The field of hardware acceleration and neural network optimization is witnessing significant advancements, particularly in the areas of design space exploration, low-bit quantization, and the integration of temporal information into neural network models. Innovations are focusing on overcoming the limitations of traditional methods through the application of machine learning and novel hardware structures. For instance, learning-based techniques are being developed to navigate the complex and non-uniform design spaces of deep neural network accelerators more efficiently. Similarly, the introduction of extreme low-bit quantization methods is enabling more power and area-efficient hardware designs without substantial accuracy loss. Additionally, the exploration of temporal information in neural networks is opening new avenues for processing event-based data with higher efficiency and lower energy consumption.
