Fake news detection is an important task for in- creasing the reliability of information on internet since fake spreading fast social media and has a negative effect our society. In this paper, we present novel method detecting by fusing multi-modal features derived from textual visual data. Specifically, proposed scaled dot- product attention mechanism to capture relationship between text extracted pre-trained BERT model VGG-19 model. Experimental results showed that improved against...

Abstract Digital transformation (DX) is complex with many automated parts, underlying integrations and processes that need to fit all together. Tools support the management of DX activities are, therefore, crucial for every business. However, there are just a few such tools available these days can help businesses both effectively comprehensively, but none them was designed particularly small- medium-size enterprises (SMEs) Vietnam. In this study, we will conduct an overview recent studies...
