Abstract

This thesis looks at how to recommend healthy bundles consisting of dinner recipes. The proposed approach to evaluate the healthiness of recipes is based on the proportions of ingredi- ents. Furthermore, a bundling algo- rithm from previous work is adjusted to include the developed health mea- sure along with a trained SVD model. Different versions of the algorithm is tested in an offline setting in order to evaluate which version performs best. The accuracy of the SVD model is also compared with a KNN algorithm to determine if KNN is a viable option to SVD. Due to the complexity of bundles in regards to presentation, a user study with 16 participants is also conducted. The user study tests three different lay- outs with the purpose of finding which is best perceived.
