The Importance of Knowing When to Stop

Objectives: Component-wise boosting algorithms have evolved into a popular estimation scheme in biomedical regression settings. The iteration number of these algorithms is the most important tuning parameter to optimize their performance. To date, no fully automated strategy for determining the optimal stopping iteration of boosting algorithms has been proposed. Methods: We propose a fully data...

When to Stop? That Is the Question

When to make a decision is a key question in decision making problems characterized by uncertainty. In this paper we deal with decision making in environments where the information arrives dynamically. We address the tradeoff between waiting and stopping strategies. On the one hand, waiting to obtain more information reduces the uncertainty, but it comes with a cost. On the other hand, stopping...

When to Stop-and-Frisk

This project was intended to demonstrate the bias that machine learning algorithms may learn. We wanted to explore the impact bias has on these algorithms and explore the methods that help correct these biases. Given data about stop-and-frisks instances, we ran several different models on the data and maximized the accuracies achieved by these models. After tuning the hyper parameters of the mo...
