A new COVID-19 model at Caltech, using AI to predict the disease’s impact, is dramatically outperforming other models.

A new COVID-19 model developed at Caltech is utilizing artificial intelligence (AI) to predict the impact of the disease with remarkable accuracy, surpassing other existing models. Its exceptional performance has garnered the attention of public health officials nationwide.

AI-driven Predictions Based on Real-time Observation

Unlike traditional models that rely on designers’ assumptions, this AI-driven model incorporates real-time observations to make predictions. By utilizing AI, the model can identify hidden patterns within data sets that may go unnoticed by the human mind alone. This approach allows for more accurate predictions based on actual data rather than speculation.

Applying AI to Urgent Problems

Yaser Abu-Mostafa, professor of electrical engineering and computer science at Caltech, believes that AI is a powerful tool that should be applied to urgent global issues. Leading the development of the new CS156 model, named after Caltech’s computer science class where it originated, Abu-Mostafa emphasizes the significance of utilizing AI in tackling the pressing problem of COVID-19.

Outperforming Established Models

The accuracy of the CS156 model is being evaluated by comparing it to the ensemble model created by the Centers for Disease Control and Prevention (CDC), which incorporates 45 major models from various institutions across the country. The researchers found that as of November 25th, the CS156 model is 58% more accurate than the CDC’s ensemble model, based on 1,500 comparison points. Additionally, it consistently outperforms the benchmark projections of the Institute for Health Metrics and Evaluation (IHME).

Attracting Public Health Officials

Public health officials, including representatives from the California Department of Public Health (CDPH) and the New York City Commissioner of Health, have expressed interest in the CS156 model. Abu-Mostafa is incorporating their feedback to further enhance the model’s capabilities, aiming to provide a lifesaving tool for guiding policy decisions.

Enhancing Decision-making with Intervention Predictions

The CS156 model has been adjusted based on public health officials’ feedback to enable predictions on how interventions such as mask mandates and stay-at-home orders can control the spread of the disease. These predictions empower officials to better evaluate the situation and make interventions that are more likely to be effective. Abu-Mostafa reveals that the CDC is already utilizing predictions from the CS156 model in its decision-making process.

Expanding Data Collection and Refining Predictions

Abu-Mostafa and his team are continuously working on the CS156 model, gathering data on COVID-19 policies in every county of California since the beginning of the pandemic. Demographics play a crucial role in prediction making, as younger individuals tend to follow public health guidance less strictly than older individuals. Despite the complexities involved, Abu-Mostafa and his team are dedicated to leveraging the CS156 model to provide more accurate predictions.

Origin and Development of the CS156 Model

The CS156 model originated in Abu-Mostafa’s computer science class, CS/CNS/EE 156, Learning Systems, during Caltech’s spring 2020 term. Recognizing the opportunity to make a real impact, Abu-Mostafa and his students focused their efforts on developing a COVID-19 model. By the end of the term, they had created 40 viable models, with ten already competitive with existing epidemiological models. Throughout the summer, Abu-Mostafa and a core student group continued refining their data collection and modeling, leading to the official launch of the CS156 model on August 24th. Abu-Mostafa acknowledges the hard work of his students as a significant factor in the model’s success.

Utilizing Predictions for Decision-making and Saving Lives

Abu-Mostafa compares his work to that of a chef cooking a meal, emphasizing the importance of having the right ingredients. He hopes that the efficacy of the CS156 model will capture the attention of other public health policymakers, enabling them to utilize its predictions in their decision-making processes and ultimately save lives. Abu-Mostafa concludes by highlighting the collective goal of all COVID-19 model researchers: winning the battle against this devastating pandemic.
