Translation using deep neural networks (part 1)

the task of translation is approached using deep neural networks, it presents unique challenges due to the nature of language. This article discusses the evolution of language modeling, particularly focusing on translation through deep learning techniques, specifically recurrent neural networks (RNNs) and the introduction of attention mechanisms. The author compares two seminal papers: one by Sutskever et al. (2014), which does not utilize attention, and another by Bahdanau et al. (2015), which does. Despite Sutskever et al. reporting better performance, Bahdanau's work is recognized for its influential introduction of attention, highlighting a paradox in the research community. The article also addresses the difficulties in translation, such as handling sequences of arbitrary lengths and the complexities of large vocabularies. It emphasizes that translation is not merely about word-for-word mapping but requires understanding context and syntax. The author notes that while early models struggled with longer sentences, advancements in attention mechanisms have improved performance. The article sets the stage for further exploration of modern language modeling techniques, particularly transformers, in subsequent discussions.
