+ ## Training the Model 🧠
340
+
341
+ bert-local is trained using **bert-mini** for multi-class text classification. Here’s how to train it:
342
+
343
+ ### Prerequisites
344
+ - Dataset in CSV format with `text` (query) and `label` (category) columns.
345
+ - Example dataset structure:
346
+ ```csv
347
+ text,label
348
+ "Need help with taxes","accounting firm"
349
+ "Where’s the nearest airport?","airport"
350
+ ...
351
+ ```
352
+
353
