Bias–variance analysis in estimating true query model for information retrieval
作者：
Highlights：
• We study the retrieval effectiveness-stability tradeoff in query model estimation.
• This tradeoff is investigated through a novel angle, i.e., bias–variance tradeoff.
• We formulate the performance bias–variance and estimation bias–variance.
• We investigate various query estimation methods using bias–variance analysis.
• Experiments have been conducted to verify hypotheses on bias–variance analysis.
