上圖可以回答問題1,Time2vec的表現比直接使用時間的效果好。 問題2:Time2Vec可以在其他架構中使用並提高其效能嗎? 上圖可以回答問題2,Time2vec在不同的模型中,效果都比較好。 問題3:正弦函式能學到什麼? 從上圖可以觀察到,Time2Vec可以學習到一種週期性的規律,例如圖3 a)中紅點的間隔是7天。 問題4: 我...

In this paper, we take an orthogonal but complementary approach by providing a model-agnostic vector representation for time, called Time2Vec, that can be easily imported into many existing and future architectures and improve their performances. We show on a range of models and problems that ...
In particular, we develop a learnable vector representation (or embedding) for time as a vector representation can be easily combined with many models or architectures. We call this vector representation Time2Vec. To validate the effectiveness of Time2Vec, we conduct experiments on several (...

The study of one or few-shot object recognition has been of interest for some time. 早期关于few-shot learning的工作往往设计生成模型和复杂的迭代推理策略。随着基于判别性的深度学习方法在多数据多shot setting中获得成功。人们对这种深度学习方法推广到few-shot learning的兴趣大增。其中许多方法使用元学习或le...
(1)输入部分,time series的每个time step的features 相当于一个句子里的一个token的embedding,但是根据实际经验来看,如果每个timestep的features太少做self attention效果不好,这里作者提供的方法是直接用一个shared的linear层来做升维的操作,看了下源代码确实是这么设计的https://github.com/gzerveas/mvts_transformer...
Our tracker demonstrated competitive accuracy on all the datasets while maintaining a real-time tracking speed of 41 FPS on the edge AI device Nvidia AGX Xavier. The main contributions of this work are as follows: We transfer and improve a learnable feature matching module, which performs the ...
