Text-to-Image Diffusion Model采用U-Net结构[14],如图6所示, Imagen在U-Net的基础上插入了一些注意力层,这样能更好地利用文本信息。 图6 Imagen主要模块及工作流程[15] Text embedding的信息以pooled embedding vector的形式提供给模型,实现方法如图7所示。 图7 Pooled embedding vector示意图[15] Super-Resoluti...
Therefore, our vector will have a size of 8. To represent document 1, we simply take the first row in our table [1, 1, 1, 0, 0, 0, 0, 0]. This vector helps in comparing documents. While this technique is helpful in some use cases it has some limitations such as: does not ...
注意“backpropagate through CLIP and VQGAN all the way back to latent vector z”这句,一镜到底,是不是很大胆。 到此,你可能已经发现哪里不对了,这个反向传播不调整任何网络参数,而是调整了输入!(或者说中间结果)。 再细看还会发现,不同于常规神经网络反向传播都发生在训练(优化)阶段,这个反向传播是发生在...

又可以利用其他一般性token的输出向量用以支持稀疏检索(Sparse Retrieval)与多向量检索(Multi-vector Retrieval) 三种检索功能的高度集成使得BGE-M3可以一站式服务不同的现实场景,如语义搜索、关键字搜索、重排序 同时,无需使用多个模型进行多个推理,BGE-M3一次推理就可以得到多个不同模式的输出,无需额外开销,并能高效...

Word Embedding Class Word Embeddings transform is a text featurizer which converts vectors of text tokens into sentence vectors using a pre-trained model. Note As WordEmbedding requires a column with text vector, e.g. <'This', 'is', 'good'>, users need to create an input column by:...
