Quantum NLP models struggle with SPSA hyperparameter tuning

A new arXiv paper explores hyperparameter tuning for Variational Quantum Natural Language Inference (VQ-NLI) models. The research investigates the effectiveness of Simultaneous Perturbation Stochastic Approximation (SPSA) compared to parameter-shift gradients. While AdamW-style SPSA showed some improvement, it still lagged behind parameter-shift baselines due to high variance in its gradient estimates, particularly for models with a larger number of parameters.
