Fraud detection: You get a call from your credit card company asking whether you made a particular purchase. The credit card company isn’t being nosy; it’s simply alerting you to the fact that someone else could be making a purchase using your card. The AI embedded within the credit card company’s code detected an unfamiliar spending pattern and alerted someone to it.
Resource scheduling: Many organizations need to schedule the use of resources efficiently. For example, a hospital may have to determine where to put a patient based on the patient’s needs, availability of skilled experts, and the amount of time the doctor expects the patient to be in the hospital.
Complex analysis: Humans often need help with complex analysis because there are literally too many factors to consider. For example, the same set of symptoms could indicate more than one problem. A doctor or other expert might need help making a diagnosis in a timely manner to save a patient’s life.
Automation: Any form of automation can benefit from the addition of AI to handle unexpected changes or events. A problem with some types of automation today is that an unexpected event, such as an object in the wrong place, can actually cause the automation to stop. Adding AI to the automation can allow the automation to handle unexpected events and continue as if nothing happened.
Customer service: The customer service line you call today may not even have a human behind it. The automation is good enough to follow scripts and use various resources to handle the vast majority of your questions. With good voice inflection (provided by AI as well), you may not even be able to tell that you’re talking with a computer.
Safety systems: Many of the safety systems found in machines of various sorts today rely on AI to take over the vehicle in a time of crisis. For example, many automatic braking systems rely on AI to stop the car based on all the inputs that a vehicle can provide, such as the direction of a skid.
Machine efficiency: AI can help control a machine in such a manner as to obtain maximum efficiency. The AI controls the use of resources so that the system doesn’t overshoot speed or other goals. Every ounce of power is used precisely as needed to provide the desired services.
This list doesn’t even begin to scratch the surface. You can find AI used in many other ways. However, it’s also useful to view uses of machine learning outside the normal realm that many consider the domain of AI. Here are a few uses for machine learning that you might not associate with an AI:
Access control: In many cases, access control is a yes or no proposition. An employee smartcard grants access to a resource much in the same way that people have used keys for centuries. Some locks do offer the capability to set times and dates that access is allowed, but the coarse-grained control doesn’t really answer every need. By using machine learning, you can determine whether an employee should gain access to a resource based on role and need. For example, an employee can gain access to a training room when the training reflects an employee role.
Animal protection: The ocean might seem large enough to allow animals and ships to cohabitate without problem. Unfortunately, many animals get hit by ships each year. A machine learning algorithm could allow ships to avoid animals by learning the sounds and characteristics of both the animal and the ship.
Predicting wait times: Most people don’t like waiting when they have no idea of how long the wait will be. Machine learning allows an application to determine waiting times based on staffing levels, staffing load, complexity of the problems the staff is trying to solve, availability of resources, and so on.
Being useful; being mundane
Even though the movies make it sound like AI is going to make a huge splash, and you do sometimes see some incredible uses for AI in real life, the fact of the matter is that most uses for AI are mundane, even boring. For example, a recent article details how Verizon uses the R language to analyze security breach data (https://www.computerworld.com/article/3001832/data-analytics/how-verizon-analyzes-security-breach-data-with-r.html
and https://softwarestrategiesblog.com/category/verizons-2020-data-breach-investigations-report-dbir/
). Part 5 of this book provides you with real-world examples of this same sort of analysis. The act of performing this analysis is dull when compared to other sorts of AI activities, but the benefits are that Verizon saves money performing the analysis using R, and the results are better as well.
In addition, Python developers (see Chapters 4 and 5 for Python language details) have a huge array of libraries available to make machine learning easy. In fact, Kaggle (https://www.kaggle.com/competitions
) provides competitions to allow Python developers and R practitioners to hone their machine learning skills in creating practical applications. The results of these competitions often appear later as part of products that people actually use. Although R still relies on strong support from the statistical community in academic research, the Python development community is particularly busy creating new libraries to make development of complex data science and machine learning applications easier (see https://www.globalsqa.com/top-20-open-source-python-libraries/
for the top 20 Python libraries in use today).
Considering the Relationship between AI and Machine Learning
Machine learning is only part of what a system requires to become an AI. The machine learning portion of the picture enables an AI to perform these tasks:
Adapt to new circumstances that the original developer didn’t envision
Detect patterns in all sorts of data sources
Create new behaviors based on the recognized patterns
Make decisions based on the success or failure of these behaviors
The use of algorithms to manipulate data is the centerpiece of machine learning. To prove successful, a machine learning session must use an appropriate algorithm to achieve a desired result. In addition, the data must lend itself to analysis using the desired algorithm, or it requires a careful preparation by scientists.
AI encompasses many other disciplines to simulate the thought process successfully. In addition to machine learning, AI normally includes
Natural language processing: The act of allowing language input and putting it into a form that a computer can use.
