Data labeling, also known as annotation, is the process of assigning labels or tags to raw data to make it meaningful and usable for machine learning algorithms. It involves manually or automatically adding descriptive annotations, classifications, or tags to data instances, such as images, text, audio, or video, to provide ground truth or reference for training supervised learning models. Data labeling helps create labeled datasets for tasks like object detection, sentiment analysis, speech recognition, and more, enabling machine learning algorithms to learn patterns and make accurate predictions.
Researchers used convolutional neural networks and Sentinel-2 satellite imagery to classify tree species in Austrian forests. By integrating mixed species classes and spatial autocorrelation analysis, they improved the accuracy and reliability of large-scale tree species mapping, despite challenges with mixed pixels.
Scholars utilized machine learning techniques to analyze instances of sexual harassment in Middle Eastern literature, employing lexicon-based sentiment analysis and deep learning architectures. The study identified physical and non-physical harassment occurrences, highlighting their prevalence in Anglophone novels set in the region.
Researchers propose Med-MLLM, a Medical Multimodal Large Language Model, as an AI decision-support tool for rare diseases and new pandemics, requiring minimal labeled data. The framework integrates contrastive learning for image-text pre-training and demonstrates superior performance in COVID-19 reporting, diagnosis, and prognosis tasks, even with only 1% labeled training data.
