The Challenge

As NASA prepares astronauts for more autonomous deep-space missions, understanding their cognitive state during training and operations becomes increasingly important. In isolated environments with limited communication, being able to monitor and anticipate mental focus, workload, and alertness is critical.

To explore this, NASA partnered with Topcoder to crowdsource models that can classify a trainee's current cognitive state—and predict it three seconds ahead— based on high-frequency biometric data from multiple wearable sensors. The goal was to support future mission planning by enabling real-time insights into astronaut mental states, helping improve both training effectiveness and in-mission safety.

The Solution

Topcoder hosted two Marathon Matches focused on classifying and forecasting cognitive states using sensor data with microsecond precision. Solvers delivered models capable of providing second-by-second cognitive status, even in the presence of failed or missing sensors.

Solutions included confidence scoring, sensor attribution, and robust fault tolerance, helping NASA simulate real-world edge conditions and human performance dynamics.

Challenges we ran:

• Cognitive State Determination Marathon Match

• Cognitive State Determination - Fault Tolerance Marathon Match
