Diploma/Master’s Thesis: Speaker Recognition with deep neural networks

Short Description :

You will extend a powerful neural network to solve speaker recogntion tasks. Therefore you will extend the model to learn the time dynamics of the underlying data. The model will be able classify speech by using a sequence 2 sequence learning [1] approach. You will learn how to implement fast and reliable neural network models on a GPU and will get a broad knowledge of machine learning. If possible the outcome of your work will contribute to a machine learning paper. If your are interested in this fascinating field of science
simply drop me an email.

Your Tasks :

• extend a neural network model in python on the GPU using THEANO [2]
• analyze the implemented systems in terms of accuracy and performance
• contribute to scientific work in form of a paper

Your Outcome :

• learn to implement and simulate very fast Neural Networks on a GPU
• learn how to solve difficult object recognition tasks
• get a broad education in on applied machine learning

Your Profile :

• motivation and reliability are a prerequisite
• good knowledge in machine learning and neural networks (at least >2 machine learning courses)
• knowledge in python programming

Additional Information :

This thesis project is planned for a duration of 6 months starting immediately. As it is a valid
contribution to an ongoing research project at the SPSC, it is rewarded with 2640e (440e per
month) and a good chance for publications.
