# 🧠 RNN in C
This is a simple implementation of a **Recurrent Neural Network (RNN)** in **pure C**.
It demonstrates the concept of forward propagation over a sequence of time-series inputs without using any external libraries.

---
## 🧪 Requirements
- GCC or compatible C compiler (e.g. `gcc`, `clang`)
- `make` (for building the project)
---
## ⚙️ Build Instructions
### 1. Clone or download the project:
```bash
git clone https://github.com/nomadsdev/rnn-model-with-c.git
cd rnn-c
```
### 2. Build the project using `make`:
```bash
make
```
This compiles all `.c` files and generates an executable named `rnn`.
---
## 🚀 Running the Program
```bash
./rnn
```
### Expected Output:
```text
Time step 0: Output: 0.4938
Time step 1: Output: 0.4962
Time step 2: Output: 0.4975
```
The program performs forward propagation across 3 time steps using a hardcoded input sequence (`0.1`, `0.5`, `0.9`) and prints the output of the RNN at each step.
---
## 🧰 How to Modify Inputs
To change the input sequence:
1. Open `main.c`
2. Modify the `inputs[]` array:
```c
float inputs[] = {0.2f, 0.4f, 0.6f, 0.8f};
```
3. Rebuild the project:
```bash
make clean && make
./rnn
```

## 🛠️ How to Extend This Project
Here are some ideas for improving this base project:
- ✅ Add Backpropagation Through Time (BPTT)
- 📉 Loss function and training loop
- 📁 Load input from file (`sample_input.txt`)
- 🧠 Increase model complexity (e.g., stacked RNN layers)
- 💾 Save and load weights to/from file
