14th of October, Hong Kong - Insilico Medicine, a biotechnology company developing an end-to-end drug discovery pipeline utilizing next-generation artificial intelligence, is proud to present its paper "A Prior of a Googol Gaussians: a Tensor Ring Induced Prior for Generative Models" at the 33rd Conference on Neural Information Processing Systems (NeurIPS).
Generative models produce realistic objects in many domains, including text, image, video, and audio synthesis. Most popular models, such as Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs), usually employ a standard Gaussian distribution as a prior. It was previously shown by research that a richer family of prior distributions may help to avoid the mode collapse problem in GANs and to improve the evidence lower bound in VAEs.
Insilico scientists proposed a new family of prior distributions: Tensor Ring Induced Prior (TRIP) that packs an exponential number of Gaussians into a high-dimensional lattice with a relatively small number of parameters. They showed that this prior improves Fréchet Inception Distance for GANs and Evidence Lower Bound for VAEs. They also studied generative models with TRIP in the conditional generation setup with missing conditions.
"We are excited to present a novel prior distribution that can be used in any generative model, including variational autoencoders (VAE) and generative adversarial networks (GAN)," said Daniil Polykovskiy, Senior Research Scientist at Insilico Medicine.
Recently, Nature Biotechnology published a paper by Insilico Medicine scientists and collaborators that described the use of a Generative Tensorial Reinforcement Learning (GENTRL) model to propose molecules that would bind to DDR1 kinase. These molecules were later synthesized and experimentally validated in cells and animals.
"Earlier this month, we published our work in Nature Biotechnology describing an unprecedented experimental validation of generative machine learning pipeline. Now, this model, improved and distilled to its mathematical core, will be showcased at the most impactful AI conference in the field. We continue transforming early-stage drug discovery while delivering strong research results in theoretical machine learning." - said Alex Zhebrak, CTO of Insilico Medicine.
"We are very excited to have a paper by Insilico scientists accepted at NeurIPS, one of the elite conferences on artificial intelligence. Insilico is focused on extending human life by accelerating and improving the drug discovery process, and we are proud to have some of the most creative AI teams in the industry to help us do this," said Alex Zhavoronkov, PhD, founder, and CEO of Insilico Medicine.
Insilico was the Gold Sponsor of ICML 2018 and NeurIPS 2018. This year it will host a reception near the conference venue as the company seeks to recruit the best bioinformatics and deep learning talent to focus on target identification, small molecule generation, and prediction of clinical trials outcomes.
The Conference on Neural Information Processing Systems (NeurIPS) is a machine learning and computational neuroscience conference held every December. The conference includes invited talks as well as oral and poster presentations of accepted papers. In 2018-2019 the registrations were sold out in less than 12 minutes. The conference is scheduled to be held Dec 8th through the 14th, 2019 at Vancouver Convention Center.
