Query: Distributed Flexible Nonlinear Tensor Factorization   Tensor factorization is a powerful tool to analyse multi-way data. Compared
with traditional multi-linear methods, nonlinear tensor factorization models
are capable of capturing more complex relationships in the data. However, they
are computationally expensive and may suffer severe learning bias in case of
extreme data sparsity. To overcome these limitations, in this paper we propose
a distributed, flexible nonlinear tensor factorization model. Our model can
effectively avoid the expensive computations and structural restrictions of the
Kronecker-product in existing TGP formulations, allowing an arbitrary subset of
tensorial entries to be selected to contribute to the training. At the same
time, we derive a tractable and tight variational evidence lower bound (ELBO)
that enables highly decoupled, parallel computations and high-quality
inference. Based on the new bound, we develop a distributed inference algorithm
in the MapReduce framework, which is key-value-free and can fully exploit the
memory cache mechanism in fast MapReduce systems such as SPARK. Experimental
results fully demonstrate the advantages of our method over several
state-of-the-art approaches, in terms of both predictive performance and
computational efficiency. Moreover, our approach shows a promising potential in
the application of Click-Through-Rate (CTR) prediction for online advertising.
