## Overview
Neural is a domain-specific language (DSL) designed for defining, training, debugging, and deploying neural networks. With declarative syntax, cross-framework support, and built-in execution tracing (NeuralDbg), it simplifies deep learning development whether via code, CLI, or a no-code interface.

##  Pain Points Solved

Neural addresses deep learning challenges across **Criticality** (how essential) and **Impact Scope** (how transformative):

| Criticality / Impact | Low Impact                  | Medium Impact                       | High Impact                         |
|----------------------|-----------------------------|-------------------------------------|-------------------------------------|
| **High**             |                             |                                     | - **Shape Mismatches**: Pre-runtime validation stops runtime errors.<br>- **Debugging Complexity**: Real-time tracing & anomaly detection. |
| **Medium**           |                             | - **Steep Learning Curve**: No-code GUI eases onboarding. | - **Framework Switching**: One-flag backend swaps.<br>- **HPO Inconsistency**: Unified tuning across frameworks. |
| **Low**              | - **Boilerplate**: Clean DSL syntax saves time. | - **Model Insight**: FLOPs & diagrams.<br>- **Config Fragmentation**: Centralized setup. |                                     |

### Why It Matters
- **Core Value**: Fix critical blockers like shape errors and debugging woes with game-changing tools.
- **Strategic Edge**: Streamline framework switches and HPO for big wins.
- **User-Friendly**: Lower barriers and enhance workflows with practical features.

## Installation

**Prerequisites**: Python 3.8+, pip

### Option 1: Install from PyPI (Recommended)

```bash
# Install the latest stable version
pip install neural-dsl

# Or specify a version
pip install neural-dsl==0.2.6  # Latest version with enhanced dashboard UI
```

### Option 2: Install from Source

```bash
# Clone the repository
git clone https://github.com/Lemniscate-world/Neural.git
cd Neural

# Create a virtual environment (recommended)
python -m venv venv
source venv/bin/activate  # Linux/macOS
venv\Scripts\activate     # Windows

# Install dependencies
pip install -r requirements.txt
```

## Quick Start

### 1. Define a Model

Create a file named `mnist.neural` with your model definition:

```yaml
network MNISTClassifier {
  input: (28, 28, 1)  # Channels-last format

  layers:
    Conv2D(filters=32, kernel_size=(3,3), activation="relu")
    MaxPooling2D(pool_size=(2,2))
    Flatten()
    Dense(units=128, activation="relu")
    Dropout(rate=0.5)
    Output(units=10, activation="softmax")

  loss: "sparse_categorical_crossentropy"
  optimizer: Adam(learning_rate=0.001)
  metrics: ["accuracy"]

  train {
    epochs: 15
    batch_size: 64
    validation_split: 0.2
  }
}
```

### 2. Run or Compile the Model

```bash
# Generate and run TensorFlow code
neural run mnist.neural --backend tensorflow --output mnist_tf.py

# Or generate and run PyTorch code
neural run mnist.neural --backend pytorch --output mnist_torch.py
```

### 3. Visualize Architecture

```bash
neural visualize mnist.neural --format png
```

This will create visualization files for inspecting the network structure and shape propagation:
- `architecture.png`: Visual representation of your model
- `shape_propagation.html`: Interactive tensor shape flow diagram
- `tensor_flow.html`: Detailed tensor transformations

### 4. Debug with NeuralDbg

```bash
neural debug mnist.neural
```

Open your browser to http://localhost:8050 to monitor execution traces, gradients, and anomalies interactively.

### 5. Use the No-Code Interface

```bash
neural --no_code
```

Open your browser to http://localhost:8051 to build and compile models via a graphical interface.
