Feb 4, 2018: New version of Sudo Review is launched! It's our product-review exploration product, powered by latest versions of Qokka's core machine learning engines and visualizations. Check it out at

Intro: What is Qokka?

See our latest presentation (also available in Chinese [中文]). It has pointers to a list technical papers we published in the past, and a draft whitepaper in progress.

Qokka is a company focusing on the fundamental technologies of machine learning and natural language processing, researching and developing innovative systems, algorithms, and optimizations, to make these technologies fast, reliable, and practical. Not only we create new technologies, we also build products with them for mass adoption, so we can empower people with these technologies and improve their everyday life.

Qokka's first product is an information summarization platform for Amazon product reviews, launched in Feb 2018, available at

Now, Qokka is refining these technologies further, to build an automated information hub for cryptocurrencies and blockchain, aiming to provide individuals with a fast, transparent, reliable, intelligent, and real-time channel to explore large volume of information, and discover high-quality crypto projects. AI and blockchain are built by the people, for the people. It should not be the case that only the rich players get provided with high quality, timely information in such a space with explosive growth. Everyone should have open, equal opportunities.

Qokka empowers average users through AI, by making blockchain and crypto information more transparent and readily available. Qokka utilizes AI technologies such as natural language processing, topic models, and large scale machine learning, to learn and summarize information for each of thousands of cryptos from the entire Internet, including news, discussions, blogs, whitepapers, chats, social networks, and more, ultimately providing individuals and average users a fast, simple, and more efficient way to explore information.

Coming soon. Sign up for beta here.

Core Team

Aaron Li

Founder, CEO

Aaron is the founder of Qokka. He was an engineer in machine learning at the Google Research (on core ML systems), NICTA (Australia's national lab, now part of CSIRO), and a lead engineer in the founding team at Scaled Inference, an AI startup founded by early Google veterans, backed by Vinod Khosla, David Wallerstein, and Michael Jordan.

At Scaled Inference, he co-designed and co-implemented, the first autonomous optimization platform. He progressed from an inference engineer, to a leader heading the research and engineering of AI and ML in the company. He co-developed learning, inference, optimization, evaluation, and analysis of a new paradigm of high-dimensional mixture model families, which are as powerful as deep learning but require far less data, are more expressive, explainable, and mathematically sound. He joined as the #7 member in the company, contributed substantial amount of code to all parts of the platform (~100k lines in total), conducted 300+ interviews, and recruited multiple star engineers, scientists, and PhDs from top programs as part of his team and the company, including every person in the current technical leadership team (as of 2017-2018).

At Google's core research group Strategic Technologies, he designed and implemented world's first fast, large-scale general topic modelling (an extension to his KDD 2014 paper) on Google's proprietary parameter server large-scale machine learning infrastructure (which itself was built by the team based on his NIPS 2013 paper), which in production settings, would improve efficiency and performance by 10x, and save an amount of electricity more than the normal output of a nuclear power plant.

At NICTA, he designed and implemented world's first GPU topic modelling (based on his thesis and proprietary code) and comparative visualization of topic models, which he integrated into NICTA's product "OpinionWatch", a project sponsored by Australia Department of Defence. He represented the team and presented the research and the new product at Parliament House during Techfest 2013, a special event hosted by Prime Minister of Australia.

He won multiple nationally and internationally recognized awards, including the prestigious ACM SIGKDD 2014 Best Research Paper Award on machine learning and topic modeling while completing his M.S. in Language Technologies (Computer Science) at the Carnegie Mellon University, an area he has been working on since before he finished his B.S. at Australian National University with quadruple majors in Computer Science, Computer Science, Mathematics, and Statistics. He started programming since the age of 7.

A Beijing native, New Zealand citizen, and former resident of Australia, Aaron immigrated to United States and was granted ""Extraordinary Ability green card (EB-1A)" (a.k.a. Einstein Green Card) in the US to create fundamental, disruptive technologies for humans. He started mining Bitcoin since 2011 (recent talks, slides, interviews, and blogs).
