Frequently Asked Questions

A.I. and Machine learning

Artificial Intelligence vs. Machine Learning: Are They the Same?

Artificial intelligence and machine learning are two trendy and constantly excited terms these days. At times, both terms are used interchangeably to define a smart system or intelligent software. 

While both AI and ML are based on mathematics and statistics, they are different.

What is Artificial Intelligence? 

Artificial Intelligence is the computer’s ability to imitate or mimic intelligent behaviors of humans and execute human-like tasks. AI performs tasks that need human intelligence like reasoning, thinking, learning from experience, and making decisions. As John McCarthy would put it, “AI is the science and engineering of making intelligent machines.” 

AI can do tasks very well. However, they have yet to teach the capacity to interact with humans at an emotional level. To better understand artificial intelligence, let us check some common examples.

Robotics: One good example of artificial intelligence is a robot. Industrial robots can monitor their performance and accuracy. They can even detect and recognize when they need maintenance to avoid expensive downtime. Robots also can act in an unknown or a new environment. 

Personal Assistants: Personal assistant tools are another sample of artificial intelligence. These human-AI interaction gadgets are very popular today– Siri by Apple, Google Home by Google, Cortana by Microsoft, and Alexa by Amazon. These gadgets allow you to book hotels, find out information, schedule meeting, add calendar events, answer questions, send messages or emails, and so many more. 

What is Machine Learning? 

As the subset of artificial intelligence, Machine Learning learns automatically from data without being assisted or programmed by domain expertise. The “L” in ML refers to the machine’s ability to learn based on data.

The ML algorithm also can evaluate its accuracy or performance, train a model, and make predication. For example, you can train a whole system with a supervised machine learning algorithm like Decision Trees and Random Forest. 

Machine learning allows machines to learn by themselves thru data and make accurate predictions. Machine learning is essential since this allows enterprises to check operational business patterns and customer behavior. Machine learning also supports new product developments.

Today, most leading companies, like Uber, Google, and Facebook, utilize machine learning as their central part of the operation. Undoubtedly, machine learning is now a significant competitive differentiation for a lot of companies. 

Free Courses Online AI Machine Learning - fact

To understand more about machine learning, here are some examples:

Product Recommendations. The majority of e-commerce websites today have machine learning tools that can provide recommendations of products just by checking on their historical data. 

Say, for instance, if you searched for house renovation books on Amazon, and you bought some of them, the moment you come back after some time, Amazon’s homepage will show you a list of other books related to house renovations. This will also give you recommendations based on what you added to your car, what you liked, and other related actions. 

Malware and Email Spam Filtering. Spams are unwanted commercial bulk emails that are massive problems for a lot of internet users. Thankfully, most email service providers today use machine learning tools to learn and recognize phishing and spam emails automatically. 

For example, Yahoo and Gmail spam filters do not only check for spams emails utilizing pre-existing rules. They also generate new rules from what they learned and continue their spam filtering operations. 

To sum it all up, artificial intelligence solves tasks needing human intelligence. At the same time, machine learning is simply a subset of AI that deals with solving specific tasks by learning from data and creating predictions. Meaning, all machine learning is artificial intelligence, but not all artificial intelligence is machine learning. 

Why Should You Learn Artificial Intelligence?

Artificial intelligence is named the “Sexiest Job of the Century,” It can help you earn a lot! AI opens a whole world of opportunities. Today, we are in a world where calling Alexa, Google, or Siri is more normal than calling our friends and family.

Artificial intelligence has indeed evolved and is no longer limited to sci-fi shows and movies. It is practically all around us. But why should you learn artificial intelligence?

AI is the skill of the century. Not just the skill of the year, not decade, but a century! AI is now all set to replace jobs that humans used to do. However, this also means making 130 million roles (or more) in all major sectors.

Thus, to be a part of this group, you have to be a part of the transformation. AI is today’s emerging technology establishing a name in practically all industries: from fashion to finance. AI jobs account for 18& of jobs in many companies. 

Data, Data, and More Data. Humans generate almost three quintillion bytes every single day. We collect data from what we use when we see or how we communicate.

People feed these collected data to machine learning algorithms to obtain a behavioral pattern– information about consumers. This information will eventually transform into insights. Thus, companies are siding towards AI in hopes of obtaining more sales and ultimately getting on top.

Artificial intelligence, as cliché as it may sound, has everything in its bag to stand out. AI is versatile. By mentioning the term “artificial intelligence,” this can quickly draw people’s minds to either space-related industries or computers.

But keep in mind that AI has critical roles in other leading industries like healthcare, banking, security, fraud detection, mobile, clothing, and a lot more. 

For example, VSA (Virtual Health Assistants) helps patients guarantee appropriately prescribed, suggest fundamental health treatments, endorse preventive screenings, and even give relevant diet recipes based on one’s medications or illness history. 

Artificial Intelligence is everywhere. Small and medium businesses customize their websites with a unique user experience knowing this is more inviting. The use of mobiles and the internet have allowed people to navigate the information they need via a store’s website, instead of physically going to shops.

You can even interact with chatbots (customer support), an automated computer program that ‘talk’ like a human and allow visitors to engage and interact seamlessly. 

Why Should You Learn Machine Learning?

Machine learning course

Gone were those days when machine learning was nothing more than a niche subfield of computer science. Today, technology giants are using machine learning.

Walmart uses machine learning algorithms for product recommendations, Uber for surge pricing, Twitter for their contents, and even fraud and detection at top financial firms.

The most widely used social media platforms—with Facebook, Instagram, and Twitter leading the pack—also use machine learning for display feeds. No doubt, the future of machine learning is finally here!

But should you learn machine learning at all? If so, why? Here are the top reasons.

Better career opportunities. A study by Tractica Report revealed that machine learning (as a service) is expected to increase from $10.7 billion in 2016 to $19.5 billion by 2025. As of the moment, machine learning is the star of the show. Every industry is finding ways to apply artificial intelligence in its domains.

Thus, focusing on machine learning will help open a whole world of possibilities in developing cutting-edge ML applications in various industries like medicine, cyber security, and so much more.
