Noise Contrastive Estimation and Negative Sampling for Conditional Models: Consistency and Statistical Efficiency

2018

Noise Contrastive Estimation (NCE) is a powerful parameter estimation method for loglinear models, which avoids calculation of the partition function or its derivatives at each training step, a computationally demanding step in many cases. It …

Noncyclic nonadiabatic geometric quantum gates in a superconducting circuit

2023 · Physical Review Applied

Quantum gates based on geometric phases possess intrinsic noise-resilience features and attract much attention. However, the implementations of previous geometric quantum computation typically require a long pulse time of gates. As a result, their experimental …
