• Authors: Joseph Early, Ying-Jung Deweese, Christine Evers, Sarvapali Ramchurn
• Abstract summary: Land cover classification (LCC) is an important process in climate change mitigation and adaptation. Existing approaches that use machine learning with Earth observation data for LCC rely on fully-annotated and segmented datasets. We propose Scene-to-Patch models: an alternative LCC approach utilising Multiple Instance Learning (MIL) that requires only high-level scene labels.

• Abstract: Land cover classification (LCC), and monitoring how land use changes over time, is an important process in climate change mitigation and adaptation. Existing approaches that use machine learning with Earth observation data for LCC rely on fully-annotated and segmented datasets. Creating these datasets requires a large amount of effort, and a lack of suitable datasets has become an obstacle in scaling the use of LCC. In this study, we propose Scene-to-Patch models: an alternative LCC approach utilising Multiple Instance Learning (MIL) that requires only high-level scene labels. This enables much faster development of new datasets whilst still providing segmentation through patch-level predictions, ultimately increasing the accessibility of using LCC for different scenarios. On the DeepGlobe-LCC dataset, our approach outperforms non-MIL baselines on both scene- and patch-level prediction. This work provides the foundation for expanding the use of LCC in climate change mitigation methods for technology, government, and academia.

  We address the memory and constraints of edge devices in the Continual Learning for Object Detection (CLOD) scenario. Specifically, we investigate the suitability of an open-source, lightweight, and fast detector, namely NanoDet, for CLOD on edge devices. We propose a novel CL method, called Latent Distillation(LD), that reduces the number of operations and the memory required by state-of-the-art CL approaches.

  Land use/land cover (LULC) maps play a pivotal role in supporting agricultural territory management, environmental monitoring and sustainable decision-making. New ground truth data must be collected, leading to the complete disregard of previously gathered reference data. We propose a deep learning framework to combine remote sensing and reference data coming from two different domains.

  We tackle the problem of cross-domain few-shot classification by making a small proportion of unlabeled images in the target domain accessible in the training stage. We meticulously design a cross-level knowledge distillation method, which can strengthen the ability of the model to extract more discriminative features in the target dataset. Our approach can surpass the previous state-of-the-art method, Dynamic-Distillation, by 5.44% on 1-shot and 1.37% on 5-shot classification tasks.

  Divide and Contrast (DaC) aims to connect the good ends of both worlds while bypassing their limitations. DaC divides the target data into source-like and target-specific samples, where either group of samples is treated with tailored goals. We further align the source-like domain with the target-specific samples using a memory bank-based Maximum Mean Discrepancy (MMD) loss to reduce the distribution mismatch.
