    :link: **Github:** [https://github.com/lydianish/RoLASER](https://github.com/lydianish/RoLASER)

    This demo app computes text embeddings of sentence pairs using the LASER encoder and its robust students RoLASER and c-RoLASER. 
    The pairwise cosine distances between the sentences are then computed and displayed.
