Hearing instruments are supported by multicore processor platforms that include several digital signal processors (DSPs). These resources can be used to implement neural networks (NNs); however, execution time and energy consumption are prohibitive to do so. In this presentation, we will talk about benchmarking neural network workloads relevant for hearing aids on Demant’s DSP-based platform. We will also introduce a custom NN processing engine (NNE) that was developed to achieve further power optimizations by exploiting a set of various techniques (reduced wordlength, several MACs in parallel, two-step scaling etc.).
A pretrained, fully connected feedforward NN (Hello Edge: Keyword Spotting on Microcontrollers) was used as a benchmark model to run a keyword spotting application using Google speech command dataset on both, the DSP and NNE. We will talk about the performance of the two implementations, where the NNE significantly outperforms the DSP solution.
Zuzana graduated from Technical University of Denmark (DTU) in 2019 as a MSc of Computer Science and Engineering. Since then she has been pursuing a Ph.D. degree in collaboration with DTU and Demant A/S - an international hearing healthcare group that offers solutions and services to help people with hearing loss. The topic of Zuzana’s Ph.D. are neural networks in resource constraint hearing instruments with the focus on hardware and digital design.
TinyML is incredibly exciting, but if you’re hoping to train your own model it can be difficult to know where to start. In this talk, Dan walks through his workflow and best practices for training models for three very different types of data: time-series from sensors, audio, and vision. We’ll be using Edge Impulse, a free online studio for training embedded machine learning models.
Daniel Situnayake is the Founding TinyML engineer at Edge Impulse. He’s co-author of the O’Reilly book TinyML, alongside Pete Warden. He previously worked on the TensorFlow team at Google, and he co-founded Tiny Farms Inc., deploying machine learning on industrial scale insect farms.
