Large-scale Machine Learning Systems Lab.

The Large-scale Machine Learning Systems Lab. (LMLS Lab) is a research group in the department of Computer Science and Engineering at Inha University, South Korea.

Our Mission

We study numerical optimization algorithms and systems for training machine learning models at scale across many heterogeneous machines and devices. Our work spans three connected threads: 1) distributed/federated learning, where we build optimizers that effectively utilize distributed data; 2) system-efficient deep learning, where we develop compute-, communication-, and memory-efficient learning methods that bridge the gap between theory and practice; 3) applied machine learning, where we study practical use-cases of various machine learning algorithms for scientific applications such as Physics.

We are always interested in hearing from self-motivated students and collaborators — see the People and Contact pages for more.
