Resumo: | |||||||||||||
Deep learning techniques have shown significant contributions in various
fields, including image analysis. The vast majority of work in computer
vision focuses on proposing and applying new machine learning models
and algorithms. For supervised learning tasks, the performance of these
techniques depends on a large amount of training data and labeled data.
However, labeling is an expensive and time-consuming process.
A recent area of exploration is the reduction of efforts in data preparation,
leaving it without inconsistencies and noise so that current models can
obtain greater performance. This new field of study is called Data-Centric
AI. We present a new approach based on Deep Reinforcement Learning
(DRL), whose work is focused on preparing a dataset, in object detection
problems where the bounding box annotations are done autonomously and
economically. Our approach consists of creating a methodology for training
a virtual agent in order to automatically label the data, using human
assistance as a teacher of this agent.
We implemented the Deep Q-Network algorithm to create the virtual agent
and developed a counseling approach to facilitate the communication of the
human teacher with the virtual agent student. We used the active learning
method to select cases where the agent has more significant uncertainty,
requiring human intervention in the annotation process during training to
complete our implementation. Our approach was evaluated and compared
with other reinforcement learning methods and human-computer interaction
in different datasets, where the virtual agent had to create new annotations
in the form of bounding boxes. The results show that the use of our
methodology has a positive impact on obtaining new annotations from
a dataset with scarce labels, surpassing existing methods. In this way,
we present the contribution in the field of Data-Centric AI, with the
development of a teaching methodology to create an autonomous approach
with human advice to create economic annotations from scarce annotations.
