Hello, everyone! My name is Hamish Leahy, and today I am excited to share with you my journey through the process of creating my very first neat neural network. As a passionate technology enthusiast, delving into the realm of artificial intelligence and machine learning has always been a dream of mine. It was a challenging yet rewarding experience that taught me valuable lessons, and I am thrilled to take you along on this adventure.


The idea of creating my own neural network started with a spark of curiosity. I had been fascinated by the advancements in AI and its applications in various fields. The prospect of building my own intelligent system, capable of learning from data, intrigued me. So, I decided to embark on this journey with no prior experience in neural networks but armed with an unyielding enthusiasm to learn.


My first step was to immerse myself in the basics of neural networks. I began by reading online tutorials and textbooks that provided a solid foundation in machine learning concepts, linear algebra, and calculus. Understanding the math behind neural networks was vital to grasp the underlying principles and develop a solid intuition for the algorithms involved.


The world of machine learning frameworks can be overwhelming, with various options available. After some research, I decided to use the Python library Neat, an abbreviation for "NeuroEvolution of Augmenting Topologies." Its simplicity and ease of use made it an excellent starting point for my journey.


Before diving into the coding process, I outlined my goals for the project. I wanted to build a neural network that could learn from input data and classify it into different categories accurately. My aim was to start with a simple task and gradually expand the network's complexity as my understanding deepened.


With my goals set, I needed a dataset to train and test my neural network. I chose a popular dataset for image classification, the MNIST dataset, which consists of hand-drawn digits from 0 to 9. After obtaining the data, I carefully preprocessed it, scaling the pixel values between 0 and 1 and dividing it into training and testing sets.


Now came the exciting part—designing the neural network architecture! Neat uses a genetic algorithm to evolve the network's structure, allowing it to adapt and improve automatically. I experimented with different configurations, adjusting the number of layers, neurons, and activation functions to optimize the performance.


Once the architecture was set, I commenced the training process. This involved passing the training data through the network, measuring its performance, and adjusting the weights and biases using the genetic algorithm. I closely monitored the training progress, ensuring the network was learning and making improvements over time.


Throughout this journey, I encountered several challenges. Debugging errors, fine-tuning parameters, and understanding the genetic algorithm took time and effort. However, each obstacle provided invaluable lessons, teaching me the importance of perseverance, patience, and continuous learning.


After several iterations and late-night coding sessions, I achieved a well-trained neural network. Watching it accurately classify handwritten digits filled me with a sense of accomplishment and excitement. The joy of seeing my creation in action made all the hard work worthwhile.


My journey through creating my first neat neural network was an incredible experience. It opened my eyes to the vast possibilities of AI and machine learning. Building a neural network from scratch taught me not only technical skills but also the importance of curiosity, determination, and problem-solving.

I encourage anyone interested in machine learning to embark on a similar journey. The AI field is constantly evolving, and there is always something new to learn and explore. Remember, the key is to start small, take it step-by-step, and be unafraid of making mistakes.

Thank you for joining me on this adventure, and I hope my story inspires you to begin your own journey into the fascinating world of neural networks. Happy coding and happy learning!
