## Overview
11+
12+
![Training Visualization](docs/training_plot.png)
13+
14+
Neural\_Network\_C is an advanced neural network implementation in pure C, optimized for high performance on CPUs and NVIDIA GPUs. It includes features such as:
15+
16+
- **Dynamic network architecture** (user-defined layers and neurons)
17+
- **GPU Optimization** (CUDA, cuBLAS, cuDNN, Tensor Cores support)
18+
- **Advanced optimization techniques** (Adam, RMSprop, NAG, Dropout, BatchNorm, L2 Regularization)
19+
- **Convolutional Layers & Attention Mechanisms** (CNNs, Self-Attention, Transformer Layers)
20+
- **RNNs & LSTMs** (GRUs, Bi-Directional LSTMs)
21+
- **Parallelization & Distributed Training** (OpenMP, multi-threading, CUDA Multi-GPU, MPI for clusters)
22+
- **Federated Learning** (Decentralized model training across multiple clients)
23+
- **Dataset loader & preprocessing** (MNIST, CIFAR-10, OpenCV for image augmentation, HDF5 support)
24+
- **Compiler & CPU Optimizations** (AVX/SIMD, memory pooling, thread pools)
25+
- **Mixed-Precision Training** (FP16 optimization for faster prformance)
26+
- **Real-Time Monitoring** (TensorBoard alternative for tracking metrics)
27+
- **Bayesian Hyperparameter Optimization** (Automated hyperparameter tuning)
28+
- **Model Quantization** (Faster inference by reducing precision)
29+
30+
## Requirements
31+

37+
- NVIDIA CUDA Toolkit (for GPU acceleration)
38+
- cuDNN (for optimized deep learning operations)
39+
- OpenMP (for multi-threading support)
40+
- MPI (for distributed training)
41+
- OpenCV (for dataset preprocessing & augmentation)
42+
- HDF5 (for dataset storage & retrieval)
43+
- Python3 (for graph visualization with Matplotlib)
44+
- TensorBoard Logger (for real-time metric tracking)
45+
46+
### Installation:
47+
48+
```sh
49+
sudo apt update && sudo apt install -y build-essential cmake libopencv-dev hdf5-tools python3-pip
50+
pip3 install matplotlib json-c tensorboard_logger
51+
```
52+
53+
## Compilation
54+
55+
To compile the project, use:
56+
57+
```sh
58+
make all
59+
```
60+
61+
Or manually:
62+
63+
```sh
64+
gcc -o neural_network main.c -lm -fopenmp -O3 -march=native -ljson-c -lhdf5 -I/usr/local/cuda/include -L/usr/local/cuda/lib64 -lcudart -lcublas -lcudnn
65+
```
66+
67+
## Running the Project
68+
69+
To train the model:
70+
71+
```sh
72+
./neural_network
73+
```
74+
75+
To run on multiple GPUs:
76+
77+
```sh
78+
mpirun -np 4 ./neural_network
79+
```
80+
81+
## Features in Detail
82+
83+
### 1. **Federated Learning**
84+
85+
The model is trained across multiple clients, preserving data privacy by exchanging only gradients instead of raw data.
86+
87+
### 2. **Transformer Layers**
88+
89+
Implements multi-head self-attention and position-wise feed-forward networks for improved sequence learning.
90+
91+
### 3. **Dataset Augmentation**
92+
93+
Using OpenCV, images are augmented with flipping, rotation, and blurring to enhance generalization.
94+
95+
### 4. **Mixed-Precision Training**
96+
97+
FP16 computation speeds up training using Tensor Cores.
98+
99+
### 5. **Quantization**
100+
101+
Weights are quantized to reduce model size and increase inference speed.
102+
103+
### 6. **Bayesian Hyperparameter Optimization**
104+
105+
Automatically fine-tunes learning rates for optimal convergence.
106+
107+
## Output & Graph Visualization
108+
109+
After training, the results are saved in `training_plot.png`, displaying loss and accuracy progress.
110+
To manually generate the graph:
111+
112+
```sh
113+
python3 training_plot.py
114+
```
