 ## Age and Gender Recognition Model
 
-TBD...
+The age and gender recognition model is a multitask network, which employs a feature extraction layer, an age regression layer and a gender classifier. The model has a size of roughly 420kb and the feature extractor employs a tinier but very similar architecture to Xception.
+
+This model has been trained and tested on the following databases with an 80/20 train/test split each: UTK, FGNET, Chalearn, Wiki, IMDB*, CACD*, MegaAge, MegaAge-Asian. The `*` indicates, that these databases have been algorithmically cleaned up, since the initial databases are very noisy.
+
+### Total Test Results
+
+Total MAE (Mean Age Error): **4.54**
+
+Total Gender Accuracy: **95%**
+
+### Test results for each database
+
+The `-` indicates, that there are no gender labels available for these databases.
