Centaur AI Combines Human Expertise with Machine Learning for Healthcare Innovation


TL;DR Breakdown

  • Centaur AI combines the power of AI machines with human intellect to maximize both strengths.
  • Two complementary approaches to AI are: data-driven and knowledge-driven.
  • Centaur AI is a hybrid arrangement that combines human intelligence and computational power to solve complex healthcare problems.

Healthcare will gain greatly as AI technology develops and advances. The application of AI in healthcare has already shown a variety of advantages, including increased diagnostic precision, more individualized treatment regimens, and higher prediction skills.

Centaur AI refers to a combination of AI machine power and human intellect. This approach is seen as a way to maximize the strengths of both AI and human healthcare professionals. With Centaur AI, machines can assist with tasks such as diagnosis and treatment planning, while human healthcare professionals can provide the necessary context and interpretation to make informed decisions.

AI Approaches for Optimizing Backend Functioning

There are two different yet complementary approaches to AI.

First Approach for AI

The first approach for AI is described as relying on the belief that given sufficient data and computing power, complex models can be created to perform challenging tasks, even those that are typically performed by humans. This approach emphasizes that domain expertise may not be necessary and that data and computing power alone are sufficient to solve problems.

Examples of this approach include training a computer to produce a painting in the style of Claude Monet or teaching a robot to bake cookies using data. The development of self-driving cars is also referenced as an example of this approach, which heavily relies on computing power and the availability of large amounts of data.

Second Approach for AI

The second approach for AI involves imitating how humans reason using concepts like connection and causality. This approach emphasizes the critical importance of domain expertise and building algorithms that can apply approximations of accumulated human knowledge to solve problems. The algorithms, also known as expert systems, typically rely on rule-based or probabilistic calculations.

The knowledge camp, which supports this approach, believes that expert systems are essential for replicating human reasoning and decision-making in AI. These systems require a deep understanding of a specific domain to be effective and use approximations of human knowledge to solve problems.

Comparison of the First and Second Approaches to AI

The development of data-driven AI has surpassed that of knowledge-based AI due to the complexity of rule-based expert systems, which can impede scalability. Data-based systems, such as those used in self-driving cars and big tech companies for ad placements, messaging, and recommendations, have seen significant advancements. In the field of biology, data-driven AI has also made important contributions to solving complex problems.

Domain knowledge, however, may be more crucial in evaluating the signal-to-noise problems that develop with big data when it comes to the complexity of human biology and disease. In order to address the enormous complexity of the human body, it is likely that a combination of data-driven and knowledge-driven approaches will be required.

The requirements of computer gaming, which provided the commercial forces that spurred computational innovation, can be blamed for the rapid evolution of neural network techniques. A race to enhance technology was started by the requirement for realism and real-time responsiveness in gaming. 

Andrew Ng was among the first to recognize and leverage the power of GPUs to help neural networks bridge the gap between the human brain and computers. By using ultrafast matrix representations and manipulations made possible by GPUs, computers could create algorithms that automatically improved as they processed data. In other words, GPUs help computers learn to learn.

What Is Deep Learning?

Artificial neural networks that are far deeper and more complicated than earlier networks are used in deep learning. In the past, neural networks frequently included a single hidden layer between the input data and the predictions they produced. Deep neural networks of today, however, might have tens or even hundreds of layers, each with non-linear functions.

The depth of these networks allows them to represent extremely complex relationships among data, as each layer can detect and analyze different features of the input data. As the number of layers has increased, so has the capacity. 

How is Centaur AI going to change the healthcare game? 

The Centaur AI system is a hybrid arrangement that combines human intelligence and computational power to provide the best of both worlds. It is particularly useful in areas where complex human nuances are a significant factor, and brute computational force is not enough to solve problems in a closed, fully specified system like a game.

A network of medical experts and students from more than 140 nations has been established by Centaur. This network mostly operates on the iOS app DiagnosUs, a gamified platform where labelers develop their abilities and compete with one another. The purpose of the software is to evaluate the labelers’ performance and award the most accurate ones with financial rewards.

It’s significant to note that Centaur gathers numerous perspectives on each instance, with more opinions being acquired on the trickier cases. After that, the platform carefully integrates different viewpoints to provide classifications that are more accurate than those provided by a single expert. The site gathers more than a million opinions each week.

AI learns by millions of examples

Similar to humans, AI learns by example; therefore, training an algorithm necessitates dozens or even millions of examples. Large medical datasets, however, are challenging to curate, and it is practically impossible to find appropriate labels from sources with relevant medical expertise and specialized training. The Centaur platform is meant to grow quickly to millions of labels and serve a broad range of specialized medical applications.
