Abstract
To effectively infuse the thought of locality sensitivity, an easy and efficient pre-processing module is made to learn appropriate representation for data partition, along with a global consensus regularize is brought to mitigate the chance of over fitting. The aim of image tag completion would be to precisely recover the missing labels for the images. To allow nonlinearity and the computational efficiency simultaneously, we turn to a locality sensitive approach, using the assumption that although nonlinear globally, the model could be straight line in your area, which enables the use of straight line models when samples are limited to individual parts of the information space. The present completion methods are often founded on straight line assumptions; therefore, the acquired models are restricted because of their incapability to capture complex correlation patterns. Extensive empirical evaluations conducted on three datasets demonstrate the success and efficiency from the suggested method, where our method outperforms previous ones with a large margin. Meanwhile, low-rank matrix factorization is utilized as local models, in which the local geometry structures are preserved for that low-dimensional representation of both tags and samples. We advise a locality sensitive lowrank model for image tag completion, which approximates the worldwide nonlinear model with an accumulation of local straight-line models, through which complex correlation structures could be taken
