Research Topics


We mainly focus on developing deep learning algorithms to solve many problems in the computer vision field. Including general tasks in computer vision such as classification or detection, we also study applicable work like generative models (GAN and diffusion models), depth estimation, medical imaging, noisy data, semantic segmentation, etc. Besides, there are many research on the fundamental structure of neural networks such as network minimization and architecture search in our laboratory. Our various research topics can be categorized into three sections which are  Deep Learning Applications, Neural Network Architecture, and Learning Methods. 

 

Deep Learning Applications


Our research topics in application of deep learning are focused on generative models (GAN, diffusion models), multi-modal learning, autonomous driving (depth estimation, object tracking, multi-sensor recognition), and anomaly detection (manufacturing, medical imaging).

Generative Models


Research focuses on improving various generative models such as StyleGAN and diffusion models to enhance image quality and provide smooth control over source features

Occlusion Removal


Removing or reconstructing occluded regions in an image, where an occlusion occurs when one object blocks another object from view

Multi-modal learning


Learning from multiple sources of data, such as vision-language. Aims to combine information from different modalities to improve performance and enhance understanding of the underlying data

Object Detection


Discover objects with directional orientation in bird's eye view images such as those captured by Radar or Satellite imaging

Anomaly Detection


Identifying unusual data points that deviate significantly from the normal or expected behavior in a dataset. Or, detecting abnormality in manufacturing process or medical images

Depth Estimation


Predicting the distance of objects in an image or video from a camera. It involves creating a model that can estimate the depth of each pixel in an image or a set of images, based on information such as the geometry of the scene and the movement of the camera

 

Neural Network Architecture


Our research on neural network architectures aims to find the optimal structure for convolutional neural networks. Recent topics include vision transformer, designing new architectures, or new operations in the network, and automated architecture search.

Lightweight Architecture


Designing a CNN-Transformer hybrid architecture with efficient cross-attention mechanism for lightweight RGB monocular depth estimation

Vision Transformer


Improving monocular depth estimation using a hierarchical transformer encoder, and lightweight decoder with selective feature fusion

Network Architecture


Designing a new CNN architecture with gradually increasing feature dimension (PyramidNet)

Neural Architecture Search


Automated architecture search with deep learning

 

Learning Methods


We study various topics in learning methods to solve problems in data used for training, such as noisy labels or biases. We also aim to improve the utilization of neural networks in real life through trustworthy ML, domain adaptation, and continual learning.

Noisy Labeled Data


Utilizing negative ground truth for robustness to noisy-labeled data (Negative Learning)

Biased Data


Learning useful information while not learning biases included in the data

Trustworthy ML


Research on vulnerabilities that exist in current deep learning models or systems (e.g., adversarial attack, model inversion attack, gradient inversion attack)

Domain Adaptation


Overcome the difference between the data distribution in the source domain and target domain and improve the model's performance on the target domain

Incremental Learning


Training a neural network with new data while keeping information learned from original data
