Summary and conclusions

3. Requirements & Scientific problem
Speech recognition requirements:
Sufficient storage space for large audio and text datasets
High Performance Computing (HPC):
Many CPUs as most training and recognition is performed in parallel
GPUs - use GPUs to train Deep neural nets (DNNs)
High speed internet to move data around compute nodes
Mechanism to manage datasets

4. Requirements & Scientific problem
Lack of collaboration
Lack of exploitation of the available distributed computing
Long hours of training systems on personal computers
Research questions to be answered :
Are speech recognition models reproducible ?
How do speech recognition models vary according to different dictionaries and training ?
Corollary issues :
Provenance and publication of models
ease of exploring ASR models – access for researchers
Make access to national language resources easier

5. Work done during the Hackfest
Website developed (90% finished):- (Jekyll )- display a few pages
Application ported to CODE-RADE
WebApp architecture completed and development commenced (Rails using MVC)
gLibrary installed
Access to FutureGateway test server obtained
Access to OAR obtained

6. WebApp architecture and designed to completion
Results
Website developed
WebApp architecture and designed to completion
Test case of the application successfully executed locally

7. Configure authentication and authorization Data ingestion into OAR
Future plans (until end of July and until the Workshop in Dar es Salaam on 5th of September - duplicate this slides as many time as needed)
End of July
Configure authentication and authorization
Data ingestion into OAR
Complete the Website
Test the job submission workflow
Workshop in Dar es Salaam (5 September)
WebApp complete
Use case complete
Test cases ran
Results obtained
Authoring of paper on the use case in progress

8. Summary and conclusions (tell us your experience about the Hackfest)
Excellent initiative in building capacity and bridging the digital divide
Educational and practically oriented (learnt a lot)
Good exposure and a platform to network with other researchers
The support was good
Organizers were ever present to assist
Gratitude goes out to:
Simon, Roberto, Bruce and the rest of the organizers and EU
The (geeks): Marco, Mario, Riccardo
The administration
Everyone else who contributed but I did not mention
Lastly to my University for assisting in making this possible
Sicily was great! The food awesome! Thank you guys.
