The 2D positional encoding is an extention to 2D data, e.g., images. It is implemented as positionalencoding2d. You can find examples and visualization in thisnotebook. For reference and technical details, please refer to our publication: ...
这被称为位置编码 (positional encoding)。 本项目利用 PaddlePaddle 做一个2D版本的简单实验 (这个实验在 CVPR 2020 Tutorial 的视频中提到): 已有一张图片, 用一个神经网络拟合它:对于任意一个点的二维坐标 (x,y)(x,y)(x,y), 输出(预测)图片在 (x,y)(x,y)(x,y) 处的像素值 (r,g,b)(r,g,...
To address this issue, we propose a new framework named TMIL (Transformer-based Multiple Instance Learning Network with 2D positional encoding), which leverages multiple instance learning for weakly supervised classification of histopathological images. TMIL incorporates a 2D positional encoding module, ...

The study adopts a two-stage approach. First, the BERT model is pretrained on each types of position encoding and PE using SMILES representations. Second, the model is fine-tuned on various downstream tasks using both SMILES and DeepSMILES molecular representations. Furthermore, their performance ...
For each protease of interest, as supplied in a.txt file with one MEROPS identifier per line, we use its substrates in MEROPS to construct a PSSM (25) matrix encoding the protease sequence specificity motif. This is then used to score all identified cleavage sites and provide a summed log ...
