• Integration of tolerance-aware mechanisms within the neural network's learning framework.
• Experimental validation using simulations or hardware implementations to assess performance.

Main Results:

• Demonstrated reduction in performance degradation caused by weight variations.
• Quantified the improved robustness of the neural network under hardware tolerances.
• Experimental evidence supporting the efficacy of the proposed tolerance-aware learning algorithm.

Conclusions:

• The proposed learning algorithm effectively mitigates the impact of hardware implementation errors on neural network performance.
• This approach offers a robust solution for deploying neural networks in real-world hardware with technological limitations.
• The findings highlight the importance of considering hardware constraints during the neural network design and training phases.
