😳 AI Creates 3D Face Photos from DNA
Chinese researchers have developed an AI model called Difface that generates a 3D portrait of a person based on their DNA. The model was trained using scans and genome segments from nearly 8,000 individuals of Han ethnicity (the world's largest ethnic group, making up 91% of China's population).
The model's accuracy is still limited: each point on the DNA-based reconstructed facial scan can deviate by about 3.5 mm from its real-world position. However, when additional data such as gender, age, height, and weight are provided, the error margin drops to 3 mm.
In a test group of 2,000 people, the model accurately identified the person based on DNA in 3.3% of cases. In 42% of cases, it placed the correct individual within the top 20 most probable matches.
This is only the beginning; researchers intend to increase the model's accuracy and adapt it to different ethnic groups by training it on more diverse datasets.
If successful, Difface has the potential to be a breakthrough. Imagine scientists reconstructing the exact appearance of historical figures or police creating precise portraits of suspects from DNA found at crime scenes.
