Then, images with equidistant embeddings are sampled. Since real-world datasets are often imbalanced leading to suboptimal models, the initial model is used to generate embeddings on the entire dataset. In step 1, a model capable of representing unlabeled images meaningfully is trained with a self-supervised algorithm (like SimCLR) on a random subset of the dataset (that conforms to researchers’ specified “training budget.”). The pipeline, purpose-built to take advantage of the massive amount of unlabeled images, consists of (1) self-supervision training to convert unlabeled images into meaningful representations, (2) search-by-example to collect a seed set of images, (3) human-in-the-loop active learning to iteratively ask for labels on uncertain examples and train on them.

We present a no-code open-source tool, Curator, whose goal is to minimize the amount of human manual image labeling needed to achieve a state of the art classifier.

While such images might exist in abundance within 40 petabytes of unlabeled satellite data, finding these positive examples to include in a training dataset for a machine learning model is extremely time-consuming and requires researchers to "hunt" for positive examples, like finding a needle in a haystack. For example, training classifiers for forest fires or oil spills from satellite imagery requires curating a massive and diverse dataset of example forest fires, a tedious multi-month effort requiring careful review of over 196.9 million square miles of data per day for 20 years. Machine learning modeling for Earth events at NASA is often limited by the availability of labeled examples.

To complete the package, AIDE offers both user annotation and model prediction evaluation, access control, customisable model training, and more, all through the web browser.ĪIDE is fully open source and available under. Furthermore, AIDE accepts any third-party model with minimal implementation requirements. All models can be customised and used without having to write a single line of code. 1: AIDE offers concurrent web image labelling support and uses annotations and deep learning models in an active learning loop.ĪIDE includes a comprehensive set of built-in models, such as ResNet for image classification, Faster R-CNN and RetinaNet for object detection, and U-Net for semantic segmentation. The result is a system where users only need to label what is required, which saves time and decreases errors due to fatigue.įig. In a second instance, it tightly integrates deep learning models into the annotation process through active learning, where models learn from user-provided labels and in turn select the most relevant images for review from the large pool of unlabelled ones (Fig. In a first instance, AIDE is a web-based annotation suite for image labelling with support for concurrent access and scalability, up to the cloud. In this abstract we present AIDE, the Annotation Interface for Data-driven Ecology. Machine learning, especially deep learning, could greatly accelerate this task through automated predictions, but involves expansive coding and expert knowledge.

For example, modern camera trap datasets contain millions of images that require prohibitive amounts of manual labour to be annotated with species, bounding boxes, and the like. Ecological research like wildlife censuses increasingly relies on data on the scale of Terabytes.
