)With an ever-increasing amount of image data, the manual labeling process has become the bottleneck in many machine learning applications. Plankton taxa labeling is especially a challenge due to its complex nature, and the ... -
Few-Shot Open World Learner
Teigen, Andreas Langeland; Saad, Aya; Stahl, Annette; Mester, Rudolf (Peer reviewed; Journal article, 2021)Computer vision based recognition systems in dynamically changing environments require continuously updating datasets with novel detected categories while maintaining equally high performance on previously established ... -
Few-shot open world learning
Teigen, Andreas Langeland (Master thesis, 2020)Datasynsystemer blir i økende grad tatt i bruk ute i dagligdags- og feltarbeidsapplikasjoner. Denne overgangen fra kontrollerte lab-omgivelser til den vide verden byr derimot på flere nye problemer. I stedet for kun å møte ... -
Implications of single-stage deep learning networks in real-time zooplankton identification
Ansari, Sadaf; Desai, Dattesh V.; Saad, Aya; Stahl, Annette (Peer reviewed; Journal article, 2023)Zooplankton are key ecological components of the marine food web. Currently, laboratory-based methods of zooplankton identification are manual, time-consuming, prone to human error and require expert taxonomists. Therefore, ... -
MOG: a background extraction approach for data augmentation of time-series images in deep learning segmentation
Borgersen, Jonas Nagell; Saad, Aya; Stahl, Annette (Journal article; Peer reviewed, 2021)Image segmentation is one of the key components in systems performing computer vision recognition tasks. Various algorithms for image segmentation have been developed in the literature. Among them, more recently, deep ... -
Object detection and instance segmentation of planktonic organisms using Mask R-CNN for real-time in-situ image processing.
Bergum, Sondre A. (Master thesis, 2020)Denne oppgaven er en undersøkelse av nylig presenterte state-of-the-art metoder og nettverksarkitekturer for bildesegmentering[61, 38, 37, 78, 49] ved bruk av Facebook Artificial Intelligence Research (FAIR) sitt software ... -
RAMARL: Robustness Analysis with Multi-Agent Reinforcement Learning - Robust Reasoning in Autonomous Cyber-Physical Systems
Saad, Aya; Håkansson, Anne (Peer reviewed; Journal article, 2022)A key driver to offering smart services is an infrastructure of Cyber-Physical systems (CPS)s. By definition, CPSs are intertwined physical and computational components that integrate physical behaviour with computation. ... -
Robust Deep Unsupervised Learning Framework to Discover Unseen Plankton Species
Salvesen, Eivind; Saad, Aya; Stahl, Annette (Journal article; Peer reviewed, 2021)Deep convolutional neural networks have proven effective in computer vision, especially in the task of image classification. Nevertheless, the success is limited to supervised learning approaches, requiring extensive amounts ... -
Robust Reasoning for Autonomous Cyber-Physical Systems in Dynamic Environments
Håkansson, Anne; Saad, Aya; Sadanandan Anand, Akhil; Gjærum, Vilde Benoni; Robinson, Haakon; Seel, Katrine (Peer reviewed; Journal article, 2021)Autonomous cyber-physical systems, CPS, in dynamic environments must work impeccably. The cyber-physical systems must handle tasks consistently and trustworthily, i.e., with a robust behavior. Robust systems, in general, ... -
Safe Learning for Control using Control Lyapunov Functions and Control Barrier Functions: A Review
Sadanandan Anand, Akhil; Seel, Katrine; Gjærum, Vilde Benoni; Håkansson, Anne; Robinson, Haakon; Saad, Aya (Peer reviewed; Journal article, 2021)Real-world autonomous systems are often controlled using conventional model-based control methods. But if accurate models of a system are not available, these methods may be unsuitable. For many safety-critical systems, ... -
Towards a balanced-labeled-dataset of planktons for a better in-situ taxa identification
Kiese, Oda Scheen (Master thesis, 2020)A studere mangfold og spredning av planktonorganismer in-situ er en pådriver for nyere forskningsaktiviteter og oseanografi på grunn av planktons økologiske betydning. Med introduksjonen av marine roboter utstyrt med ... -
