UCTransNet: Rethinking the Skip Connections in U-Net from a Channel-wise Perspective with Transformer

3 code implementations9 Sep 2021 Haonan Wang, Peng Cao, Jiaqi Wang, Osmar R. Zaiane

Specifically, the CTrans module is an alternate of the U-Net skip connections, which consists of a sub-module to conduct the multi-scale Channel Cross fusion with Transformer (named CCT) and a sub-module Channel-wise Cross-Attention (named CCA) to guide the fused multi-scale channel-wise information to effectively connect to the decoder features for eliminating the ambiguity.

Sentiment and Knowledge Based Algorithmic Trading with Deep Reinforcement Learning

no code implementations26 Jan 2020 Abhishek Nan, Anandh Perumal, Osmar R. Zaiane

Algorithmic trading, due to its inherent nature, is a difficult problem to tackle; there are too many variables involved in the real world which make it almost impossible to have reliable algorithms for automated stock trading.

Self-Attentional Models Application in Task-Oriented Dialogue Generation Systems

no code implementations RANLP 2019 Mansour Saffar Mehrjardi, Amine Trabelsi, Osmar R. Zaiane

Self-attentional models are a new paradigm for sequence modelling tasks which differ from common sequence modelling methods, such as recurrence-based and convolution-based sequence learning, in the way that their architecture is only based on the attention mechanism.
