Cascaded Cross-Modal Transformer for Audio-Textual Classification

1 code implementation15 Jan 2024 Nicolae-Catalin Ristea, Andrei Anghel, Radu Tudor Ionescu

Subsequently, we combine language-specific Bidirectional Encoder Representations from Transformers (BERT) with Wav2Vec2. 0 audio features via a novel cascaded cross-modal transformer (CCMT).

Sea Ice Segmentation From SAR Data by Convolutional Transformer Networks

no code implementations13 Jun 2023 Nicolae-Catalin Ristea, Andrei Anghel, Mihai Datcu

Sea ice is a crucial component of the Earth's climate system and is highly sensitive to changes in temperature and atmospheric conditions.

Explainable, Physics Aware, Trustworthy AI Paradigm Shift for Synthetic Aperture Radar

no code implementations9 Jan 2023 Mihai Datcu, Zhongling Huang, Andrei Anghel, Juanping Zhao, Remus Cacoveanu

The recognition or understanding of the scenes observed with a SAR system requires a broader range of cues, beyond the spatial context.

Guided Unsupervised Learning by Subaperture Decomposition for Ocean SAR Image Retrieval

no code implementations29 Sep 2022 Nicolae-Cătălin Ristea, Andrei Anghel, Mihai Datcu, Bertrand Chapron

Spaceborne synthetic aperture radar (SAR) can provide accurate images of the ocean surface roughness day-or-night in nearly all weather conditions, being an unique asset for many geophysical applications.

Fully Convolutional Neural Networks for Automotive Radar Interference Mitigation

1 code implementation21 Jul 2020 Nicolae-Cătălin Ristea, Andrei Anghel, Radu Tudor Ionescu

Moreover, considering the lack of databases for this task, we release as open source a large scale data set that closely replicates real world automotive scenarios for single-interference cases, allowing others to objectively compare their future work in this domain.
