Now, we’ll be looking at the most frequently asked questions by beginners in the field of Machine learning.
Frequently asked questions by Beginners in ML
As a beginner, it’s natural to have a lot of questions regarding ML. We’ll be addressing the top three frequently asked questions by beginners or non-programmers when it comes to Machine learning:
Q.1 I am looking to make a career in Machine learning but I have no prior programming experience. Do I need to know programming for Machine learning?
In a nutshell, Yes. If you want a career in Machine learning then having some form of programming knowledge really helps. As mentioned earlier in this article, learning a programming language can really help you with implementing ML algorithms. It also lets you know the internal mechanism behind Machine learning. So, having programming as a prior skill is great. Again, as mentioned before, you can get started with Python which is the easiest and the most common languages for ML.
However, programming is just a part of Machine learning. For instance, “machine learning engineers” typically write more code than develop models, while “research scientists” work more on modelling and analyzing different models. Now, ML is based on the principles of statistical inference and for talking statistically to the computer, we need a language, there comes Coding.
So, even though the nature of your job in ML might not require you to code as much, there’s still some amount of coding required.

Q.3 Do I need to know advanced mathematics ( college graduate level ) to learn Machine learning?
It depends. As mentioned earlier, understanding of the following mathematical topics: Probability, Statistics and Linear Algebra can really make your machine learning journey easier and also help simplify your code. These help you understand the “why” behind the working of the machine learning algorithms, which is quite fundamental to understanding ML.
However, not knowing advanced mathematics is not an excuse to not learning Machine Learning. There a lot of libraries which makes the task of applying an ML algorithm to solve a task easier. One such example is the widely used Python’s scikit-learn library. With scikit-learn, you just need one line of code and you’ll have the most common algorithms there for you, ready to be used.
But, if you want to go deeper into machine learning then knowing advanced mathematics is a prerequisite as it will help you understand the algorithms, the formulas, how the learning is done and many other Machine Learning concepts. Also, with so many courses and tutorials online, you can always learn advanced mathematics on the side while exploring Machine learning.
So, we looked at the three most asked questions by beginners in the field of Machine Learning.
In the past, machine learning has provided us with self-driving cars, effective web search, speech recognition, etc. Machine learning is extremely pervasive, in fact, many researchers believe that ML is the best way to make progress towards human-level AI.
Learning ML is not an easy task but its not next to impossible either. In the end, it all depends on the amount of dedication and efforts that you’re willing to put in to get a grasp of it. We just touched the tip of the iceberg in this article, there’s a lot more to know in Machine Learning which you will get a hang of as you get your feet dirty in it. That being said, all the best for the road ahead!
