In recent years, deep neural networks (DNNs) have become the de facto machine learning tool and have revolutionized a variety of fields such as natural language processing [DCLT18], image perception [KSH12,RBH+21],geometry processing [QSMG17,ZBL+20]and3Dvision[DBI18, GLW+21]. Despite their widespread use, little is known about their theoretical properties.

So from this viewpoint, the Schedule-Free updates can be seen as a version of momentum that has the same immediate effect, but with a greater delay foradding intheremainder ofthegradient.

Recent works proposed various linear self-attention mechanisms, scaling only asO(L)for serial computation. We conduct a thorough complexity analysis of Performers,aclass which includes most recent linear Transformer mechanisms.

In a setting with multiple buyers, a buyer's expected value for an experiment may
