**Data Preprocessing**

 I used the load_dataset function to load all the patent applications that were filed to the USPTO in January 2016. We specify the date ranges of the training and validation sets as January 1-21, 2016 and January 22-31, 2016, respectively. This is a smaller dataset.

 There are two datasets: train and validation. Here are the steps I did:

 - Label-to-index mapping for the decision status field
 - map the 'abstract' and 'claims' sections and tokenize them using pretrained('distilbert-base-uncased') tokenizer
 - format them
 - use DataLoader with batch_size = 16

**milestone3:**

The following notebook has the tuned model. There are 6 classes in the Harvard USPTO patent dataset and I decided to encode them as follow:

decision_to_str = {'REJECTED': 0, 'ACCEPTED': 1, 'PENDING': 1, 'CONT-REJECTED': 0, 'CONT-ACCEPTED': 1, 'CONT-PENDING': 1}

so that I can get a patentability score between 0 and 1.

I use the pertained-model 'distilbert-base-uncased' from the Hugging face hub and tune it with the smaller dataset.

My tuned model's performance is not good but I ran out of time. =(

I tested my shared model here: https://github.com/aye-thuzar/CS670Project/blob/main/CS670_Examples.ipynb


**milestone 4**

This is the landing page for milestone 4 : https://sites.google.com/view/cs670-finetuning-language-mode/home

The documentation for milestone 4: https://github.com/aye-thuzar/CS670Project/blob/main/milestone4Documentation.md

I did not get a chance to fix my video, so it only has the model before I tuned it. After my tuned it, my model is only showing a patentabiilty score no matter which texts, I put for abstract and claims. =(
