Abstract: Multilingual translators are provided with a plurality of input languages, a plurality of output languages, and a plurality of translation directions each of which from one of the input languages to one of the output languages. Multilingual translators include an encoder for each of the input languages and a decoder for each of the output languages. Each of the encoders is trained or trainable to translate from its input language to an arbitrary intermediate representation shared by all the translation directions and, furthermore, has its own encoding parameters or weights that are independent from the other encoders. Each of the decoders is trained or trainable to translate from the arbitrary intermediate representation to its output language and, besides, has its own decoding parameters or weights that are independent from the other decoders. Methods, computing systems, and computers programs for training such multilingual translators are also provided.
