Task-Adaptive Pseudo Labeling for Transductive Meta-Learning

no code implementations21 Apr 2023 Sanghyuk Lee, SeungHyun Lee, Byung Cheol Song

As a result, the proposed method is able to deal with more examples in the adaptation process than inductive ones, which can result in better classification performance of the model.

FP8 versus INT8 for efficient deep learning inference

no code implementations31 Mar 2023 Mart van Baalen, Andrey Kuzmin, Suparna S Nair, Yuwei Ren, Eric Mahurin, Chirag Patel, Sundar Subramanian, Sanghyuk Lee, Markus Nagel, Joseph Soriaga, Tijmen Blankevoort

We theoretically show the difference between the INT and FP formats for neural networks and present a plethora of post-training quantization and quantization-aware-training results to show how this theory translates to practice.

Contextual Gradient Scaling for Few-Shot Learning

1 code implementation20 Oct 2021 Sanghyuk Lee, SeungHyun Lee, Byung Cheol Song

Experimental results show that CxGrad effectively encourages the backbone to learn task-specific knowledge in the inner-loop and improves the performance of MAML up to a significant margin in both same- and cross-domain few-shot classification.

Hierarchical Auxiliary Learning

no code implementations3 Jun 2019 Jaehoon Cha, Kyeong Soo Kim, Sanghyuk Lee

Conventional application of convolutional neural networks (CNNs) for image classification and recognition is based on the assumption that all target classes are equal(i. e., no hierarchy) and exclusive of one another (i. e., no overlap).

On the Transformation of Latent Space in Autoencoders

no code implementations24 Jan 2019 Jaehoon Cha, Kyeong Soo Kim, Sanghyuk Lee

Noting the importance of the latent variables in inference and learning, we propose a novel framework for autoencoders based on the homeomorphic transformation of latent variables, which could reduce the distance between vectors in the transformed space, while preserving the topological properties of the original space, and investigate the effect of the latent space transformation on learning generative models and denoising corrupted data.

XJTLUIndoorLoc: A New Fingerprinting Database for Indoor Localization and Trajectory Estimation Based on Wi-Fi RSS and Geomagnetic Field

no code implementations17 Oct 2018 Zhenghang Zhong, Zhe Tang, Xiangxing Li, Tiancheng Yuan, Yang Yang, Meng Wei, Yuanyuan Zhang, Renzhi Sheng, Naomi Grant, Chongfeng Ling, Xintao Huan, Kyeong Soo Kim, Sanghyuk Lee

In this paper, we present a new location fingerprinting database comprised of Wi-Fi received signal strength (RSS) and geomagnetic field intensity measured with multiple devices at a multi-floor building in Xi'an Jiatong-Liverpool University, Suzhou, China.

A Scalable Deep Neural Network Architecture for Multi-Building and Multi-Floor Indoor Localization Based on Wi-Fi Fingerprinting

2 code implementations6 Dec 2017 Kyeong Soo Kim, Sanghyuk Lee, Kaizhu Huang

Exploiting the hierarchical nature of the building/floor estimation and floor-level coordinates estimation of a location, we propose a new DNN architecture consisting of a stacked autoencoder for the reduction of feature space dimension and a feed-forward classifier for multi-label classification of building/floor/location, on which the multi-building and multi-floor indoor localization system based on Wi-Fi fingerprinting is built.
