9-th Open Robotics Seminar - 2023.03
Five researchers attended the 9-th Open Robotics Seminar, held at Robotis Inc., Seoul. There were 13 sessions for introducing ROS applications. Picture
30th Korean Conference on Semiconductors (KCS 2023)- 2023.02
Eight researchers attended KCS 2023, held at High-One Resort, Kangwon-do. There were interesting topics including Processing-In-Memory, Hardware Accelerators, etc. At free time, they enjoyed beautiful scenery and good sightseeing. Picture
Movements of our AI Servers - 2023.02
We have five servers for machine learning and semiconductor design. These servers will be moved to our department's specific server room. We are happy to avoid noisy sound and hot air from them.
Welcome to a New Member - 2023.02
Se-Jin Kwon, an undergraduate student, joined our EmPasLab. She has interest in digging the details and secrets of machine learning.
Successful submission to ICML 2023 - 2023.01
At this time, Prof. Kim and Jung-Woo Shin have submitted their BNN (binarized neural networks) works to ICML 2023. ICML is one of top-tier AI conferences. Let's cross finger.
Studies with student researchers - 2023.01
During this winter vacation, several ideas and noticeable subjects for artificial intelligence and machine learning will be researched by student researchers and Prof. Kim. Notably, visual transformer, reinforcement learning for handling robot arm, TinyML, RISC-V based Posit arithmetics, BNNs are being focused. Good Luck!!
Welcome to a New Member - 2022.12
Young-Wook Kwon, a master candidate, joined our EmPasLab. He has interest in developing new visual transformer and inventing ideas for TinyML.
New Funds from SK Hynix - 2021.12
From December 2022, new funds from SK Hynix (Dec. 2022~Nov. 2024) begin, where methods and user interface for building supervised data in wafer testing will be developed.
Successful submission to ICCAD TinyML Contest
At this time, advised students and Prof. Kim have submitted their TinyML works to ICCAD TinyML Contests. In a small embedded board, binarized neural networks can be implemented, which significantly reduces hardware costs in terms of latency and parameter storage. In this work, this team can fully understand practical implementation of TinyML and methods about how to debug TinyML results.
Studies with student researchers (titled as BNNs for sound)
At this time, Prof. Kim and other advised students have studied binarized neural networks (BNNs) from this summer. For 1-D data (e.g. sound), BNNs are a very realistic form to be implemented on lightweight MCUs. Besides, their low latency and low power consumption can extend the applicable area of neural networks.
