Sana’s technology makes innovative use of recurrent neural networks and reinforcement learning. These models take content, answers, response times and an array of contextual information as inputs, before processing these inputs through a number of different network layers containing millions of neuron-like connections. One neural network, – the “prediction network” -, predicts how the student will interact with content. Another -, the “planning network” – , selects the content that will result in the highest increase in engagement and proficiency over time.

The model incorporates features about the student such as proficiencies, assessment needs, need for remediation, and where to move forward;, about the response and behavior such as pace, repetition, engagement and preferred strategies as well as about the content such as asset relationships, instructional value, assessment value, difficulty, and duration. Capturing a rich and accurate representation of students and content from hundreds of millions of data points.

Personalized education is proven to produce learning gains for the average student to the order of two standard deviations. Our mission is to apply recent breakthroughs in deep learning to make personalized education accessible to everyone — providing these benefits on a global scale.

Currently, Sana Labs is working with digital education companies around the world with over 70 million students in their platforms. Consequently, Sana Labs has access to massive data-sets on how people learn, creating immense data network effects as well as a thorough understanding of how to best train models and algorithms to optimize each student’s learning outcomes.

• World-class engineers and researchers – At Sana Labs, we are a team of world-class engineers and researchers with an extensive experience of putting algorithms in production, within a vast amount of fields. Our teams’, backgrounds include experience at Imperial College, CERN, Google, and Spotify.
• Unbeatable Time to Market – Our API makes integration with any architecture and content simple so that personalization features can be production-ready within days, not months.
• Best in Class Results – Sana Labs has received independent recognition for its solution, including 1st Place in the Duolingo Global AI Benchmark Challenge, and 1stplace in the ASSISTment Global AI Benchmark Challenge.

The global education industry is vast (valued at over $6 trillion in 2016), and is undergoing a sea change through the move to digital and online instruction, materials and modalities. This shift is enabling a progression towards what many educators consider to be the holy grail of learning — universal personalized, adaptive instruction and assessment. With our solution, we aim to be the engine that drives forward this change — fundamentally improving the function of the entire industry, directly affecting hundreds of millions of people’s lives every day through personalizing education at scale.
