Community Bonding Period: April 24 — May 14, 2018

I started with GSoC on 24 April. I made contact with my mentors. I came to know that my primary mentor is Huijian Lv, littleowen and Mark Turner. I am talking to them since then. They also created a slack team for this year’s GSoC projects.

CWRU HPC Accounts

All students under Red Hen Lab were given access to HPC cluster at CWRU. Prof. Mark Turner asked us some details and our RSA public keys. In one or two days, our accounts were ready. Initially, I faced some problems while making a login into HPC cluster (password problems 😉 ). But after some days, that problem also resolved.

It turns out that the RedCat cluster is going away at the end of this month. So we finally use the Rider cluster (rider.case.edu) instead.

Chinese Pipeline

To go to a particular day, issue “day” with the date or the number of days ago:

day 2018–02–04
day 4

To navigate between dates, use:

day + 5
day — 30

You can also use this in a loop, for instance:

module load ffmpeg
for DAY in {08..31} ; do day 2018–01-$DAY ; for FIL in *_CN_*.txt ; do echo $FIL ; grep ‘DUR|’ $FIL ; ffprobe ${FIL%.*}.mp4 ; done ; done

View all the files related to Chinese Pipeline:

Deep Speech

My GSoC project is an extension to Mozilla’s Deep Speech.

The first work in the future for me is to understand and run existing code in my system: Practice on DeepSpeech Project using TensorFlow.
Another work which should be accomplished is to download the training data from the server.

Conclusion

Now the bonding period is over, and coding has started. I am strictly following my timeline, as proposed by me during GSoC application period (given on my proposal). I will be talking about the first week very soon. The first week gets over on 21 May. Till then, happy coding and cheers.
