Welcome to SPSL(Signal Processing Systems Laboratory) at the Department of Electrical and Computer Engineering in Seoul National University.  The main research area of SPSL covers efficient signal processing, machine learning, and speech recognition. SPSL is supervised by Prof. Wonyong Sungand the team members include six Ph.D. students and three master students. We have presented our research at top conferences in the area of machine learning.  See our publication results for more details.

SPSL research areas include  
- Optimization of deep learning algorithms for fast inference and low power consumption
    - Structured pruning of deep neural network
    - Quantization of deep neural network
    - Parallelization of recurrent neural networks
- Deep learning based  end to end speech recognition
- Low power SoC (Systems on Chip)
