Channel Estimation for DCO-OFDM Based VLC Systems in the Presence of Clipping Noise
(Institute of Electrical and Electronics Engineers Inc., 2020)
Visible Light Communication(VLC) has been considered as a potential access option for 6G wireless systems to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. In VLC system, illumination ...
Multimodal retrieval with contrastive pretraining
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this paper, we present multimodal data retrieval aided with contrastive pretraining. Our approach is to pretrain a contrastive network to assist in multimodal retrieval tasks. We work with multimodal data, which has ...
FEATURE SELECTION USING SELF ORGANIZING MAP ORIENTED EVOLUTIONARY APPROACH
(Institute of Electrical and Electronics Engineers Inc., 2021)
Hyperspectral images are the multidimensional matrices consisting of hundreds of spectral feature vectors. Thanks to these large number of features, the objects on the Earth having similar spectral characteristics can ...
