#4 CMU Sphinx

Hello guys!

We are getting close to the end of the summer, and I am almost done with my work for CMU Sphinx.


Since I last wrote here my main activity implied:

- memory optimizations;

- testing the code;

- preparing the code for integration;


My code has already been integrated and now I am working on the finishing touches.


Thank you for a great summer!

#3 CMU Sphinx

Hello all!

Time is passing and we are closer and closer to the end of the “Summer of code”.

Here is my progress since I previously posted:

- I implemented a module the clusters the gaussians from a mean file into a given number of classes. The clustering is made considering the euclidean distance between them. The purpose of clustering is to optimize adaptation process.

- I also implemented a module that adapts the acoustic model using the clustering tool that I’ve just described. The main idea of this type of adapting is the following: for each class(cluster) we collect counts separately and generate a separate transform. This way a more particular transform is estimated for each gaussian.

You can see my work at:

- https://github.com/bogdanpetcu/sphinx4/tree/master/sphinx4-core/src/main/java/edu/cmu/sphinx/decoder/adaptation        - adaptation package that I implemented from scratch.

- https://github.com/bogdanpetcu/sphinx4/tree/master/sphinx4-core/src/main/java/edu/cmu/sphinx/decoder/adaptation/clustered        - clustered adaptation package that I implemented from scratch.

- https://github.com/bogdanpetcu/sphinx4/commits/master        - here you can see all of my commits


Enjoy the rest of your summer!

Wyliodrin #2

Hello again!

Since my last post I took a short holiday and detached a little bit from work. So now I am buckling down to go the extra mile.

I have completed the PWM and Analog I/O functions. Now I am working on the I2C and SPI communication. The next step after the serial communication is to extend the same functions for other programming languages. I am very satisfied with my progress so far :D

Th-th-th-that’s all folks!


#1 Vmchecker

VMChecker will have a new look based on Meteor.js

So far I reimplemented the vmchecker interface to the point of the last interface and added the ability to download your last submission from server ( it needs polishing ).

Change Log:

  • Reimplemented Site using Meteor.js and Node.js
  • Elements of the site are now rearanged
  • Last Submision can now be downloaded
  • Solved Some Bugs
