The classification task is split into two stages:
1. URL features model
    - **96.5%+ accuracy** on training and validation data
    - 2,436,727 rows of labelled URLs
2. Website features model
    - **100.0% accuracy** on training and validation data
    - 911,180 rows of 43 features

## Training Features
I applied cross-validation with `cv=5` to the training dataset to search for the best hyperparameters.
Here's the dict passed to `GridSearchCV`:
```python
params = {
    'objective': 'binary',
    'metric': 'binary_logloss',
    'boosting_type': ['gbdt', 'dart'],
    'num_leaves': [15, 23, 31, 63],
    'learning_rate': [0.001, 0.002, 0.01, 0.02],
    'feature_fraction': [0.5, 0.6, 0.7, 0.9],
    'early_stopping_rounds': [10, 20],
    'num_boost_round': [500, 750, 800, 900, 1000, 1250, 2000]
}
```
To reproduce the 100.0% accuracy model, you can follow the data analysis in the dataset page to filter out the unimportant features.
Then train a LightGBM model using the most suited hyperparamters for this task:
```python
params = {
    'objective': 'binary',
    'metric': 'binary_logloss',
    'boosting_type': 'gbdt',
    'num_leaves': 31,
    'learning_rate': 0.01,
    'feature_fraction': 0.6,
    'early_stopping_rounds': 10,
    'num_boost_round': 800
}
```


## URL Features
```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("FredZhang7/malware-phisher")
model = AutoModelForSequenceClassification.from_pretrained("FredZhang7/malware-phisher")
```
## Website Features
```bash
pip install lightgbm
```
```python
import lightgbm as lgb
lgb.Booster(model_file="phishing_model_100.0%_train+val.txt")
```
