Click-through data has proven to be a critical resource for improving search ranking quality. Though a large amount of click data can be easily collected by search engines, various …
Learning to rank with biased click data is a well-known challenge. A variety of methods has been explored to debias click data for learning to rank such as click models, result …
Existing unbiased learning-to-rank models use counterfactual inference, notably Inverse Propensity Scoring (IPS), to learn a ranking function from biased click data. They handle the …

Recently a number of algorithms under the theme of'unbiased learning-to-rank'have been proposed, which can reduce position bias, the major type of bias in click data, and train a …
Implicit feedback (eg, clicks, dwell times, etc.) is an abundant source of data in human- interactive systems. While implicit feedback has many advantages (eg, it is inexpensive to …
Modern search systems are based on dozens or even hundreds of ranking features. The dueling bandit gradient descent (DBGD) algorithm has been shown to effectively learn …
