Tourism Category Classification on Image Sharing Services Through Estimation of Existence of Reliable Results
Naoki Saito, Takahiro Ogawa, Satoshi Asamizu, Miki Haseyama · 2018
A new tourism category classification method through estimation of existence of reliable classification results is presented in this paper. The proposed method obtains two kinds of classification results by applying a convolutional neural network to tourism images and applying a Fuzzy K-nearest neighbor algorithm to geotags attached to the tourism images. Then the proposed method estimates existence of reliable classification results in the above two results. If the reliable result is included, the result is selected as the final classification result. If any reliable result is not included, the final result is obtained by another approach based on a multiple annotator logistic regression model. Consequently, the proposed method enables accurate classification based on the new estimation scheme.
