 # torchTextClassifiers
 
-A unified, extensible framework for text classification built on [PyTorch](https://pytorch.org/) and [PyTorch Lightning](https://lightning.ai/docs/pytorch/stable/).
+A unified, extensible framework for text classification with categorical variables built on [PyTorch](https://pytorch.org/) and [PyTorch Lightning](https://lightning.ai/docs/pytorch/stable/).
 
 ## 🚀 Features
 
-- **Unified API**: Consistent interface for different classifier wrappers
-- **Extensible**: Easy to add new classifier implementations through wrapper pattern
-- **FastText Support**: Built-in FastText classifier with n-gram tokenization
-- **Flexible Preprocessing**: Each classifier can implement its own text preprocessing approach
+- **Mixed input support**: Handle text data alongside categorical variables seamlessly.
+- **Unified yet highly customizable**:
+    - Use any tokenizer from HuggingFace or the original fastText's ngram tokenizer.
+    - Manipulate the components (`TextEmbedder`, `CategoricalVariableNet`, `ClassificationHead`) to easily create custom architectures - including **self-attention**. All of them are `torch.nn.Module` !
+    - The `TextClassificationModel` class combines these components and can be extended for custom behavior.
 - **PyTorch Lightning**: Automated training with callbacks, early stopping, and logging
+- **Easy experimentation**: Simple API for training, evaluating, and predicting with minimal code:
+    - The `torchTextClassifiers` wrapper class orchestrates the tokenizer and the model for you
+- **Additional features**: explainability using Captum

-## 🎯 Quick Start
-
-### Basic FastText Classification
-
-```python
-import numpy as np
-from torchTextClassifiers import create_fasttext
-
-# Create a FastText classifier
-classifier = create_fasttext(
-    embedding_dim=100,
-    sparse=False,
-    num_tokens=10000,
-    min_count=2,
-    min_n=3,
-    max_n=6,
-    len_word_ngrams=2,
-    num_classes=2
-)
-
-# Prepare your data
-X_train = np.array([
-    "This is a positive example",
-    "This is a negative example",
-    "Another positive case",
-    "Another negative case"
-])
-y_train = np.array([1, 0, 1, 0])
-
-X_val = np.array([
-    "Validation positive",
-    "Validation negative"
-])
-y_val = np.array([1, 0])
-
-# Build the model
-classifier.build(X_train, y_train)
-
-# Train the model
-classifier.train(
-    X_train, y_train, X_val, y_val,
-    num_epochs=50,
-    batch_size=32,
-    patience_train=5,
-    verbose=True
-)
-
-# Make predictions
-X_test = np.array(["This is a test sentence"])
-predictions = classifier.predict(X_test)
-print(f"Predictions: {predictions}")
-
-# Validate on test set
-accuracy = classifier.validate(X_test, np.array([1]))
-print(f"Accuracy: {accuracy:.3f}")
-```
-
-### Custom Classifier Implementation
-
-```python
-import numpy as np
-from torchTextClassifiers import torchTextClassifiers
-from torchTextClassifiers.classifiers.simple_text_classifier import SimpleTextWrapper, SimpleTextConfig
-
-# Example: TF-IDF based classifier (alternative to tokenization)
-config = SimpleTextConfig(
-    hidden_dim=128,
-    num_classes=2,
-    max_features=5000,
-    learning_rate=1e-3,
-    dropout_rate=0.2
-)
-
-# Create classifier with TF-IDF preprocessing
-wrapper = SimpleTextWrapper(config)
-classifier = torchTextClassifiers(wrapper)
-
-# Text data
-X_train = np.array(["Great product!", "Terrible service", "Love it!"])
-y_train = np.array([1, 0, 1])
-
-# Build and train
-classifier.build(X_train, y_train)
-# ... continue with training
-```
-
-
-### Training Customization
-
-```python
-# Custom PyTorch Lightning trainer parameters
-trainer_params = {
-    'accelerator': 'gpu',
-    'devices': 1,
-    'precision': 16,  # Mixed precision training
-    'gradient_clip_val': 1.0,
-}
-
-classifier.train(
-    X_train, y_train, X_val, y_val,
-    num_epochs=100,
-    batch_size=64,
-    patience_train=10,
-    trainer_params=trainer_params,
-    verbose=True
-)
-```
-
