Varun Ganapathi, CTO & Co-Founding father of AKASA – Interview Sequence


Varun Ganapathi is the CTO and Co-Founding father of AKASA, a developer of AI for healthcare purposes. AKASA helps healthcare organizations enhance operations, together with income cycle, to drive income, create efficiencies, and improve the affected person expertise. Varun has efficiently began two AI firms previous to AKASA, one was acquired by Google and the opposite by Udacity.

You’ve had a distinguished profession in machine studying, might you talk about a few of your early days at Stanford once you labored on making helicopters autonomous?

Once I was finding out physics as an undergrad at Stanford, I used to be additionally very excited by laptop science and machine studying (ML). To me, AI and ML mixed every part in a single – it’s actually an automatic means of doing physics on any digitizable phenomena.

For this one explicit venture, we had this helicopter that seemed like a big drone a bit smaller than a twin mattress – at a time when drones weren’t prevalent. Folks have been flying it and making it do tips, corresponding to hovering the other way up. Whereas that is very tough to do, we wished to construct an ML algorithm that would study from people how one can fly this helicopter autonomously.

We created a physics simulator that was based mostly on the precise helicopter and an ML algorithm that realized how one can predict its actions. We then utilized reinforcement studying inside the simulator to develop a controller, took the software program, and uploaded it into the precise helicopter. After we turned the helicopter on, it labored on the primary strive! The helicopter was capable of instantly hover the other way up by itself, which was fairly spectacular. The workforce continued to work on automating different kinds of tips utilizing ML.

You additionally labored at Google Books, might you talk about the algorithm that you simply labored on and the way your organization was finally acquired by Google?

I truly did an internship at Google whereas taking lessons at Stanford in 2004 – this was proper after the helicopter venture. Throughout that point, I used to be implementing ML for the Google Books venture the place we have been scanning all the world’s books.

Google was paying all these individuals to label details about the books, corresponding to pages, tables of content material, copyright, and so forth. – a really time-consuming activity. I wished to see if we are able to use ML to do that and it labored very well. It truly carried out higher and was extra correct than when people did it as a result of a lot of the errors have been resulting from human error with guide labeling.

This obtained me actually enthusiastic about ML as a result of it confirmed which you can go from human efficiency to superhuman efficiency – doing mundane duties with fewer errors and extra persistently whereas nonetheless dealing with edge instances.

From there, I made a decision to do a Ph.D. at Stanford, specializing in ML and extra theoretical papers at first. For my thesis, I developed an algorithm to carry out real-time movement seize the place a pc can observe the movement of all human joints in actual time from a depth digital camera. This was the premise for my first firm, Numovis, which targeted on movement monitoring and laptop imaginative and prescient for person interplay. It was acquired by Google.

My total journey from the helicopter venture to Google Books to self-driving vehicles and now healthcare operations actually confirmed me how highly effective and basic machine studying algorithms are.

May you share the genesis story behind AKASA?

We’ve constructed AKASA to repair an enormous, deeply embedded drawback in healthcare operations. These operations are each costly and error-prone which may result in pointless panic-inducing monetary experiences for sufferers. There was an absence of recent expertise on the executive facet and nothing being purpose-built. It grew to become clear to us that you may use expertise like AI and ML to unravel these operational challenges in an progressive means. Once we spoke to a mess of well being methods and healthcare leaders, they validated our considering which finally led to the inspiration of AKASA in 2019.

With that, AKASA’s function has been clear from the start – to allow human well being and construct the way forward for healthcare with AI. The best way we determined to tackle this problem is by combining human intelligence with modern AI and ML so well being methods can scale back working prices and allocate assets the place they matter most.

Our system-agnostic, versatile platform is presently serving a buyer base representing greater than 475 hospitals and well being methods and greater than 8,000 outpatient amenities, throughout all 50 states. Our expertise helps these organizations whether or not they’re utilizing digital well being file (EHR) suppliers like Epic, Cerner, different EHRs, or bolt-on methods, and every part in between. And we’ve achieved it with sturdy outcomes.

Our buyer base represents greater than $110 billion in mixture web affected person income, which equates to greater than 10% of all U.S. well being system spending yearly in keeping with the Facilities for Medicaid and Medicare Providers. And AKASA’s fashions and algorithms have been skilled on practically 290 million claims and remittances.

