Quality annotation is one of the most important activity to be able to perform accurate Machine Learning and yet, it is probably one of the most boring activity ever for an operator. At CortAIx Factory, our goal is to offer AI-related resources for both internal and external use. We aspire to transform the process of annotating signals (radar, sonar, situation awareness, etc.) into an engaging experience for everyone, while ensuring that we maintain the highest quality of annotations, to deliver superior supervised machine learning solutions.
