Operation-specific APIs proposal use cases and requirements (Ping, Jonathan): https://github.com/webmachinelearning/proposals/issues/2


Discuss high-level requirements for WebNN API (Ningxin, Chai):

  *   Req: Direct access to the convolution op

  *   Addressed by: https://github.com/webmachinelearning/webnn/pull/149#discussion_r591634607


  *   Req: Support for native tensor types, GPU buffers

  *   Addressed by https://github.com/webmachinelearning/webnn/pull/149 for GPU buffers

  *   Req: Device preference setting when compiling a graph to reduce IO between accelerators

  *   Addressed by: ?

  *   Req: Optimization for single-op graph execution

  *   Addressed by: ?

Proposal to spin these high-level requirements for WebNN API into its own issue to be resolved.
