+# Diffusion Models: Complete DDPM Implementation
+
+A comprehensive PyTorch implementation of Denoising Diffusion Probabilistic Models (DDPM) with detailed mathematical foundations and educational content.
+
+## Model Description
+
+This repository contains a complete implementation of Diffusion Models (DDPM) trained on 2D synthetic datasets. The model learns to generate new data points by mastering the art of noise removal through a reverse diffusion process. This implementation serves as both a working model and an educational resource for understanding the mathematics and implementation of diffusion models.
+
+### Architecture Details
+
+- **Model Type**: Denoising Diffusion Probabilistic Model (DDPM)
+- **Framework**: PyTorch
+- **Input**: 2D point coordinates
+- **Diffusion Steps**: 1000 timesteps
+- **Hidden Dimensions**: 256 units with SiLU activations
+- **Time Embedding**: 64-dimensional rich representations
+- **Total Parameters**: ~130K
+- **Model Size**: 1.8MB
+
+### Key Components
+
+1. **Noise Predictor Network**: Neural network that predicts noise ε_θ(x_t, t)
+2. **Forward Diffusion Process**: Gradually adds Gaussian noise over T steps
+3. **Reverse Diffusion Process**: Iteratively removes noise to generate samples
+4. **Time Embedding Module**: Converts timesteps to rich feature representations
+
+## Training Details
+
+- **Dataset**: Synthetic 2D point clusters
+- **Diffusion Steps**: 1000
+- **Beta Schedule**: Linear (0.0001 to 0.02)
+- **Optimizer**: AdamW with cosine annealing
+- **Learning Rate**: 0.001
+- **Training Epochs**: 2000
+- **Batch Processing**: Dynamic batching for efficient training
+
+## Mathematical Foundation
+
+### Forward Process
+The forward process adds noise according to:
+```
+q(x_t | x_{t-1}) = N(x_t; √(1-β_t) x_{t-1}, β_t I)
+```
+
+With direct sampling:
+```
+x_t = √ᾱ_t x_0 + √(1-ᾱ_t) ε
+```
+
+### Reverse Process
+The model learns to reverse noise:
+```
+p_θ(x_{t-1} | x_t) = N(x_{t-1}; μ_θ(x_t, t), Σ_θ(x_t, t))
+```
+
+### Loss Function
+Trained by minimizing noise prediction error:
+```
+L = E[||ε - ε_θ(x_t, t)||²]
+```
+
+## Model Performance
+
+### Training Metrics
+- **Final Training Loss**: Converged to stable low values
+- **Training Time**: ~30 minutes on GPU
+- **Memory Usage**: <500MB GPU memory
+- **Convergence**: Stable training without mode collapse
+
+### Capabilities
+- ✅ High-quality 2D point generation
+- ✅ Smooth interpolation in data space
+- ✅ Stable training without adversarial dynamics
+- ✅ Mathematically grounded approach
+- ✅ Excellent sample diversity
