IndoBERT-GRU for Bot Detection on Platform X

This model uses MBERT to classify Twitter/X accounts as bots or humans based on their textual content and numeric features.

Model Architecture

Base Model: bert-base-multilingual-cased
Classifier: 2-layer feedforward with ReLU + Sigmoid

Dataset

The dataset includes Indonesian tweets with labels (0 for human, 1 for bot), along with additional numeric features such as favorite_count, retweet_count, reply_count, and quote_count.

Training Details

Loss Function: Binary Cross Entropy (BCELoss)
Optimizer: AdamW (lr = 2e-5)
Epochs: 10
Max Token Length: 128
Batch Size: 16
