The human interface

For those of you old enough, or unfortunate enough, to have used early versions of the Microsoft office suite, you will probably remember the Mr Clippy office assistant. This feature, first introduced in Office 97, popped up uninvited from the bottom right-hand side of your computer screen every time you typed the word 'Dear' at the beginning of a document, with the prompt "it looks like you are writing a letter, would you like help with that?".

Mr Clippy, turned on by default in early versions of Office, was almost universally derided by users of the software and could go down in history as one of machine learning's first big fails.

So, why was the cheery Mr Clippy so hated? Clearly the folks at Microsoft, at the forefront of consumer software development, were not stupid, and the idea that an automated assistant could help with day to day office tasks is not necessarily a bad idea. Indeed, later incarnations of automated assistants, the best ones at least, operate seamlessly in the background and provide a demonstrable increase in work efficiency. Consider predictive text. There are many examples, some very funny, of where predictive text has gone spectacularly wrong, but in the majority of cases where it doesn't fail, it goes unnoticed. It just becomes part of our normal work flow.

At this point, we need a distinction between error and failure. Mr Clippy failed because it was obtrusive and poorly designed, not necessarily because it was in error; that is, it could make the right suggestion, but chances are you already know that you are writing a letter. Predictive text has a high error rate, that is, it often gets the prediction wrong, but it does not fail largely because of the way it is designed to fail: unobtrusively.

The design of any system that has a tightly coupled human interface, to use systems engineering speak, is difficult. Human behavior, like the natural world in general, is not something we can always predict. Expression recognition systems, natural language processing, and gesture recognition technology, amongst other things, all open up new ways of human-machine interaction, and this has important applications for the machine learning specialist.

Whenever we are designing a system that requires human input, we need to anticipate the possible ways, not just the intended ways, a human will interact with the system. In essence, what we are trying to do with these systems is to instil in them some understanding of the broad panorama of human experience.

Thinking in Machine Learning

Machine learning systems have a profound and exciting ability to provide important insights to an amazing variety of applications; from groundbreaking and life-saving medical research, to discovering fundamental physical aspects of our universe. From providing us with better, cleaner food, to web analytics and economic modeling. In fact, there are hardly any areas of our lives that have not been touched by this technology in some way. With an expanding Internet of Things, there is a staggering amount of data being generated, and it is clear that intelligent systems are changing societies in quite dramatic ways. With open source tools, such as those provided by Python and its libraries, and the increasing open source knowledge base represented by the Web, it is relatively easy and cheap to learn and apply this technology in new and exciting ways. In this chapter, we will cover the following topics.

• Human interface • Design principles • Models • Unified modelling language
