Abstract
Deep Neural Networks (DNNs) demonstrated superior accuracy over conventional methods in numerous problems including but not limited to image recognition, speech recognition, text translation, and self-driving cars. However, DNNs are comprised of billions of parameters, which renders the task of training them a challenge given the traditional computing platforms like CPUs. In this proposal, we compare various approaches to DNN hardware accelerators. Dense hardware accelerators offer high throughput but fail to capture the redundant nature of DNNs. Sparse hardware accelerator solutions utilize this redundancy but face challenges in implementation due to increased architectural complexity. Software solutions promise a good trade-off to use sparsity while executing on efficient dense hardware.
