What is AI Training Data? Explore AI Training Datasets & Providers

AI Training Data Explained

AI training data refers to the labeled information used to train artificial intelligence and machine learning models. Examples of AI training data include labeled images, text documents, audio recordings, and sensor data. This data is used to teach AI systems to recognize patterns, make predictions, and perform various tasks. In this page, you will find the best AI training data and datasets, including Textual Data, Machine Learning (ML) Data, Deep Learning (DL) Data, Annotated Imagery Data, Synthetic Data, Audio Data, and Large Language Model (LLM) Data.

AI Training Data Attributes

Training data has many forms and attributes, reflecting the numerous potential applications of machine learning algorithms. AI training datasets can include text consisting of both words and numbers, audio, images, and video. Moreover, they’re available in many formats, such as PDF, HTML, JSON, or spreadsheets.

The ability to link unstructured and structured data is where the value lies; you get new insights and reveal unknowns.

Broadly speaking, AI training data can be assigned to the following categories:

AI training data can be structured , which means that it’s found in a fixed field within a record or file, e.g. data which is contained in relational databases and spreadsheets.

AI training data can also be unstructured , meaning either that it isn’t intended as a predefined data model or that it isn’t organized in a predefined manner.

Hybrid AI training data also exists, which allows you to make use of a blend of supervised and unsupervised learning.

Attributes of AI training data are labeled or annotated using specific techniques which categorize the data into text, image or video. These labels are used and made suitable for computer vision so that the computer being used to programme the AI machine can recognise the data and the outcome the artificial intelligence should arrive at. By ‘computer vision’, we mean that categorical attributes of the AI data must be changed to a numerical format for the machine learning algorithm to work. These attributes of AI training data vary according to how you want to use it, and the APIs available for this intended use.

AI Training Data Sources

Because it’s such a versatile data type, the sources of AI training data are numerous, and they largely depend on the specific use case. There are many sources that provide information to be used for open AI datasets. Many of these public datasets are maintained by enterprise companies, government agencies, or academic institutions. For more niche use cases, it’s worth getting in touch with your prospective AI training data provider directly, if you’re keen to know more about the sources they use.

How to collect AI Training Data

Again, this varies between sources and use cases, but one typical approach used by AI data providers to collect a large amount of data from the web is the deployment of scraping techniques. The raw data is then stored on a server. Artificial intelligence and machine learning data providers offer APIs to their servers, meaning the data can be accessed directly by customers. This means that you can download a data provider’s AI training datasets according to your individual requirements. Synthetic data is also regularly used for AI training. Synthetic data is generated using algorithms as opposed to being collected from real-world events.

How to assess the quality of AI training Data?

Much like other data types, there are things to look out for when purchasing a third-party AI training dataset to ensure that you’re receiving the highest quality information possible. High-quality AI & ML training data is vital for a successful AI and machine learning initiative. It’ll ensure that you produce algorithms that work in real life, and will allow you to mitigate some of the bias inherent in manual data annotations - one of the main reasons companies rely on AI in the first place.

It’s always a good idea to request a sample dataset from your AI data provider before opting for them. When examining this sample, look out for:

Accuracy
The ratio of data to errors. As you’d expect, errors will lead to skewed machine behaviour, so must be avoided!

Completeness
Empty fields. Missing information will leave gaps in your AI machine’s ‘knowledge’.

Precision
How the data is labeled. With precise and detailed the label on a dataset, you can decide exactly how useful it’ll be for your specific needs. Avoid vaguely labeled AI datasets - their training ability is often weak.

Scale
Data coverage. The versatile your dataset, the better coverage it’ll give your programme, meaning it’ll have a more holistic view on the problems it should solve.

Timeliness
Outdated data is harmful for training AI models. For certain industries and use cases in particular, the timeliness of AI data is highly important if you’re to achieve efficient results.

Obviously, when requesting a sample, make sure you specify the intended use case for your data. With so many possibilities for machine learning, you’ve got to be sure that your provider can give you data that’s relevant to your AI initiative! Remember - your output will only be as good as the input.

If you can ensure that your data provider upholds each of these quality aspects, then you can expect high quality artificial intelligence and machine learning productivity in return. Apart from requesting an AI data sample, you can carry out quality assessment by looking for verified data vendors and providers, who have undergone accuracy and reliability audits to guarantee you the best results for your machine learning operations.

Once you’ve got access to your AI training data, you can monitor its performance in-flight. An analytical approach to quality assessment will show you where the data is falling short of your desired training strategy:

Gold sets or benchmark: This method helps to measure the accuracy by comparing the annotations to a gold set or vetted example. It also helps to estimate the extent to which the dataset meets the desired benchmark.

Consensus or overlap: This process is common to measure the consistency and agreement amongst a group of data points or datasets. This is done by dividing the total of agreeing data points by the total number of points. If there’s a consensus between your datasets, that’s a good indicator that they’re high-quality.

Use Cases

As we’ve said several times in this article, there are countless use cases for AI training data! Let’s have a look at a few examples which showcase how artificial intelligence and machine learning are boosting operation efficiency for all kinds of businesses and organisations:
