Dave is the primary architect of Ersatz and an expert in deep learning and neural networks. He speaks regularly on the topic and is the organizer of the San Francisco Neural Network Aficionados meetup group.
Ersatz arose out of Dave's frustration with existing machine learning tools. Data scientists are either programmers that hate math or mathemeticians that hate programming, and he couldn't find a tool that really did both well.
Instead, he found that any machine learning pipeline involved a variety of techniques and discrete infrastructure components, and these were typically spread across a dizzying array of ever changing niche libraries and products. But what if there could be just one?! One browser-based tool you could use to solve 90% of your data science problems and scale with minimal screwing around. And so Ersatz was born.
David has a broad industrial and academic background in neural-inspired signal processing and deep neural networks, implemented in software and hardware.
He was previously CTO of BlackSwan Technologies, focused on neural network based video coding and recognition software, and an algorithm architect and team lead for Audience, Inc., an industry leader in brain-inspired speech and multisensory processing hardware for mobile devices. He has also contributed to and advised projects applying deep learning to large scale environmental monitoring, and brain-computer interface.
David received his bachelor of EE degree at Georgia Tech, his Ph.D. research at the University of Maryland, College Park, and was an academic AI researcher at ETH Zurich.
Ronjon Nag, PhD
Ronjon is an early investor, co-founder, and Chief Strategy Officer. He is a seasoned entrepreneur and has 30 years of experience working with neural networks.
He co-founded Lexicus, a company that created software for the earliest smartphones and included functionality for predictive text, speech, and handwriting recognition. The company was acquired by Motorola.
Following the acquisition, he co-founded Cellmania, a company that focused on mobile app store infrastructure software. The company was acquired by BlackBerry (formerly RIM).
He has a PhD in engineering from Cambridge University, a Masters from MIT, was a Harkness Fellow at Stanford's Rumelhart lab in the Psychology Department, and has been featured on the cover of Fortune magazine for his early work with neural networks.
