Special Issue Information

Dear Colleagues,

Machine Learning has recently achieved significant accomplishments across a diverse array of application domains (e.g., computer vision). Nonetheless, these achievements are heavily contingent upon substantial reservoirs of data and computational resources. This dependence poses a challenge in most real-world scenarios where data and computation resources are scarce. Our goal is to confront this challenge by devising effective strategies for implementing machine learning under conditions of limited resources, encompassing data, models, and knowledge. Consequently, researchers across various fields have turned their attention to the exploration of efficient learning methodologies. These methodologies encompass three key dimensions:

  1. Efficient data processing algorithm, which involves techniques such as lossy or lossy coding.
  2. Efficient model processing algorithm, which practices such as channel pruning and neural architecture search to enhance computational efficiency.
  3. Efficient knowledge transferring algorithm, as exemplified by transfer learning techniques including knowledge distillation that leverage existing knowledge effectively.

We extend an invitation to experts not only from these specific domains but also from related fields to engage in collaborative efforts and put forth groundbreaking methodologies. We hold a particular interest in receiving proposals that compose multiple themes mentioned above. For instance, we strongly encourage the exploration of integrated approaches that merge data and machine efficiency, employing compressed networks to reduce data volume. We believe such innovative methodologies harbor the potential to reshape the trajectory of machine learning and its applications, spanning realms such as computer vision and natural language processing. By addressing the formidable challenges posed by resource limitations, we aspire to make substantial contributions to the broader research community.

Precision agriculture involves the application of advanced technologies to improve agricultural productivity, efficiency, and profitability while minimizing waste and environmental impacts. Deep learning approaches enable automated decision-making for many visual tasks. However, in the agricultural domain, variability in growth stages and environmental conditions, such as weather and lighting, presents significant challenges to developing deep-learning-based techniques that generalize across different conditions. The resource-intensive nature of creating extensive annotated datasets that capture these variabilities further hinders the widespread adoption of these approaches. To tackle these issues, we introduce a semi-self-supervised domain adaptation technique based on deep convolutional neural networks with a probabilistic diffusion process, requiring minimal manual data annotation. Using only three manually annotated images and a selection of video clips from wheat fields, we generated a large-scale computationally annotated dataset of image–mask pairs and a large dataset of unannotated images extracted from video frames. We developed a two-branch convolutional encoder–decoder model architecture that uses both synthesized image–mask pairs and unannotated images, enabling effective adaptation to real images. The proposed model achieved a Dice score of 80.7% on an internal test dataset and a Dice score of 64.8% on an external test set composed of images from five countries and spanning 18 domains, indicating its potential to develop generalizable solutions that could encourage the wider adoption of advanced technologies in agriculture.
