Intro: What is Qokka?

See our latest presentation (also available in Chinese [中文]).

Qokka is a company focusing on the fundamental technologies of machine learning and natural language processing, and the research and development of innovative systems, algorithms, and optimizations, to make these technologies fast, reliable, and practical. Qokka aims to make these technologies accessible by everyone, and is actively creating new products powered by their core technologies.

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

Now, Qokka is refining these technologies further to build an automated information hub for cryptocurrencies and blockchain. By leveraging deep expertise and unique research breakthroughs in areas such as natural language processing, topic models, and large scale machine learning, Qokka's platform learns and summarizes information for each of thousands of cryptocurrencies from the entire Internet, including news, discussions, blogs, whitepapers, chats, social network updates, and more, ultimately providing users with a fast, simple, reliable, and more efficient way to explore large volume of information, discover high quality blockchain projects, and get high quality, timely information related to cryptocurrencies.

Core Team

Aaron Li

Founder, CEO

Aaron is the founder of Qokka. He was an engineer in machine learning at 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, made substantial contribution to all components of the platform (~100k lines of original code 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 multiple key members 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 system (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). In production settings, the system would improve efficiency and performance by 10x, and save electricity at a rate more than the regular output of a nuclear power plant.

At NICTA, he designed and implemented world's first GPU topic modelling (based on his bachelor honours 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 his 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).

She holds a master’s degree in Human-Computer Interactions and Design from University of Washington (top 3 HCI programs in the world), and completed a BS in Applied Psychology while doing HCI research at Zhejiang Sci-Tech University and Chinese Academy of Sciences. As a researcher and practitioner in HCI, she was granted patent for multiple innovative designs, and authored a diverse portfolio of publications ranging from blog articles on Medium by invitation from multiple journals, to scholarly articles in top venues such as IEEE Pervasive Computing and ACM Interactions.
