Machine Learning and Data Science:

Machine learning shapes the world in many ways beyond the imagination. Look around you and you will find yourself immersed in the world of data science, take Alexa for example, a user-friendly AI beautifully built by none other than Amazon and Alexa is not the only one, there are more AI like Google Assistant, Cortana, etc.

 There's a question we're asking that's probably no less important than how to develop it, and what are the reasons to be developed in the first place? Well, we’ll try to dive into all these questions and we’ll also come up with some very reasonable but technical answers. The first and main question that arises here is what is machine learning and data science? 

 Data Science: 

 Many think that data science is an over-all of machine learning. Well, they’re partly right, because data science is just a lot of data and then applies algorithms, methods, and machine learning technologies to that data. Therefore, to master data science, you must be an expert in mathematics, statistics and also expertise. 

Well, what is subject matter expertise? 

The subject’s expertise, as its name suggests, is nothing more than domain knowledge to be able to abstain and calculate it. 

So basically, these three concepts are seen as the cornerstones of data science and if you can master them all, Well, congratulate yourself because you’re a level A data scientist. 

Let’s understand this using a diagram organized by Hugh Conway.
Now you know the term data science and what it includes. So, if this has sparked a spark in you to pursue this field as a career, there are a few things you may need to pay attention to! To become a data scientist, you will need immense knowledge in three important areas:

analysis, programming and domain knowledge. 

But you see that data science can’t be mastered just because you have some knowledge, but you will also need essential skills and to train the data scientist within you and to develop your skills, There are a few skills you can practice that will help you along the way:

Skills Python expert level, SAS, R, SCALA
Practical expertise in SQL coding.
Ability and ability to process unstructured data. 

Ability to understand various analytical functions.
Last but not least, knowledge of Machine Learning

Machine Learning:

As we said, machine learning could be considered a subset of data science, but the definition does not stop there. Very simple and reasonable machine learning could be that machine learning provides techniques for extracting data and then adds various methods for learning from the collected data, then using well-defined algorithms to predict future trends from the data.

Machine learning or traditional machine learning revolved around detecting models and then entering the hidden information of available data. Well, that was the elaborate definition of machine learning, but how do you justify that definition? A real functional example is very good in such cases and here the example would be GOOGLE.
Google is a great example of machine learning, because GOOGLE records the number of searches you’ve done, and then suggests similar searches when you search for something on Google in the future. Similarly, AMAZON recommends your products based on your previous searches, just like NETFLIX, depending on the TV show or movies you watched, you get a similar type of suggestions.

It’s not an unknown fact now, that the field of machine learning is growing exponentially around the world, so if you want to pursue a career in this field, There are a few skills that are essential for you to be able to prevail in this area.
