Bayesian Optimization (BO) has shown significant success in tackling expensive low-dimensional black-box optimization problems. Many problems of interest are high-dimensional, and scaling BO to such settings remains an important challenge. In this paper, we consider generalized additive models which functions with overlapping subsets variables composed model a high-dimensional target function. ...

By rapid progress of network and storage technologies, a huge amount of electronic data such as Web pages and XML data [23] has been available on intra and internet. These electronic data are heterogeneous collection of ill-structured data that have no rigid structures, and often called semi-structured data [1]. Hence, there have been increasing demands for automatic methods for extracting usef...

Over the past few years, research on vision-and-language navigation (VLN) has made tremendous progress. Many previous works attempted to improve performance from different aspects like training strategy, data augmentation, pre-training, etc. This work focuses a rarely-explored aspect in VLN, namely trajectory organization and encoding during navigation. Most of existing state-of-the-art VLN mod...

The importance of shea tree to the people of south-western Nigeria cannot be over emphasized considering both the economic and environmental uses of the tree. However, efforts have not been made to propagate its production by the farmers as the shea tree still grows in the wild state. It would be worthwhile to investigate farmers’ perception of shea nut tree as an economic tree and their attitu...
