chrishkchris opened a new pull request #478: Singa 473 (Implement ONNX Operators in Autograd: Trigonometry functions) URL: https://github.com/apache/incubator-singa/pull/478 This PR corresponds to JIRA ticket SINGA-473 (Implement ONNX Operators in Autograd: Trigonometry functions). The Open Neural Network Exchange (ONNX) is a format for interchanging neural network models between AI systems. There is a list of ONNX operators defined in https://github.com/onnx/onnx/blob/master/docs/Operators.md In this PR, we are going to implement more ONNX operators in our Autograd module (incubator-singa/python/singa/autograd.py). First of all, this ticket implements 11 unary Trigonometry functions in the Autograd module, which are: 1. cos 2. cosh 3. sin 4. sinh 5. tan 6. acos 7. acosh 8. asin 9. asinh 10. atan 11. atanh
