Training data for AI: 5 keys to developing reliable models

The world of artificial intelligence (AI) is evolving at a rapid pace and with it, the expectations of businesses. As AI becomes increasingly integrated into various industries, executives and managers are looking for ways to ensure that their organizations stay ahead of the curve. One crucial component in developing accurate AI models is training data for AI reliability – the backbone on which these intelligent systems operate. In this blog post, we will explore why training data is essential for creating accurate and effective AI models, how to source high-quality training data, and best practices for utilizing it in your organization’s AI strategy.

Today, training data is essential for the success of any artificial intelligence model or project. However, it must be organized and structured for easy use in our systems or applications. Without quality data and good data preparation, it is impossible to achieve this goal. We will guide you through the best recommendations for working with training data.

AI relies on large amounts of data. Machine learning (ML) algorithms learn to find correlations and patterns between data sets and apply these learnings to any new data presented to them. So the greater the volume and quality of the data (consistent, diverse, complete, and relevant), the more accurate the algorithms will be.

So what is the role of “training data” in this process? Training data is “labeled” data that is used to teach artificial intelligence models or machine learning algorithms to make appropriate decisions based on different contexts.

Using the example of a chatbot or virtual assistant, if we were trying to create a similar customer service tool that was available 24 hours a day, the data could include all the different ways to ask: What is the next available shift? How can I find a store near my home? Both in text and audio, with the appropriate phrase translated into different languages.

Training data is critical to the success of any AI model, but it must be organized in a way that is easy for AI systems to use. Without quality training data, you can’t get anywhere. We may have the most appropriate and advanced algorithm, but if we train our machines with bad or biased data, they will learn the wrong lessons, fail to meet expectations, and not perform as expected. Therefore, the success of an AI project depends almost entirely on data.

Types of data for AI

Data is used at all stages of the AI development process and can be broadly categorized as follows

  1. Training data: data used to train the AI model.
  2. Test data: data used to test the model and compare it to other models.
  3. Validation data: data used to validate the final AI model.

Training data can be structured or unstructured; an example of the former is the market data presented in tables, and an example of the latter is the audio, video, and image files.

Data Sources for reliable AI models

Where can you get training data? It can be obtained internally, such as from customer data held by organizations, or externally, from third-party sources.

Internal data is often used for AI training, or more specifically, for internal projects. Examples include Spotify’s AI DJ, which tracks your listening history to generate playlists, and Meta (Facebook, Instagram, and WhatsApp), which runs its users’ data through its recommendation algorithm to drive recommended content.

At the same time, data can be extracted from large vendors that buy and sell large amounts of data, or from public databases such as Amazon’s. Other external data sources include open data sets, such as those provided by governments, research institutions, and, in general, companies for commercial purposes.

It is important that in the process of extracting data, we do not violate any regulations or copyrights regarding the ownership of the data. All of these practices are governed by compliance regulations and ethical standards.

Best practices: Quantity, Quality and Preparation of the Data

An additional factor of training data has to do with its quantitative aspect. In general, the more training data we have, the better the final result will be. However, it is important to note that not only the quantity of data is important, but also its quality. A well-curated and labeled training data set can be more effective than a much larger but lower quality data set.

Furthermore, one of the main challenges in using training data is its collection and preparation. Collecting high-quality data can be time-consuming and resource-intensive, especially if the problem you are trying to solve is complex or has not been studied before.

It is usually necessary to manually annotate the training data, adding tags or metadata that correctly describe each example. This process can be tedious and in most cases requires human intervention. Once the training data has been collected and properly prepared, the model training phase can proceed, yielding a reliable result that is usually of very high quality.

Training Data for AI – Key Recommendations:

  1. Understand both the problem and the goals of the AI/ML project early on.
  2. Collect and evaluate accurate data to ensure quality and relevance.
  3. Use properly labeled data and metadata.
  4. Start training with a small data set, then test and scale.
  5. Have enough data (the more data, the higher the accuracy).
