Transfer learning (TL) has attracted much attention as a machine learning methodology for efficient adaptation to various real-world data using external knowledge. In this tutorial, we will first introduce problem settings of TL. For homogeneous settings in which source and target domains share the same input spaces but the data distribution differs, we explain TL methods, e.g., instance-based, parameter-based, and feature-based methods. Then, we explain extension of feature-based methods to heterogeneous settings in which source and target domains have different input spaces. For some typical methods, we will also show input and output examples.

Gesture recognition is a natural and device-free way of non-verbal communications. It has many use cases in different applications ranging from smart-homes to human-robot interactions. Different modalities can be used to realize a gesture-based interface from RGB cameras to LiDARs and Radars. Radars, specifically mmWave radars, are robust to different lighting and weather conditions, they have small form factor, and given the high frequency range, they can detect subtle movements. In this tutorial session, first, we will discuss the basic principles of mmWave Frequency-Modulated Continuous-Wave (FMCW) radars. Then, the data representation (Point Cloud) of the radar will be introduced and the challenges of processing this type of data will be discussed. Finally, using graph-based neural networks, we will train a model to recognize gestures by processing the point clouds generated by the radars. The in-person participants will have the opportunity to work with the radars that they will be provided to record real-world data and process them using the pipeline we will introduce during the tutorial.
