Artificial Intelligence vs. Machine Learning: A Deep Dive into Their Applications and Use Cases

With the rapid developments in AI and ML today, the danger of conflating these two is at an all-time high. They are the cornerstone of the innovations of our time, from the simpler implementations like the virtual assistants on our smartphones to the more complex self-driving vehicle algorithms. As much as they are related, the difference is there. Grasping their differences is important for a technology expert, a company executive and even a person who is thinking of taking up a specialized Artificial Intelligence Course or a Machine Learning Course. 

In this article, I will explain the fundamental differences between AI and ML and outline their distinctive applications along with related use cases, so that the impact they have to us in our life can be truly appreciated.

Unpacking the Concepts: AI vs. ML

Artificial Intelligence is the more general, overarching field. It is the science of making machines or systems that perform tasks that typically require human intelligence. These tasks include learning, reasoning, problem-solving, perception, and even language understanding. Consider AI the end-goal—building intelligent agents that operate independently and make decisions.

Machine Learning is a specific and very useful subset of AI. It is a means of creating artificial intelligence. Instead of being programmed a certain way with certain rules for every situation, ML systems are built to learn from data. The more data, the more they improve, over time. This learning capacity is the game changer. It enables machines to determine patterns, predictions, and learn from new data without continually having to be told what to do by humans.

The analogy that can help clarify what we mean by AI/ML is simply this: AI is the umbrella, and ML is a very substantial, high tech tool under the umbrella. You can have AI, and not be able to do ML (e.g. rule-based expert systems), but you can’t have ML without it being an offshoot of AI. For anyone entering a career in this area, understanding this relationship is your first, best step. It is a foundational point made in any respectable artificial intelligence course.

Applications and Use Cases of Artificial Intelligence

There is a wide variety of AI use cases and capabilities that are not limited to predictive modeling. Ultimately, it is about creating a smart solution to help address some of the biggest challenges across the globe. Below we highlight some of the most frequently noted use cases and those being used in real life now.

1. Natural Language Processing (NLP)

NLP is the branch of AI that enables computers to understand, interpret, and generate human language.

• Use Case: Virtual Assistants and Chatbots. Virtual assistants like Siri, Google Assistant, and Amazon Alexa use natural language processing (NLP) to “hear” our command, understand the intent of the user and respond with the appropriate response. Similarly, chatbots on websites utilize NLP to answer customer support cases, process orders, and provide information in spoken form.
• Use Case: Machine Translation. Programs like Google Translate use AI to process the inputs of one language to interpret the syntax and context translating this into an accurate target language.

2. Computer Vision

This area of AI demonstrates the ability for machines to “see” and understand visual inputs from images or video. It is an essential part of a large variety of technologies in use today.

• Use Case: Autonomous vehicles. Self-driving cars or trucks are heavily dependent on computer vision. The system is using real-time video data from cameras to understand the “world” around it; for example, identifying pedestrians, traffic signs, other cars, lane markings all in order to make driving decisions.
• Use Case: Medical imaging analysis. AI systems are learning to analyze medical images like x-rays, MRIs, and CT scans and find subtle patterns that likely indicate something such as cancer, often faster, and better, than a human radiologist.

3. Robotics

AI in robotics is about fashioning robots that can remark their atmosphere, learn from it, and make verdicts to perform tasks.

• Use Case: Manufacturing and Logistics. Occasionally, robots powered by artificial intelligence will do repetitive and precise tasks in factories with tasks such as welding and assembly and even quality control. In logistics, robots operate autonomously in warehouses to refine and transport packages, improving efficiency.
• Use Case: Surgical Robots. In health care, robotic systems relying on AI can help surgeons by offering a steady hand, increased precision, and perform minimally invasive procedures.

Applications and Use Cases of Machine Learning

While AI is the brain, Machine Learning is the learning engine. Machine Learning applications focus on analyzing data, recognizing patterns and making predictions. This is where a good Machine Learning Course is worth its weight in gold, because it’s all about building and training models.

