The resulting agent outperforms RainbowonAtari, installing anewState oftheArtwith very little modifications to the original algorithm.

Conventional models prepare a large embedding matrix whose size depends on the vocabulary size. Therefore, storing these models in memory and disk storage is costly.

Manynon-parametric regression methods areproposed to solve the regression problem by assuming thatf falls into certain function classes, including polynomial splines Stone (1994), local polynomials Cleveland (1979); Stone (1977), the spectral algorithmsCaponnetto(2006);CaponnettoandDeVito(2007);CaponnettoandYao(2010),etc.

Recently,researchers extended 1-hop message passing to K-hop message passing by aggregating information fromK-hop neighbors of nodes simultaneously. However, there is no work on analyzing the expressive powerofK-hopmessagepassing.

In this paper, we study the problem of unsupervised object segmentation from single images.
