  Compositional Zero-Shot Learning (CZSL) has emerged as an essential paradigm
in machine learning, aiming to overcome the constraints of traditional
zero-shot learning by incorporating compositional thinking into its
methodology. Conventional zero-shot learning has difficulty managing unfamiliar
combinations of seen and unseen classes because it depends on pre-defined class
embeddings. In contrast, Compositional Zero-Shot Learning uses the inherent
hierarchies and structural connections among classes, creating new class
representations by combining attributes, components, or other semantic
elements. In our paper, we propose a novel framework that for the first time
combines the Modern Hopfield Network with a Mixture of Experts (HOMOE) to
classify the compositions of previously unseen objects. Specifically, the
Modern Hopfield Network creates a memory that stores label prototypes and
identifies relevant labels for a given input image. Following this, the Mixture
of Expert models integrates the image with the fitting prototype to produce the
final composition classification. Our approach achieves SOTA performance on
several benchmarks, including MIT-States and UT-Zappos. We also examine how
each component contributes to improved generalization.