1. Predictive Analytics

This is one of the most mutual and powerful submissions of ML. It involves using numerical algorithms to analyze historical data and forecast future outcomes.

• Use Case: Fraud Detection. Financial entities utilize ML to monitor every transaction in real-time. The models use large data sets from the past when fraudulent activity occurred to find unusual patterns such as a purchase that was unusually large for one individual purchasing or a transaction that occurred in a new area, and flagged as suspected fraud.
• Use Case: Credit Risk Assessment. Banks and lending companies use ML to check the creditworthiness of an applicant for a loan. The algorithm takes into account a person’s financial history of payment and request for loans which were used to ascertain and determine the likelihood of default which aids in deciding the extent to which they play an influential role in a lending decision that is fair lending decisions.

2. Recommendation Engines

These organizations use ML to analyze user behaviour and predilections to suggest products, contented, or services they might like.

• Use Case: E-commerce. When you shop on Amazon and see “Customers who bought this item also bought…” information it is an output of a ML recommendation engine. The recommendation engine looks at all the items you have purchased in the past and what you browsed when you shopped and provides recommendations on related or relevant items, which increases their sales tremendously.
• Use Case: Entertainment. Similarly, streaming sites like Netflix and Spotify utilize complex ML algorithms to suggest movies or shows or music that are based on everything you have viewed or listened to, in addition to similar viewer’s preferences. The recommendations make your experience more personalized and are critical to the user’s ability to stay engaged and return to the site.

3. Spam Filters and Cybersecurity

ML algorithms are repetitively at work in arrears the scenes to protect us from uninvited content and malicious attacks.

• Use Case: Email Spam Filtering. An excellent example of a supervised ML model is your email service’s spam filter. It is trained, using labelled emails indicating spam or not spam (as millions of spam emails are) to learn how to discern junk mail. It is trained to automatically recognize the qualities of spam, such as specific keywords, sender domain(s), and types of attachments to recognize junk mail, and it moves them to a junk mail folder.
• Use Case: Network Security. ML models are also being used to identify anomalies in network traffic for the possibility of a cyber-attack. They learn “normal” behaviour of the network and become aware and can identify relatively quickly, when something abnormal is occurring simply when a large number of login attempts are not normal, or data access is not normal.

The Symbiosis: When AI and ML Work Together

It is important to understand that, in many cases, AI and ML do not exist in privacy; they work collaboratively. A smart home assistant is an excellent example. It has one general goal an intelligent assistant that will respond to your questions, control devices, and manage your schedule which is a defined Artificial Intelligence task. The underlying engine that allows it to recognize your voice and learn your likes/dislikes is Machine Learning.

Similarly, a self-driving car is an artificial intelligence system. The system relies on multiple ML models to accomplish its various tasks, using a computer vision model to recognize objects that are present, a predictive model that forecasts other driver’s actions, and a reinforcement learning model to train itself to be a better driver. The Artificial Intelligence Course that you may take will look at the broad strokes of the overall system, and a Machine Learning Course will teach you how to build and tune the individual components.

Final Thoughts: Choosing Your Path

The difference between AI and ML is more than just a difference in terminology; it represents a distinction in the different levels of complexity in the technology and degree of specialization in terms of careers. Having taken an Artificial Intelligence Course will give you a broad overview of the principles of intelligent systems, while training in a Machine Learning Course will gain you the practical ability, technical skill, and hands-on experience required to build the data-driven models for many of today’s most innovative applications.

There is an increasing demand and need for workers, candidates, professionals, etc., to find and develop talented individuals for roles where both AI and ML are required. Whether intentional or not, fittingly the push towards developing capabilities related to Artificial intelligence and Machine Learning (ML) is turning into an equivalent cultural and technological challenge. You may want to design true human-like intelligent autonomous machines and systems, or simply build a better spam filter. But it all starts with a solid education. The future is built on these systems and technologies. The first step towards participation, acceptance, and engagement is understanding the constructive qualities distinctive to Artificial Intelligence (AI) and Machine Learning (ML).
