The more I learn about machine learning the more fascinated I am by it. At Iteracy we've recently started using a system called Generative Pre-trained Transformer 3 (GPT-3) to help clients analyse and write natural language documents.
I asked OpenAi's GPT-3 tool to write me a post entitled What Is Machine Learning? The rest of this article was written entirely by that system and then mildly edited by me for clarity, to reduce some repetitions, and to change the spelling to British English.
I'm astonished by how natural the text feels. Can you tell it was written by a computer?

What is machine learning?

Machine learning is a type of artificial intelligence that enables computers to learn from data without being explicitly programmed. Machine learning algorithms can automatically improve with experience, making them increasingly accurate in predicting outcomes. This is in contrast to traditional computer programs, which must be explicitly programmed by humans with a specific task in mind.
It has a number of applications, including:
  • Fraud detection
  • Speech recognition
  • Predicting consumer behaviour
  • Image recognition
  • Autonomous vehicles

How does it work?

Machine learning involves using algorithms to parse data, identify patterns and trends, and then learn from the results. This can be used to improve the performance of a computer system or to enable it to make decisions on its own.
Machine learning algorithms have a number of benefits over traditional methods, including:
  • Flexibility: they are able to adapt as they receive more data.
  • Accuracy: they are able to find patterns in data that traditional methods may not be able to detect.
  • Efficiency: they are able to analyze data more quickly than traditional methods.

Example applications

User retention

One of the most important aspects of any business is retaining users. It can be costly to acquire new users, so it's important to make sure you're doing everything you can to keep the ones you have. Machine learning can be used to help with user retention by predicting which users are most likely to leave and then taking action to try to keep them. This could involve sending them a notification or email, offering them a discount, or suggesting a particular action they can take to stay engaged.

Predicting customer behaviour

Machine learning can also be used to predict customer behaviour. This can be used to help businesses understand what customers are likely to do in the future, such as buying a particular product or service. This can be used to help businesses plan their marketing and product development efforts, as well as to understand how customers are likely to respond to changes in the business.


One application in healthcare is to improve the accuracy of diagnoses. Machine learning can be used to improve the accuracy of diagnoses by identifying patterns in medical data that are not obvious to human doctors, for example to identify patterns in medical data that are associated with specific diseases. This can help doctors to diagnose diseases more accurately.
Machine learning can also be used to improve the accuracy of predicting the likelihood of a patient developing a disease in the future. This can help doctors to make more accurate predictions about a patient’s health and to provide them with the appropriate treatments.
Finally, machine learning can be used to improve the efficiency of healthcare services, for example to recommend the best time to book an appointment at a doctor’s office. This can help to reduce the waiting time for appointments.


One of the most important areas of manufacturing is quality control, where there are a large number of variables that can affect the quality of the end product.
Machine learning can be used to analyse the data from the production process and identify patterns that could indicate a problem with the quality of the product. This can help to ensure that the products that are produced are of the highest quality.


There is a lot of potential for machine learning in transportation, such as improving traffic flow and reducing congestion. Another potential application is to predict when a vehicle is likely to need maintenance, to improve vehicle reliability.

The challenges of machine learning

When you think about it, there are a few key challenges that machine learning algorithms face when it comes to accurately learning from data:
  • There can be a lot of data to process. This can include a high number of features or variables, and a large number of training examples.
  • The data can be noisy. This means that it can be difficult to distinguish between signal (important information) and noise (unimportant information).
  • The data can be incomplete. This means that not all of the information needed to learn a task may be available.
  • The task itself may be difficult to learn. This could be because it is complex, or because the training data is limited.
Despite these challenges, machine learning algorithms have been shown to be effective in a wide range of tasks, from recognizing objects in images, to understanding natural language, to predicting consumer behaviour.

The future of machine learning

The future of machine learning is exciting because it has the potential to make many tasks easier and faster. Additionally, machine learning may be able to help us better understand complex systems and make better decisions.
