Distributional Reinforcement Learning with Ensembles
Björn Lindenberg, Jonas Nordqvist, Karl-Olof Lindahl
It is well known that ensemble methods often provide enhanced performance in reinforcement learning. In this paper, we explore this concept further by using group-aided training wi…
Wildly ramified power series with large multiplicity
Jonas Nordqvist
In this paper we consider wildly ramified power series, \emph{i.e.}, power series defined over a field of positive characteristic, fixing the origin, where it is tangent to the ide…
Residue fixed point index and wildly ramified power series
Jonas Nordqvist, Juan Rivera-Letelier
In this paper, we study power series having a fixed point of multiplier 1. First, we give a closed formula for the residue fixed point index, in terms of the first coefficients of…
On-the-fly Detection of Autogenerated Tweets
Jonas Lundberg, Jonas Nordqvist, Antonio Matosevic
Most previous work related to tweet classification have focused on identifying a given tweet as a spam, or to classify a Twitter user account as a spammer or a bot. In most cases t…
