Descriptor Distillation: a Teacher-Student-Regularized Framework for Learning Local Descriptors

no code implementations23 Sep 2022 Yuzhen Liu, Qiulei Dong

This teacher-student regularizer is to constrain the difference between the positive (also negative) pair similarity from the teacher model and that from the student model, and we theoretically prove that a more effective student model could be trained by minimizing a weighted combination of the triplet loss and this regularizer, than its teacher which is trained by minimizing the triplet loss singly.

Numerical Solution of Fredholm Integral Equations of the Second Kind using Neural Network Models

no code implementations29 Sep 2021 Yuzhen Liu, Lixin Shen

The coefficients of this linear combination are served as the weights between the hidden layer and the output layer of the neural network while the mean square error between the exact solution and the approximation solution at the training set as the cost function.

NCS4CVR: Neuron-Connection Sharing for Multi-Task Learning in Video Conversion Rate Prediction

no code implementations22 Aug 2020 Xuanji Xiao, Hua-Bin Chen, Yuzhen Liu, Xing Yao, Pei Liu, Chaosheng Fan, Nian Ji, Xirong Jiang

To address this sharing&conflict problem, we propose a novel multi-task CVR modeling scheme with neuron-connection level sharing named NCS4CVR, which can automatically and flexibly learn which neuron weights are shared or not shared without artificial experience.
