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!

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!

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

Th-th-th-that’s all folks!
