Deep Learning

<The core of next-gen machine learning technology for challenging the human brain>
NAVER LABS researches and applies a state of the art deep learning techniques
competitive to other global companies. Deep learning has already been applied to NAVER's app voice recognition, automatic image classification in Knowledge iN and NDrive, resulting to outstanding quality enhancement.
We plan to expand our landscape to advanced cognitive technology, which will enable machine translation
based on human language modeling, emotion analysis, document summary, word meaning comprehension, natural language process, and more.
