Prediction Models
Sources:
Here are key points from expert discussions on predictive models across different fields:
-
Criminal Justice:
- Predictive models can have biases based on the data they are trained on. For example, there can be disparities in how different groups are treated based on observed crime rates and arrest records. These biases may lead to wrongful predictions and judgments 1 .
-
Clinical Settings:
- AI models for clinical predictions may show high accuracy in specific trials but fail to generalize to broader contexts. This brittleness is due to over-specialization during fine-tuning, making them less reliable outside controlled environments 2 .
- A mortality prediction tool uses electronic health record variables to predict 180-day mortality, triggering timely clinical interventions. The 180-day window strikes a balance between short enough for relevant action and long enough for meaningful predictions 3 .
-
Economic Forecasting:
- Economic models face challenges in accurately relating parameters with outcomes due to the complexity of social behaviors. These models often have varying predictions, indicating the need for further refinement and understanding of complex systems 4 .
-
Climate Change:
- Climate models have been critiqued for over-predicting warming trends over the last 35 years but have been accurate in other aspects, like the relation between CO2 levels and temperature rise. However, some phenomena, like the rapid loss of Arctic sea ice, were not accurately predicted, indicating room for improvement in the models 5 6 .
-
Health and Wearables:
- Predictive models in health use correlations to forecast future events based on historical and real-time data from wearables. Increasing data collection and improving AI algorithms can enhance the predictive power and precision of these models 7 .
These insights emphasize the strengths and limitations of predictive models across various domains.
