Task-aligned spectral inductive biases in parameterized quantum circuits
Provides theoretical insights for quantum machine learning researchers working on circuit architecture design and inductive biases.
AI Summary
Researchers demonstrate how task-aligned spectral queries in parameterized quantum circuits improve learning performance by modulating signal frequencies without adding new sample-dependent information.
Excerpt
Parameterized quantum circuits are widely investigated in quantum machine learning, yet how their architecture can provide task-aligned inductive biases remains poorly understood. We study data reuploading quantum circuits with two distinct inputs: a signal that varies between samples and a fixed, task-defined spectral query that specifies how the signal should be probed. We show that encoding the query can change the circuit's hypothesis class over the signal by modulating how its existing sign
