Examples of Machine Learning (ML)

In a newsletter I discuss how machine learning developed as a way to overcome certain limitations in the early days of artificial intelligence. Without machine learning, machines would be able to do only what they were told or were programmed to do. Machine learning expands their capabilities beyond what they were merely programmed to do.

As shown below, here are examples of machine learning applications across a wide variety of fields ranging from data security and software development to investing and healthcare.

One of the best ways to understand machine learning is to look at the various applications of machine learning in the real world:

• Data security: Malware (viruses, worms, etc.) is constantly evolving to avoid detection, but changes to malware code typically constitute only about two to ten percent of code; the rest of the code remains unchanged. With machine learning, security software can identify patterns in the code and distinguish what has changed from what hasn't. This enables the software to identify new versions of malware. Machine learning is also useful for detecting early warning signs of infection from unknown malware, such as an unexplained drop in available system resources.
• Investing: Machine learning algorithms drive about 70 percent of all trading volume on the U.S. stock exchanges. With machine learning, computers can process vast amounts of financial data and quickly analyze stocks, bonds, trading trends, and other information to identify which investments have the greatest potential for positive returns. Computers are also capable of executing trades faster than humanly possible, which may provide investors with another advantage.
• Online software development: Software developers can use machine learning to create software that automatically adapts to user behaviors. For example, as someone who plays an online game becomes more skilled, the game can make itself more challenging. Developers can also use machine learning to identify ideas for new features and new ways to monetize the software.
• Healthcare: It is highly unlikely that machines will replace doctors anytime soon, but machine learning has become a valuable tool in the healthcare field. Machine learning can identify patterns in medical images or symptoms to improve the accuracy of diagnoses and treatments. Machines may also be better at reviewing the medications a patient is taking and alerting the patient or pharmacist of possible drug interactions.
• Personalized marketing: Companies have been using machine learning for some time to market their products and services to consumers. For example, Google and Amazon keep track of your search and purchase history in order to make targeted product recommendations. Netflix and Spotify use machine learning to recommend movies and music based on your viewing or listening history.
• Fraud detection and prevention: Credit card companies keep track of where cardholders use their cards, what they buy, the average transaction amount, and more. These companies then use machine learning algorithms to identify any transactions that break the cardholder's usage patterns. Any suspicious activity triggers a fraud alert and possibly an automatic suspension of the account. The cardholder may then be required to call the credit card company to have the suspension lifted.
• Online searches: Google, Bing, Yahoo!, and other search engines use machine learning to rank items in their search results, which is why search results typically differ based on several factors, including your browser's search history, your current geographical location, and the relevance of various websites to the search word or phrase. If you use your smartphone to search for "grocery store," for example, you're likely to be presented a list of grocery stores in your general vicinity.
• Smart devices: Smart devices collect data regarding their usage, then personalize their operation based on those patterns. For example, a smart home may learn that whenever you unlock the front door at a certain time in the evening, it means you have returned home from work. The smart lock then signals the smart thermostat to adjust the temperature accordingly. Smart devices may even use facial recognition technology and security cameras to identify a home's residents and then warn the homeowner (or notify police) if someone other than a resident approaches or enters the home at certain times.
• Self-driving cars: Self-driving cars have made the transition from science fiction to the real world. By combining machine learning, video, GPS, robotics, and a host of other technologies, cars can now drive themselves, although some mishaps have occurred.

Final Thoughts On Machine Learning (Ml)

These are only a few of the vast number of machine learning applications that are possible. As machine learning matures, you are likely to see many more real-world applications and consumer products and services driven by machine learning.

Frequently Asked Questions

What are some real-life examples of AI and machine learning in day-to-day life?

Real-life machine learning examples include:

• Recommendation systems on streaming services Spam email filtering
• Predictive text on smartphones
• Facial recognition features in photo apps

These use various machine learning techniques such as supervised and unsupervised learning.

How is machine learning used in image recognition or Facial recognition?

Machine learning, particularly deep learning and neural networks, is extensively used in image recognition.

By training on large datasets of labeled images, these models can learn to identify and classify objects, faces, and scenes, powering features like automated photo tagging and security surveillance systems.

What role does supervised learning play in predictive analytics?

Supervised learning is crucial for predictive analytics, involving training a machine learning model on known input (training data) and output pairs.

This allows the model to make predictions on new, unseen data. Common applications include customer behavior forecasting and credit scoring.

What examples showcase the use of unsupervised machine learning basics?

Unsupervised learning is useful for grouping and interpreting data without pre-existing labels.

Examples include:

• Market basket analysis in retail (clustering products often bought together)
• Customer segmentation
• Anomaly detection in network security.

How are neural networks applied in natural language processing (NLP)?

Neural networks, particularly recurrent neural networks (RNNs) and transformers, are applied in NLP for tasks such as machine translation, text summarization, sentiment analysis, and language modeling.

These systems learn language patterns from vast amounts of input data.

What are the benefits of semi-supervised learning in machine learning applications?

Semi-supervised learning leverages a small amount of labeled data combined with a large amount of unlabeled data.

This approach is beneficial in applications like image recognition and text classification where obtaining labeled data is expensive or time-consuming, improving the model's performance without extensive annotation.

How are machine learning models trained for product recommendations?

Machine learning models for product recommendations are typically trained using supervised learning on large datasets containing user behavior and item attributes.

They analyze patterns in past user interactions to predict and suggest products that a user is likely to be interested in.

What is the significance of training data in constructing a machine learning system?

Training data is essential for constructing a machine learning system as it provides the examples from which the model learns.

Quality and quantity of training data directly affect the model's accuracy and generalization ability. Proper preparation and preprocessing of training data are therefore critical steps in the machine learning workflow.

How do different types of machine learning models contribute to data analysis?

Different types of machine learning models, such as classification, regression, clustering, and reinforcement learning models, contribute to various aspects of data analysis.

Classification models help categorize data, regression models predict numerical outcomes, clustering models group similar data points, and reinforcement learning models optimize decision-making processes based on feedback.

This is my weekly newsletter that I call The Deep End because I want to go deeper than results you’ll see from searches or LLMs. Each week I’ll go deep to explain a topic that’s relevant to people who work with technology. I’ll be posting about artificial intelligence, data science, and data ethics.

This newsletter is 100% human written 💪 (* aside from a quick run through grammar and spell check).
