Cover Story: Efficient and scalable vision models are vital for real-world applications like medical imaging and deepfake detection. MobileNet-HeX introduces a novel framework leveraging Heterogeneous MobileNet eXperts to deliver top-tier performance with low computational demands. The Expand-and-Squeeze mechanism ensures diversity in a MobileNet population, selecting high-performing, heterogeneous models through clustering. These models are then combined using Sequential Quadratic Programming to form an optimized ensemble. MobileNet-HeX surpasses state-of-the-art vision models in accuracy, speed, and memory efficiency on tasks such as skin cancer classification and deepfake detection, demonstrating the power of lightweight, heterogeneous ensembles.
