Logs are provided in the synthetic/logs
folder. The files in that folder are a result of running the following commands:

Language Modelling & Machine Translation
The toolkit and scripts for language modeling experiments can be found at IDSIA/lmtool-fwms.
For machine translation experiments, we ported the different attention functions implemented in the language modeling toolkit to the multi-head attention implementation in FAIRSEQ.
