Abstract:Methods that calculate dense vector representations for features in unstructured data - such as words in a document - have proven to be very successful for knowledge representation. Surprisingly, very little work has focused on methods for structured datasets where there is more than one type of feature - that is, datasets that have arbitrary features beyond words. We study how to estimate dense representations for multiple feature types within a dataset, where each feature type exists in a different higher-dimensional space. Feat2Vec is a novel method that calculates embeddings for data with multiple feature types enforcing that all different feature types exist in a common space. We demonstrate our work on two datasets, and our experiments suggest that Feat2Vec significantly outperforms existing algorithms that do not leverage the structure of the data.
TL;DR:Learn dense vector representations of arbitrary types of features in unlabeled datasets
