In today's data-driven landscape, the importance of data-centric machine learning methodologies cannot be overstated where they prioritize the quality, diversity, and accessibility of data, recognizing that the performance and reliability of machine learning models heavily depend on the data they are trained on. By delving into this research direction, PhD candidates have the opportunity to innovate methods for data collection, preprocessing, and augmentation, ensuring the integrity and richness of datasets. Moreover, advancements in data-centric machine learning not only enhance model accuracy and robustness but also promote fairness, transparency, and accountability in decision-making systems.
For the remote sensing image analysis research, the significance of data-centric techniques is paramount since remote sensing data, often acquired through satellites or aerial platforms, presents unique challenges such as noise, atmospheric interference, and varying spatial and spectral resolutions. Data-centric remote sensing methodologies play a pivotal role in addressing these challenges by enabling the extraction of meaningful information from vast and complex datasets.
This PhD research focused on data-centric approaches in remote sensing image/data analysis and is targeted to lead to the development of advanced algorithms for image preprocessing, feature extraction, and minimal supervision, ultimately enhancing the accuracy and efficiency of environmental monitoring, disaster management, urban planning, and agricultural assessment. Furthermore, by harnessing the power of data-centric techniques, this PhD is able to unlock valuable insights from remote sensing data, facilitating informed decision-making processes for sustainable resource management and environmental conservation efforts on a global scale.
Objectives of this PhD are given below:
1. Investigate the latest data-centric methodologies in machine learning and their suitability for analysing remote sensing data.
2. Explore new methods for preparing remote sensing data to improve its quality and address issues like noise, labelling inaccuracies, and artefacts.
3. Create advanced algorithms for extracting features from remote sensing data, considering its distinct characteristics such as radar, multispectral, and hyperspectral imagery, as well as ground measurements, from a multimodal perspective.
4. Develop original learning approaches, like deep learning models and transfer learning techniques, tailored for environmental applications in earth observation.
5. Assess the effectiveness and reliability of the developed algorithms by conducting thorough experiments on diverse remote sensing datasets, covering a range of environmental conditions and types of water and land cover.
