Lack of Data
There should be enough information for the training, Decision trees need many examples to accomplish this. So, if you have a small dataset, the model can fail at the inference stage with the new data.
- Example: Provide a scenario where insufficient data led to model failure.
- Prevention: Ensure you have enough data for training, especially for decision trees which require many examples.