The invisible plumbing of healthcare is extraordinarily advanced, nevertheless it has an immense influence on human well being, and we’re automating it little by little.

What are among the duties that AKASA is taking a look at automating in healthcare?

Our distinctive expert-in-the-loop strategy, Unified Automation™, combines ML with human judgment and material experience to offer sturdy and resilient automation for healthcare operations. AKASA can shortly and effectively automate and streamline end-to-end duties inside the healthcare finance perform, together with invoice processing and funds. Particular duties AKASA automates embrace checking affected person eligibility, documenting and verifying insurance coverage data, estimating affected person value, modifying, rebilling, and interesting claims, and predicting and managing denials.

This sort of automation not solely reduces human error and delays for sufferers, serving to stop shock medical payments, but in addition frees up healthcare workers by taking the guide, repetitive duties totally off their plate – permitting them to deal with extra rewarding, difficult, and value-generating duties directed in direction of the affected person expertise.

What are the various kinds of machine studying algorithms which might be used?

AKASA makes use of the identical machine studying approaches that made self-driving vehicles attainable to offer well being methods with a single resolution for automating healthcare operations. This strategy – centered round ML – expands the capabilities of automation to tackle extra advanced work at scale.

We develop state-of-the-art algorithms throughout laptop imaginative and prescient, pure language understanding, and structured knowledge issues. Our platform begins with laptop vision-powered RPA and enhances it with trendy AI, ML, and an expert-in-the-loop to offer sturdy automation.

To offer a high-level overview of the way it works, our proprietary resolution first observes how healthcare workers completes their duties. Our workforce then labels that knowledge and makes use of it to coach our algorithms so our expertise can perceive and find out how healthcare workers and their methods work. From there, our platform performs these workflows autonomously. Lastly, we use experts-in-the-loop who can soar in each time the system flags outliers or exceptions. The AI repeatedly learns from these experiences, permitting it to tackle extra advanced duties over time.

May you talk about the significance of human-in-the-loop approaches and why that is set to displace RPA?

The exhausting fact is that RPA is a decades-old expertise that’s brittle with actual limits to its capabilities. It can at all times have some worth in automating work that’s easy, discrete, and linear. Nevertheless, the rationale automation efforts typically fall in need of their aspirations is as a result of life is advanced and at all times altering.

The essential strategy to RPA is constructing a robotic (bot) for every drawback or path that you simply wish to resolve. A human (marketing consultant or engineer) builds a robotic to unravel a particular drawback. This robotic resolution takes the place of a sequence of steps. It appears at a display screen, takes motion, and repeats it.

The issue that always happens is {that a} change on this planet, corresponding to a modification to a chunk of software program or UI, may cause bots to interrupt. As we all know, expertise is ever-evolving, creating dynamic environments. Which means that RPA robots typically fail.

One other drawback with these bots is that that you must create one for each state of affairs you wish to resolve. Doing this, you find yourself with many robots, all finishing very small actions that don’t require a lot talent.

It’s like a recreation of whack-a-mole. Day-after-day you face the probability that certainly one of them will break as a result of a chunk of software program goes to alter or one thing uncommon will occur – a dialogue field will pop up or a brand new type of enter will happen. The result’s pricey upkeep to maintain these bots operating. Based on analysis from Forrester, for each $1 spent on RPA, a further $3.41 is spent on consulting assets.

In different phrases, the precise software program for RPA is just not nearly all of the price. The extra appreciable value funding is all the work that it’s a must to do to maintain RPA operating on a regular basis. Many organizations don’t account for that ongoing value.

As a lot of life is advanced and continually evolving, quite a lot of work falls exterior of the capabilities of RPA, which is the place ML is available in. ML permits us to automate the exhausting stuff. And we consider the particular sauce is people who enhance the algorithms by instructing them.

When the algorithm isn’t positive about what it ought to do (low confidence), it’s escalated to a human-in-the-loop as a substitute. The people label these examples and establish instances not dealt with by the present mannequin. When that is achieved, and the AI obtained it proper, that’s a well-functioning activity.

Each activity the place a human catches an issue is a case the place the machine isn’t dealing with it correctly. On this case, knowledge is added to our knowledge set, which retrains the ML fashions to deal with this new state of affairs.

Over time, the ML mannequin builds resilience to those new edge instances. This ends in a system that’s sturdy and versatile to new outliers or exceptions, and the system will get stronger with time. This implies the automation will get higher and higher and human intervention will decline over time.

Having human specialists within the loop is essential to creating AI smarter, quicker, and higher. We want people to correctly practice the AI and be sure that it might probably deal with the outliers which might be an inevitable a part of any trade – and particularly in a dynamic subject like healthcare.

How does AKASA’s human-in-the-loop resolution Unified Automation™ work, and what are among the major use instances for this platform?

Unified Automation is a platform purpose-built for healthcare. Utilizing AI, ML, and our workforce of medical billing specialists, it creates a seamlessly built-in, custom-made resolution that helps you see worth quicker, with just about no upkeep or exception queues.

It has been designed with exceptions and outliers in thoughts. If it encounters one thing new, the platform flags the problem to AKASA’s workforce of specialists who resolve it whereas the system learns from the actions they take. It’s that human factor that differentiates us from different options available in the market and permits the platform to repeatedly study and enhance.

Unified Automation additionally adapts to the healthcare trade’s dynamic nature. It’s a seamlessly built-in, custom-made resolution that helps scale back working prices, elevates workers to deal with extra rewarding work which requires a human contact, and improves income seize for well being methods whereas additionally bettering the affected person monetary expertise.

Right here is how Unified Automation works:

Proprietary software program observes: Our Worklogger™ instrument remotely observes how healthcare workers completes their duties. Then our workforce labels that knowledge and feeds it into our automation to offer a complete view of present workflows and processes. This ends in larger visibility into workers efficiency, foundational knowledge on the workflows to energy our automation, and an correct time-per-task evaluation.

AI performs: After observing and studying the healthcare workers’s workflows, our AI then performs these duties autonomously. It repeatedly learns from issues and edge instances it runs into, taking up extra advanced duties over time. Unified Automation sits upstream within the work queue – assigning itself relevant duties and finishing them with out disrupting the workforce. It additionally mechanically optimizes processes so no set-up or intervention is required from workers.

Human experience ensures:  The system mechanically flags our workforce of medical billing specialists to deal with exceptions and outliers, coaching the AI in real-time as they work. That is the expert-in-the-loop half. With steady studying inbuilt, the Unified Automation platform will get smarter and extra environment friendly over time and the work at all times will get achieved.

Is there the rest that you simply want to share about AKASA?

We’ve got a research-first strategy which implies that our prospects have entry to modern expertise. We’re dedicated to publishing our AI and approaches in peer-reviewed publications to repeatedly set new state-of-the-art requirements for AI in healthcare operations and to steer our total trade ahead.

For instance, our analysis has been offered on the Worldwide Convention on Machine Studying (ICML), the Pure Language Processing (NLP) Summit, and the Machine Studying for Healthcare Convention (MLHC), amongst others. We’re taking a really disciplined strategy to testing our fashions and evaluating the efficiency in opposition to state-of-the-art AI approaches in the marketplace.

Our predictive denials resolution is believed to be the primary printed deep-learning-based system that may precisely predict medical declare denials by greater than 22% in comparison with current baselines. Our Learn, Attend, Code mannequin for the autonomous coding of medical claims from scientific notes has been acknowledged as defining a brand new state-of-the-art for the trade and outperformed present fashions by 18% – surpassing the productiveness of human coders. We consider these back-office improvements are essential to bettering the U.S. healthcare system at scale and can proceed to drive developments and construct custom-made options for this area.

There’s quite a lot of hype round AI in healthcare however when it comes all the way down to it, firms can overhype what their expertise can truly do. It’s loads more durable to conduct analysis to validate what the algorithms do – and we pleasure ourselves for taking this significant, but difficult path to finally show that AKASA’s Unified Automation platform is actually bringing constructive and significant change to hospitals and well being methods.

We’re excited concerning the future and what’s to return at AKASA as we construct the way forward for healthcare with AI.

Thanks for the nice interview, readers who want to study extra ought to go to AKASA.
