Abstract
Collecting data on a large scale is vital for the development of cutting-edge artificial intelligence (AI) technologies, especially those involving machine learning (ML) models, such as deep neural networks, which require training with relevant data. On one hand, the collection of real-world data, using devices such as cameras and microphones, would enable AI systems to better understand everyday life and ultimately behave or assist in a manner akin to human interaction. On the other hand, growing concerns about security and privacy make it increasingly difficult to collect such real-world data. As a result, the emergence of digital twins offers a promising direction for intelligent robots that employ deep learning models for tasks such as perception, planning, localization, and control.

This presentation will discuss a framework for data collection, training, and learning, utilizing the assistance of digital twins. This approach leverages a collection of AI models for self-navigating mobile robots. We will focus particularly on developing visual perception models that interpret the real world through a camera. These models play a pivotal role in a variety of AI-powered products and services, such as autonomous vehicles and smart cities. They are also a primary research focus at Elsa Lab. Visual perception models based on deep neural networks have achieved unprecedented accuracy in benchmark datasets. Implementing these models would enable edge AI systems to better perceive and understand their environments, and therefore acting more intelligently in the real world. However, they often experience drops in accuracy and lack sufficient effective real-world data samples. This can lead to unsatisfactory performance and safety concerns in practical deployments.

To address the aforementioned problems, we explore and incorporate the following key technologies into our framework: virtual-to-real transfer learning, foundation model-based domain adaptation, and the usage of mid- level representations. Virtual-to-real transfer learning enables ML models to train first in simulated environments and then migrate to real-world settings with ease. Foundation model-based domain adaptation facilitates this migration process, even under challenging scenarios where data collection in the real world involves labor-intensive manual preprocessing. Moreover, mid-level representations are employed to transmit various types of information from the perception module to the control module, forming the basis of modular frameworks in many learning-based systems. The primary scientific challenge of this research direction lies in integrating these elements into a unified solution, and improving the adaptation ability of AI models to real- world environments. We will present how these methodologies can be integrated with existing systems for intelligent perception, planning, localization, and control in deep learning-based intelligent robotics.
