Baidu
Investors must note: Baidu's AI is a general-purpose API designed for commercial scale (handling millions of support calls), not a precision instrument for scientific discovery.
- Accuracy Contrast: Baidu's "90%+" claim is based on internal commercial benchmarks. Noldus's ~99% accuracy is the scientific gold standard, validated by 26,000+ peer-reviewed publications and the NIH.
- Application Gap: You cannot use Baidu's API to pass FDA drug approval because it is an untraceable "black box." Noldus FaceReader provides frame-by-frame FACS coding, making it the legal standard for global psychological and pharmacological research.
