Definition
AI training data
is a collection of information, or inputs, used to train AI models to give
accurate predictions or decisions. For example, if a model is being taught to recognize
images of dogs, its AI training dataset will be made up of pictures containing
dogs, with each dog labelled 'dog'. This data is inputted into the AI model as
learning inputs, eventually enabling it to recognize dogs accurately in other,
previously unseen images [1].
Training data in Machine Learning [2]
Origin
There are interesting cycles in the history of training data. In the 1990’s, before Machine Learning dominated AI, programmers hard-coded rules to improve the performance of their systems, based on the behavior of their models. When Machine Learning came to dominate almost 20 years later, we returned to similar Human-in-the-Loop systems, but with non-expert human annotators creating the training data based on model behavior [3].
Context and Usage
Training data is used in the field of AI and machine learning. Training data is fed into an ML model, where algorithms examine it to discover patterns. This allows the ML model to give more accurate predictions or classifications on future, similar data [4]. Many industries are leveraging AI training data, including healthcare, finance, manufacturing, retail, and transportation, to improve processes, enhance decision-making, and gain a competitive edge.
Why it Matters
The quality and quantity of a collection of training data is key to the accuracy and effectiveness of machine learning models. The more diverse and representative the data is, the better the model can generalize and perform on new, unseen data. Conversely, biased or incomplete training data can lead to incorrect or unfair predictions [5].
Related Terms
- Labeled Data: Data where each input is paired with a known output, used in supervised learning.
- Supervised Learning: A type of machine learning where the model is trained on labeled data.
- Unsupervised Learning: A type of machine learning where the model is trained on unlabeled data.
In Practice
A real-life case
study of a company practicing training data in AI can be seen in the case of Zindi,
an African data science platform that works with many Nigerian and African
researchers and companies. Zindi provides AI training data through its
competitions and challenges, offering datasets for various AI projects, and
also offers courses and resources to help users learn and improve their skills
in data science and AI. This approach allows African data scientists and
researchers to create AI solutions tailored to local African challenges by
using locally sourced, contextually relevant training data.
