Experimental results on both the LETOR 4.0 dataset and a real-world Web search ranking dataset have demonstrated the effectiveness of the proposed active learning approach. ...
In this paper, we propose a general active learning for ranking strategy called Variance Maximization (VM). ...

An examination of the learned CNNs reveals several properties. First, a richer set of feature maps is necessary for predicting the responses to natural scenes compared to white noise. ...
Third, the injection of latent noise sources in intermediate layers enables our model to capture the sub-Poisson spiking variability observed in retinal ganglion cells. ...
Acknowledgments The authors would like to thank Ben Poole and EJ Chichilnisky for helpful discussions related to this work. ...
