JCSE: Contrastive Learning of Japanese Sentence Embeddings and Its Applications

1 code implementation19 Jan 2023 Zihao Chen, Hisashi Handa, Kimiaki Shirahama

To overcome this, we propose a novel Japanese sentence representation framework, JCSE (derived from ``Contrastive learning of Sentence Embeddings for Japanese''), that creates training data by generating sentences and synthesizing them with sentences available in a target domain.

Segmentation of Weakly Visible Environmental Microorganism Images Using Pair-wise Deep Learning Features

no code implementations31 Aug 2022 Frank Kulwa, Chen Li, Marcin Grzegorzek, Md Mamunur Rahaman, Kimiaki Shirahama, Sergey Kosov

The use of PDLFs enables the network to focus more on the foreground (EMs) by concatenating the pairwise deep learning features of each image to different blocks of the base model SegNet.
