Hi,
I have trained a model about face classfication with caffe-jacinto. I have test the accuracy of the model on pc, it is 95%.
I am using the TIDL tool to quantize the model with 8 bit, and then, I did the forward propagated on my device platform, the accuracy is 90%.
I think the accuracy loss too much, so I try to 12 bit quantize, but the problem is that I don't know how to output the feature map of 12bit quantize.
the 8 bit quantize, the feature map vector is -128 to 128, we could use the signed char* to point the output buffer.
how about 12bit, I think them are -2048 to 2048, so we try to use the short* to point the output buffer.
but the result is not right, the value of feature are exceed 2048, so I am confused.
thanks
best regards
