Google wins partial victory in AI training copyright lawsuit, with a US federal judge ruling that the company's use of deep learning algorithms in its AlphaGo AI system did not infringe on a copyright held by a Chinese company, Carnegie Mellon University. The judge's decision was based on the fact that Google's use of the algorithms was for educational purposes, rather than commercial gain. The ruling is a significant victory for Google, which had faced a lawsuit alleging that its use of the algorithms infringed on Carnegie Mellon's copyright.
