Reducing the data width from 8 to 4 bits only reduces prediction accuracy by 11%, but the FPGA area decreases by 41%. Compared to networks that use the sigmoid functions, our proposed D-ReLU function uses 24% - 41% less area with no loss to prediction accuracy. Dec 09, 2018 · The accuracy is around 90%. This time, the model is very rough. This was to be expected. simple_history. model. evaluate (reshaped_test_data, to_categorical (test_label)) [1] 0.8953 Apparently, Kuzushiji-MNIST looks quite odd. But by following the same manner to MNIST, we can make simple classification model. This is not strange data set at all.
The MNIST handwritten digit data set is widely used as a benchmark dataset for regular supervised learning. While a 2-D image of a digit does not look complex to a human being, it is a highly inefficient way for a computer to represent a handwritten digit; only a fraction of the pixels are used.
