Advancing Ocean Observation with an AI-driven Mobile Robotic Explorer
Saad, Aya; Stahl, Annette; Våge, Andreas; Davies, Emlyn John; Nordam, Tor; Aberle-Malzahn, Nicole; Ludvigsen, Martin; Johnsen, Geir; Sousa, João; Rajan, Kanna (Journal article; Peer reviewed, 2020)Rapid assessment and enhanced knowledge of plankton communities and their structure in the productive upper water column is of crucial importance to understand the impact of the changing climate on upper ocean processes. ... -
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 ... -
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 ... -
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, ...
