Researchers have introduced a new initialization technique called ternary grid initialization for trainable-frequency (TF) circuits in quantum machine learning (QML). This method addresses a gradient suppression issue that previously hindered TF circuits from effectively adapting their frequency spectrum during training. By setting prefactor values to powers of three, ternary initialization ensures that target frequencies are closely approximated from the start, enabling reliable convergence. Empirical results show a significant improvement in performance compared to standard unary initialization, with TF circuits achieving near-perfect accuracy on synthetic benchmarks and demonstrating consistent advantages on real-world datasets.
