Abstract

The invention provides a target detection method and device, and the method comprises the steps: adding a pseudo tag for label-free data, and dividing the pseudo tag into a high-quality pseudo tag and an uncertain pseudo tag; inputting the label-free data into the initial learning model to obtain a first predicted value; determining a first prediction label and a first prediction frame based on a first prediction value corresponding to the high-quality pseudo label, and determining a second prediction label and a second prediction frame based on a first prediction value corresponding to the uncertain pseudo label; inputting the label-free data into the initial management model to obtain a second prediction value, and determining a third prediction label and a third prediction frame based on the second prediction value corresponding to the uncertain pseudo label; and training the initial management model based on the first prediction label, the first prediction frame, the second prediction label, the second prediction frame, the third prediction label and the third prediction frame to obtain a target management model which is used for performing target detection on the to-be-detected data. Through the scheme of the invention, acquisition of a large amount of labeled data is avoided.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a target detection method and device. Background technique [0002] Machine learning is a way to realize artificial intelligence. It is a multi-field interdisciplinary subject, involving probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory and other disciplines. Machine learning is used to study how computers simulate or implement human learning behaviors to acquire new knowledge or skills, and reorganize existing knowledge structures to continuously improve their own performance. Machine learning pays more attention to algorithm design, enabling computers to automatically learn laws from data and use the laws to predict unknown data. Machine learning has been used in a wide range of applications, such as deep learning, data mining, computer vision, natural language processing, biometric recognition, search ...
