Add a topic feature to learning to rank model

2016

Latent Dirichlet Allocation (LDA), is heavily cited in the machine learning literature, but its feasibility and effectiveness in information retrieval is mostly unknown. Learning to rank is useful for document retrieval, it uses feature vector …

GHZ state, spin squeezed state, and spin coherent state for frequency estimation under general Gaussian noises

2024 · Communications in Theoretical Physics

Abstract Exploring the quantum advantages of various non-classical quantum states in noisy environments is a central subject in quantum sensing. Here we provide a complete picture for the frequency estimation precision of three important states …
