We show that Bayes’ rule provides an effective mechanism for creating document translation models that can be learned from only parallel sentences and monolingual documents a compelling benefit because parallel documents are not always available. In our formulation, the posterior probability of a candidate translation is the product of the unconditional (prior) probability of the candidate output document and the “reverse translation probability” of translating the candidate output back into the source language. Our proposed model uses a powerful autoregressive language model as the prior on target language documents, but it assumes that each sentence is translated independently from the target to the source language. Crucially, at test time, when a source document is observed, the document language model prior induces dependencies between the translations of the source sentences in the posterior. The model’s independence assumption not only enables efficient use of available data, but it additionally admits a practical left-to-right beam-search algorithm for carrying out inference. Experiments show that our model benefits from using cross-sentence context in the language model, and it outperforms existing document translation approaches.

In this paper, we propose a multi-modal search engine for interior design that combines visual and textual queries.The goal of our engine is to retrieve interior objects, e.g.furniture or wall clocks, that share visual and aesthetic similarities with the query.Our search engine allows the user to take a photo of a room and retrieve with a high recall a list of items identical or visually similar to those present in the photo.Additionally, it allows to return other items that aesthetically and stylistically fit well together.To achieve this goal, our system blends the results obtained using textual and visual modalities.Thanks to this blending strategy, we increase the average style similarity score of the retrieved items by 11%.Our work is implemented as a Web-based application and it is planned to be opened to the public.
