are you just trying to annoy me?

Chinese Chip Ecosystem and Overseas Penetration​

There is this narrative that this regulation hampers Nvidia and other western semiconductor firms internationally versus China and creates a new market for China.

To be clear this is FUD.

China cannot produce enough AI chips for domestic needs this year or next year or the year after that. The western ecosystem demands are >5 million a year. China’s if they wish to be competitive must be in that order of magnitude with competitive chips. They are not anywhere close yet.

16k is the number it took to train Llama. Atleast that number is authentic because others might guard their training resources closely.

Is that number in the millions?
of course, why do people keep asking me these questions.

I said they have enough.

exactly, training is clearly not a problem. So inference is needed and the Ascend chips are fine for inference.

GDiffRetro: Retrosynthesis Prediction with Dual Graph Enhanced Molecular Representation and Diffusion Generation.​


Abstract

Retrosynthesis prediction focuses on identifying reactants capable of synthesizing a target product. Typically, the retrosynthesis prediction involves two phases: Reaction Center Identification and Reactant Generation. However, we argue that most existing methods suffer from two limitations in the two phases: (i) Existing models do not adequately capture the “face” information in molecular graphs for the reaction center identification. (ii) Current approaches for the reactant generation predominantly use sequence generation in a 2D space, which lacks versatility in generating reasonable distributions for completed reactive groups and overlooks molecules’ inherent 3D properties. To overcome the above limitations, we propose GDiffRetro. For the reaction center identification, GDiffRetro uniquely integrates the original graph with its corresponding dual graph to represent molecular structures, which helps guide the model to focus more on the faces in the graph. For the reactant generation, GDiffRetro employs a conditional diffusion model in 3D to further transform the obtained synthon into a complete reactant. Our experimental findings reveal that GDiffRetro outperforms state-of-the-art semi-template models across various evaluative metrics.​
