To Interpolate or not to Interpolate: PRF, Dense and Sparse Retrievers [article]

Hang Li, Shuai Wang, Shengyao Zhuang, Ahmed Mourad, Xueguang Ma, Jimmy Lin, Guido Zuccon
2022 pre-print
In this paper we consider the problem of combining the relevance signals from sparse and dense retrievers in the context of Pseudo Relevance Feedback (PRF).  ...  The empirical findings from our experiments suggest that, regardless of sparse representation and dense retriever, interpolation both before and after PRF achieves the highest effectiveness across most  ...  Shuai Wang is supported by a UQ Earmarked PhD Scholarship and this research is funded by the Australian Research Council Discovery Projects program ARC DP210104043.  ...

Decision-support systems for establishing radiata pine plantations in the central North Island of New Zealand [article]

Euan G. Mason, University Of Canterbury
2012
Models of young radiata pine survival and size class distribution models were built for crops aged 0 to 5 years in the Central North island region of New Zealand.  ...  The basal area/ha function incorporated the allometric adjustment developed during the analysis of Nelder-design experiments in a way which resulted in compatible mean height and basal area/ha models.  ...  ACKNOWLEDGEMENTS The authors would like to thank Tasman Forestry Ltd. and the New Zealand Forest Research Institute which provided the datambase fOf, participated in,. and contributed financially to the  ...
