mslr_web

  • Description:

MSLR-WEB are two large-scale Learning-to-Rank datasets released by Microsoft Research. The first dataset (called "30k") contains 30,000 queries and the second dataset (called "10k") contains 10,000 queries. Each dataset consists of query-document pairs represented as feature vectors and corresponding relevance judgment labels.

You can specify whether to use the "10k" or "30k" version of the dataset, and a corresponding fold, as follows:

ds = tfds.load("mslr_web/30k_fold1")

If only mslr_web is specified, the mslr_web/10k_fold1 option is selected by default:

# This is the same as `tfds.load("mslr_web/10k_fold1")`
ds = tfds.load("mslr_web")
FeaturesDict({
    'float_features': Tensor(shape=(None, 136), dtype=tf.float64),
    'label': Tensor(shape=(None,), dtype=tf.float64),
})
