Context
Training is at the heart of Artificial Intelligence: it is the process by which models learn from data and improve their predictive capabilities. In this article, we explore the steps, techniques, and best practices for effective AI training, ensuring reliable and high-performance results.
What is Artificial Intelligence training?
Main Stages of Training
Data collection and preparation
- Collection: The first step is to obtain high-quality data that is relevant to the problem being solved.
- Cleaning and Preprocessing: Data is filtered and normalized to eliminate noise and inconsistencies, ensuring that the model can learn effectively.
Training and optimization
- Training: During this phase, the model is fed with data and its parameters are updated based on the error made in the predictions.
- Hyperparameter Tuning: A crucial step in which you adjust key variables, such as the learning rate, to optimize the performance of the model.
Validation and testing
- Cross-Validation: Cross-validation techniques are used to verify the model’s ability to generalize to unseen data.
- Test and Evaluation: The model is tested on a separate dataset to measure its accuracy, precision, and robustness.
Training techniques and methodologies
Supervised learning
Unsupervised learning
Reinforced learning
Hybrid approach to training
When it comes to training advanced artificial intelligences such as Large Language Models (LLMs), it is important to understand that a single learning paradigm is rarely used in isolation. Often, the key to achieving high-performance and versatile models lies in a hybrid approach, which combines the strengths of different techniques.
Let’s take Gemini, the model developed by Google, as a concrete example. Its impressive ability to understand and generate text, images, audio, video and code is not the result of a single type of training, but of a skilful orchestration of different methodologies

Best practices in AI training
Data Quality:
Investing in the collection of accurate and representative data is critical to effective training.
Continuous Monitoring:
Continuously evaluate model performance to identify overfitting or underfitting issues and make adjustments as needed.
Security and Privacy:
Protect sensitive data using anonymization techniques and ensuring compliance with privacy regulations throughout the training process.
Iteration and Update:
Training is not a static process ā it is important to review and update models regularly to adapt to market changes and new information.
