Example discussion approaches

It is a completely normal thing to feel lost in a competition at some point: you came in, tried a few ideas, got some traction on the leaderboard, and then you hit the Kaggle version of a runner’s wall. This is the moment when discussion forums are the place to consult.

As an example, we will look at the Optiver Realized Volatility Prediction competition (https://www.kaggle.com/c/optiver-realized-volatility-prediction), characterized by the organizers like this:

In the first three months of this competition, you’ll build models that predict short-term volatility for hundreds of stocks across different sectors. You will have hundreds of millions of rows of highly granular financial data at your fingertips, with which you’ll design your model forecasting volatility over 10-minute periods. Your models will be evaluated against real market data collected in the three-month evaluation period after training.
