Multimodal Markov Random Field for Image Reranking Based on Relevance Feedback Table 1 MAP, precision at 5 (P5), 10 (P10), and 20 (P20) documents obtained by different parameter settings of the proposed multimodal MRF (columns 6–9), compared to the performance one would obtain with relevance feedback alone (columns 2–5). Column 1 indicates the parameter settings for the corresponding row as follows: the first value is
, the number of relevance feedback images,
is the value of
for the visual energy function (i.e.,
), and
is the value of
for the textual energy function (i.e.,
).
