Write a Distribution Analysis Function
See
mainrun_train_test.py
for the incomplete function.This function should calculate how often each intent and slot appears in the dataset.
Think about what fields in the dataset you’ll need:
Intent: Directly accessible as
example['intent']
.Slots: Comes from
example['slots']
but might need to be flattened into a single list.
Use a counting method to track the frequency of intents and slots.
Tips:
Use tools like
collections.Counter
for efficient counting.Ensure your function handles edge cases, such as examples without any slots.
Run the Function on Training and Testing Data
Call your distribution function for both datasets.
Print the results to inspect the frequency of each intent and slot.
Tips:
Compare the distributions of training and test datasets.
Look for imbalances or unexpected gaps. For example:
Are certain intents or slots underrepresented or missing?
Does the test set mirror the training set?
Interpret the Results
Once you have the distributions, analyze them to answer key questions:
Which intents or slots are the most frequent? The least?
Are there any imbalances that might cause the model to focus too heavily on common labels?
Are rare intents or slots important for the system’s performance?
Reflect on how these observations might affect training.
Tips:
If rare intents or slots are crucial, consider strategies like data augmentation or using weighted loss functions during training.
If the test distribution doesn’t match the training distribution, think about how this might affect evaluation.
