Figure Lengend Snippet: Noise modeling, training accuracy comparison, and fixed-point saturation behavior (A) Illustration of impulse noise modeling in the MNIST dataset. From left to right: original image, image corrupted with random impulse noise (random positions and random values), and image corrupted with impulse noise (random positions with pixel values replaced by either 0 or 255). (B) Training accuracy comparison among six different network configurations and quantization settings on the clean MNIST training dataset. Accuracy is reported per 100-image chunk. (C) Evolution of final output scores under different fixed-point formats during training. Results are shown for FPGA Q6.10 (left) and Q6.26 (right) implementations. The x axis denotes the uniformly sampled time step index selected from the first 180 training chunks of the hardware simulation, and the y axis represents the final output score S o j . At each sampled time step, the maximum, mean, and standard deviation of S o j across all output neurons are computed and visualized.
