Privacy-Preserving Age Estimation for Content Rating.

Abstract
Content rating (aka. maturity rating) rates the suitability of kinds of media (e.g., movies and video games) to its audience. It is essential to prevent a specific age group of people such as children from inappropriate information. However, in practice the administration of content rating system is usually suggestion-based declaration by media sources or key-based password which can easily fail if someone ignores the suggestions or somehow knows the keys. In this paper, we propose to estimate user's age in a privacy-preserving manner for automatic content rating. Several privacy-preserving approaches on facial images with different degree of privacy are proposed and evaluated on a deep neural network architecture for age estimation accuracy. We also introduce an attention mechanism which can adaptively learn discriminative features from the processed facial images. Experiments show that the proposed attention-based model performs better than the baseline model and achieves a reasonable performance to that with raw images in testing.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
