Training Machine Learning Models

June 23, 2023

In today's Blog post, we plan to demystify the process of training machine learning models, likening it to teaching a new skill to a human and understanding its significance for your business.

What is a Machine Learning Model?

Before discussing how to train a machine learning model, we must start by understanding it. A machine learning model, in simple terms, is a type of computer program that learns from data to make predictions or decisions. Instead of being explicitly programmed to carry out a specific task, a machine learning model is trained on a large amount of data, learning patterns and information from that data. Once trained, the model can apply what it learned to new, unseen problems. This ability to learn from data and make predictions makes machine learning a powerful tool in many areas, including image recognition, natural language processing, and recommendation systems. Groundbreaking examples of this technology include ChatGPT, which uses machine learning to generate human-like text responses, and self-driving cars, which use machine learning to navigate roads and traffic safely and efficiently.

The Essence of Training

In this blog, we will utilize the sport of golf as a metaphor to illustrate the process of training machine learning models. Imagine you're teaching someone to play golf. You'd start by explaining the rules, demonstrating the techniques, and then letting them practice until the improve. Training a machine learning model is somewhat similar, but instead of golf, it might be learning to predict stock prices, recognize customer sentiments, or detect fraud.

In machine learning, training refers to teaching an algorithm to make predictions or decisions based on data. Much like teaching golf, you provide the model with examples (data), explain the outcomes you desire (labels), and let it practice and learn the underlying patterns. And it can even provide a mathematical assessment of its learning progress.

The Ingredients for Training

1. Data: The Practice Ground

Data is like the practice ground for the model. The more varied and representative the data, the better the model can learn. Imagine trying to become a golf pro by only practicing putts; that wouldn't be very effective. Similarly, a machine learning model needs diverse data to learn effectively.

2. Algorithm: The Learning Technique

The algorithm is like the teaching method or the set of rules the model will use to learn from the data. This might be the grip, stance, or swing technique in golf. In machine learning, algorithms range from decision trees to neural networks, each with strengths and weaknesses depending on the problem.

3. Feedback: The Coach's Advice

In business, we all understand the importance of feedback. In machine learning, the model gets feedback through a loss function. It's like a coach telling the player how far off their shot was. The model uses this feedback to adjust and improve.

Specialized Training: Enter Neural Networks

One of the more advanced algorithms is the neural network. Imagine a team where each player specializes in a specific game aspect. Each "player" is called a neuron in a neural network, and they work together to make predictions. The more players (neurons), the more complex patterns it can learn.

Among neural networks, Transformers are the top players. They're especially good at handling sequential data, like time series or natural language. They pay attention to different parts of the data and can weigh the importance of different pieces of information. This makes them extremely powerful for tasks like language translation or stock prediction.

The Finish Line: A Well-Trained Model

After training, you have a model ready to make prediction on new, unseen data. It's like having a trained golf player prepared to compete. Now that you know how to train a model, take a look at all the kinds of models you can create here:
