The EMI Lab - TU Delft

The Efficient circuits & systems for Machine Intelligence (EMI) research lab focuses on designing energy-efficient digital AI hardware (ASIC & FPGA) for edge computing, emphasizing ultrahigh-speed communication, video/audio processing, robotics, and biomedical applications. 

We strongly believe that hardware-software co-design is the path to realizing the ultimate goal of intelligent edge solutions for complex real-world applications.

Neuromorphic Eye Tracking at BioCAS 2023

August 24, 2023

We are glad to announce that our paper "3ET: Efficient Event-based Eye Tracking using a Change-Based ConvLSTM Network" has been accepted at the 2023 IEEE BioCAS conference. The paper introduces the Efficient Event-based Eye Tracking (3ET) system that employs a novel temporally sparse change-based ConvLSTM architecture to effectively extract sparse spatio-temporal features from event camera input streams in eye-tracking applications. Our network achieved over 30% better accuracy than CNN-based models and reduced computational operations by 4.7X compared to standard ConvLSTM models on event-based pupil datasets. This marks the first step of the EMI lab in building energy-efficient neuromorphic vision systems for emerging AIOT applications.
