Model description

This model was empowered by fine-tuned version of Distilbert and trained on Amazon Review Dataset, comprising of computer-generated fake reviews and genuine Amazon reviews. The fake reviews were generated by GPT-2, an AI text algoritm.

This model was trained to detect computer-generated fake reviews which generated by AI text algorithm.
