Artificial intelligence (AI) solutions are quickly becoming a key part of our society, and data labeling plays a major role in their success. Data labeling, also called annotation, refers to adding tags or labels to data like images, text, or audio so AI systems can learn to recognize patterns and make accurate predictions.
High-quality data labeling leads to exceptional AI systems, similar to skilled teachers shaping outstanding students. Unfortunately, the reverse is also true. Any oversight or errors in data annotation and labeling can have a huge impact on resulting AI models, and it happens more often than you would think. In fact, research shows that 85% of AI projects don’t succeed, primarily because of issues with data quality.
If you’re looking to build an AI solution, high-quality data annotations are the secret ingredient for success. However, curating such annotations isn’t as straightforward as it sounds - and that’s where Objectways can step in to help. Objectways has been a trusted expert in data labeling for over five years. We’ve labelefeed over 100 million data points so far, helping businesses create better AI systems.
Data annotation is a vital step in developing an AI model. It involves using labels to convert raw data into information and context for AI systems. Without proper data labels, training an AI model is like giving a student practice test questions without any explanations for the answers. Data labeling is especially critical for supervised machine learning models, which depend on labeled data to learn. In contrast, unsupervised machine learning can work with unlabeled data, discovering patterns on its own.
An interesting application of this is AI in healthcare. Computer vision models can be used to find tumors or bone fractures by training them on well-labeled X-rays and MRI scans. For instance, doctors and annotators can label regions on scans that show abnormalities, like fractures or tumors, giving the computer vision model clear examples of what to identify. Over time, the computer vision model becomes capable of spotting these issues in new scans, and doctors can use the model to catch health concerns faster and improve patient outcomes.
No two students learn the same way, so you can’t teach them all with a one-size-fits-all approach. In the same way, how we annotate data changes depending on the type of application and the kind of data we’re working with. Let’s take a closer look at the different types of data annotation methods and how they are used.
Computer vision is a subfield of AI focused on analyzing visual inputs like images and videos. In computer vision, data annotation usually involves tagging images and videos and linking each tag to a specific object or category.
Rectangular boxes drawn around objects in images to identify and locate them. They are commonly used in object detection for e-commerce, self-driving cars, and robotics.
Precise outlines created for irregularly shaped objects in images. They are often used in agriculture for mapping crops or in environmental monitoring.
Lines or curves drawn to highlight paths or boundaries in images that are essential for lane detection in autonomous driving systems.
Smooth, curved annotations are used to map complex shapes, such as winding roads or natural boundaries, in topographical analysis.
Specific points on an object, like joints or key features, that are marked for tasks like pose estimation in sports analysis and motion tracking.
