Deep learning for automatic image captioning in poor training conditions

Recent advancements in Deep Learning show that the combination of Convolutional Neural Networks and Recurrent Neural Networks enables the definition of very effective methods for the automatic captioning of images. Unfortunately, this straightforward result requires the existence of large-scale corpora and they are not available for many languages. This paper describes a simple methodology to automatically acquire a large-scale corpus of 600 thousand image/sentences pairs in Italian. At the best of our knowledge, this corpus has been used to train one of the first neural systems for the same language. The experimental evaluation over a subset of validated image/captions pairs suggests that results comparable with the English counterpart can be achieved
