# CryptoBERTRefined
CryptoBERTRefined is a fine tuned model from [CryptoBERT by Elkulako](https://huggingface.co/ElKulako/cryptobert) model.

# Classification Example
Input:
```python
!pip -q install transformers
from transformers import TextClassificationPipeline, AutoModelForSequenceClassification, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("AfterRain007/cryptobertRefined", use_fast=True)
model = AutoModelForSequenceClassification.from_pretrained(model_name, num_labels = 3)
pipe = TextClassificationPipeline(model=model, tokenizer=tokenizer, max_length=128, truncation=True, padding = 'max_length')

post_3 = "Because Forex Markets have years of solidity and millions in budget, not to mention that they use their own datacenters. These lame cryptomarkets are all supported by some Amazon-cloud-style system. They delegate and delegate their security and in the end, get buttfucked..." 
post_2 = "Russian crypto market worth $500B despite bad regulation, says exec https://t.co/MZFoZIr2cN #CryptoCurrencies #Bitcoin #Technical Analysis" 
post_1 = "I really wouldn't be asking strangers such an important question. I'm sure you'd get well meaning answers but you probably need professional advice."

df_posts = [post_1, post_2, post_3]
preds = pipe(df_posts)
print(preds)
```
Output:
```python
[{'label': 'Neutral', 'score': 0.8427615165710449}, {'label': 'Bullish', 'score': 0.5444369912147522}, {'label': 'Bearish', 'score': 0.8388379812240601}]
```

# Training Corpus
Total of 3.803 text have been labelled manually to fine tune the model, with consideration of non-duplicate and a minimum of 4 words after cleaning. The following website were used for our training dataset:
1. Bitcoin tweet dataset from [Kaggle Datasets](https://www.kaggle.com/datasets/kaushiksuresh147/bitcoin-tweets) (Randomly picked).
2. Labelled crypto sentiment dataset from [SurgeAI](https://www.surgehq.ai/datasets/crypto-sentiment-dataset).
3. Reddit thread r/Bitcoin with the topic "Daily Discussion" (Randomly picked)

Data augmentation was also performed to enrich the dataset, Back-Translation was used with Google Translate API on 10 language ('it', 'fr', "sv", "da", 'pt', 'id', 'pl', 'hr', "bg", "fi").
