Show HN: A JavaScript budgeting app that implements a KNN to make predictions
- heinrichhartman 8y agoThat's neat. I am thinking about building something similar just with scanned invoices. I hope that using KNN on some image features can auto-classify the invoice into existing categories well enough...
- grenoire 8y agoNot very common for personal finances but there are already services (AutoEntry, Trifact365 etc.) that handle this kind of categorisation for small businesses with OCR, no need for NN.
- grenoire 8y agoIt's an interesting assumption to correlate prices with categories, I think this'll suffer greatly from omitted variable biases. If I end up having to check each time whether or not the number entered has changed the category, then I'm not sure that it's better than just keeping in manual.
