论文《Deep Learning: A Bayesian Perspective》摘要:
Deep learning is a form of machine learning for nonlinear high dimensional
data reduction and prediction. A Bayesian probabilistic perspective provides a
number of advantages. Specifically statistical interpretation and properties,
more efficient algorithms for optimisation and hyper-parameter tuning, and an
explanation of predictive performance. Traditional high-dimensional statistical
techniques; principal component analysis (PCA), partial least squares (PLS),
reduced rank regression (RRR), projection pursuit regression (PPR) are shown to
be shallow learners. Their deep learning counterparts exploit multiple layers
of of data reduction which leads to performance gains. Stochastic gradient
descent (SGD) training and optimisation and Dropout (DO) provides model and
variable selection. Bayesian regularization is central to finding networks and
provides a framework for optimal bias-variance trade-off to achieve good out-of
sample performance. Constructing good Bayesian predictors in high dimensions is
discussed. To illustrate our methodology, we provide an analysis of first time
international bookings on Airbnb. Finally, we conclude with directions for
future research.
