Hints:前面提到的某些特征在某些任务不好学,选择辅助任务为predicting features(NLP中主任务为情感预测,辅助任务为inputs是否包含积极或消极的词;主任务name error detection,辅助任务为句子中是否有name) Focusing attention:使模型注意到那些在任务中可...

Related task:常规思路(自动驾驶+路标识别;query classification+web search;坐标预测+物体识别;duration+frequency) Adversarial:在domain adaption,相关的任务可能无法获取,可以使用对抗任务作为negative task(最大化training error),比如辅助任务为预测输入的domain,则导致主任务模型学习的表征不能区分不同的domain。
To address this issue, this paper proposes a density logging curve reconstruction model that integrates the multi-head self-attention mechanism (MSA) with temporal convolutional networks (TCN) and bidirectional gated recurrent units (BiGRU). This model uses the distance correlation coefficient to ...
Multi-head attention 本文基于《dive into deep learning》-pytorch 代码参考 《dive into deep learning》-pytorch multi-head attention 基本信息 我们可以会希望注意力机制可以联合使用不同子空间的key,value,query的表示。因此,不是只用一个attention pooling,query、key、value可以被h个独立学到的线性映射转换。最后...
首先看上面一行,输入的就是所谓的“文本描述”,也是作为Query存在的,对它过了一层Word Embedding,本文使用的是Bert,随后过了一层Transformer,并用来做cross-Attention,因为这里提取到的特征本质上已经是语言的特征了,可以直接和物体做跨注意力了。 除此之外,作者还在后面用了一个Text Classfier,本质上其实就是两个FC...
