“Mathematics is the language with which God has written the universe.”

∼Galileo Galilei

According to the all-mighty knowledge base, Wikipedia, mathematics is an area of knowledge that includes the topics of numbers, formulas, related structures, shapes, and the spaces in which they are contained, and quantities and their changes. This so-called language of the universe includes some major subdisciplines such as Number theory, Calculus, Analysis, Algebra, and Geometry. This subject is a really interesting subject that helps us to understand and work with numbers, shapes, patterns, and logical reasoning. Simple mathematics is all about counting, measuring, and describing things in a more organized and precise way. It helps us to get some proper answers to questions like, “How much?”, “How many” and find the patterns and links between various parameters that the whole world depends on.

For example, if you want to know how much money you’ll have after saving a certain amount each month, mathematics can help you calculate it. If you want to figure out the area of a rectangular room, mathematics can help you find the right formula to get the answer. It also plays a crucial role in everyday activities like telling time, measuring ingredients for a recipe, or budgeting your salary. And mathematics is not only about numbers and symbols which construct mind-bending equations and theories like in algebra but also about understanding and describing shapes and their properties.

And our supporting roles here, AI and ML. What are they? Why is this 21^st century so serious about these few letters? Artificial Intelligence or AI is a field of study in Computer science that focuses on creating intelligent machines that can think and respond like humans. It’s about designing and developing computer programs and systems that can understand, reason, and make decisions on their own, without being explicitly programmed for every task.

Just like our brains learn from experience, AI systems can learn from data. They use special algorithms and techniques to analyze large amounts of information and recognize patterns. This allows them to perform tasks like recognizing texts and images, understanding speech, generating content, and even playing complex games such as Go and Chess. AI also has a vast amount of practical usage such as generating creative content, translating languages, giving out better recommendations, and assisting on find human diseases as well.  AI systems can adapt and improve over time, getting better at their tasks as they gather more information. So, there is no doubt that AI is changing the way people do their everyday tasks.

Machine Learning or ML is a major subdiscipline of AI that focuses on teaching machines to learn from experience and get better over time, just like humans do.  That is more accurate to describe this as training a computer or a machine to learn by itself, recognize patterns and respond accordingly to them. In traditional computer systems and programs, humans should tell them everything that has to be done. But in AI and ML, human only needs to give some amount of data and let them figure out the existing patterns and makes their own decisions.

Here’s how it works: First, we provide the computer with a lot of examples or data. The computer analyzes this data and looks for patterns and relationships. It tries to learn from these patterns so that it can make predictions or decisions on new, unseen data. The more examples the computer sees, the better it becomes at recognizing patterns and making accurate predictions. It keeps learning and improving as it gets more data. Machine Learning is used in various applications, like voice recognition, recommendation systems, and even self-driving cars. It’s an exciting field that helps computers become smarter and more helpful in our daily lives.

Given our understanding of mathematics, AI, and ML, we come to an important question: how do these elements interconnect? While it’s clear that AI and ML are closely related, the role of mathematics in this collaboration becomes essential to explore. Mathematics, renowned for its proficiency in handling numbers, shapes, and patterns, plays a significant role in the realm of AI and ML. So, how exactly do numbers, shapes, and patterns intertwine with AI and ML, and what significance do they hold in these fields?
