One of the terms we hear often since the advent of the Digital Age is Data Science. However, we tend to overlook that this field has been around for a long time. Like Old wine in a new bottle, it has just gotten a makeover with the emergence of Computer Science and Information Technology.

In simple terms, Data Science is the Study of Data. From the Neanderthal Man who analyzed an existing problem of transportation and created the wheel to NASA sending the first men to the Moon, all of those achievements were possible due to careful analysis and extraction of information from obtainable data.

The best and most relatable example to describe this process is the Netflix Algorithm. Their Model analyses the data from millions of viewers, which then helps to create personalized suggestions for further viewing. Now, the question might arise, is it possible to continuously sift through never-ending lines of data and still maintain your sanity? It is at this point, machine learning, a subset of the data science field comes in.

Data Science and Machine Learning

It has been understood now that to produce data in an operational format, algorithms or models developed by a data scientist will have to be used. These algorithms are then trained continuously in defined intervals by the data scientist or machine learning engineer until it is able to extract required data from the given data sets independently.  The knowledge required to train these algorithms is derived from the fields of artificial intelligence and machine learning. The diagram below will give a broader understanding of how all these domains interact.

Fields of Data Science

Machine Learning from scratch

On the same note, one can simply define machine learning as the process by which machines learn and analyze data independently without human intervention. However, to reach that autonomous level of programming, it requires intensive human expertise in training the machines and programming them to utilize their artificial intelligence. And that effort can only be provided by certified individuals.

Could you be one of them? Definitely! Upskilling oneself in any given field has now become a pretty straightforward process.  Yet, choosing the exact portal that can propel you in your desired direction can be quite an uphill task. But before diving deeper, it is always preferable to straighten out the fundamental knowledge. Like everything related to the Computer Science field, machine learning to requires a basic familiarity with languages like Python, C++, and R.

Machine learning using Python

Python is by far the easiest and most popular language used by both machine learning beginners and experts. The advantage lies in the fact that it is an open-source programming language with a vast community of users. Also, the many library packages provided, ease the process of coding. Platforms like Github have a considerable amount of code provided by Python users worldwide that could easily help an aspiring beginner with his/her kick-off project. Once the basics of the language are clear, all that remains is to start training the data sets.

Machine Learning using Python

Neural Networks in Python

Neural Networks is the mechanical interpretation of the human body’s nervous system. Vast connections and interconnections of inputs that pass through different functions and assemblies to give a desired/fixed output. A simple example would be the binary OR table.

Input Input Output
0 0 0
0 1 1
1 0 1
1 1 1

This can be coded using python and after training the program for different levels and data sets of the given table, the system will be able to handle any binary OR table independently. This is just a tiny drop of what neural networks can achieve through python. Single programs can handle millions of bytes of data and produce outputs in exponentially fast time frames.

Python for Data Science

Python for Data Science is not much different from Machine Learning using Python. As machine learning is a field encompassed within the Data Science Industry, Python for data science deals with the methods of using the language for Machine learning, artificial intelligence and deep learning. Learning the programming fundamentals with respect to the Data Science industry will help in paving a smooth entry to careers as Data Scientists.

R for Data Science

R is a programming language extensively used for statistical research. An open source programming language like Python, it also has numerous specific libraries to help in the creation of code for machine learning, data analysis or statistical inference.

As per research, it is the language highly favored by the academic and healthcare industries due to its high-functioning capabilities of structuring any given random/varied data. In addition, companies like Twitter, Google, Facebook and Microsoft also utilize the language extensively to improve their user interactivity.

Statistics for Data Science

“Mathematics is the music of reason”, said James Joseph Sylvester, An English Mathematician. Statistics, a branch of mathematics, is truly the backbone and underlying reason for the Data Science Industry. Like the famous phrase , “A chain is no stronger than its weakest link”, having substantial knowledge in the computer science domain but none in the statistics domain can make your chain one important link weaker.

A good knowledge in statistics can ensure whether a data scientist just survives or thrives in the industry. If you can code on command, but are unable to differentiate between the structured and unstructured data, or divide into data sets based on the statistical findings, your role and influence in the industry would be greatly limited.

Artificial Intelligence and Machine Learning

Similar to how Machine learning is a field within the Data Science Industry, Machine learning is a subset of the Artificial Engineering Field. Wherein machine learning trains machines to parse through data and interpret it in meaningful ways, Artificial Intelligence aims to emulate the complete human psyche in a machine.

Yesteryear science fiction ideas have been implemented and are running thanks to the improvements in the AI field. Even some of the more traditional fields like the Automobile Industry seem to be benefiting from the AI revolution.

Driver less cars, personalized AI operators etc. have taken the industry by storm. Many Automotive OEMs (Original equipment manufacturers) like Ford, GM etc. have dedicated teams to work towards the development of Autonomous Drive Vehicles. These are vehicles that can function perfectly and follow all rules without any human intervention. So, the need for data scientists even in these seemingly traditional fields will skyrocket in the coming years.

Deep Learning with Python

Deep learning, in simple terms, is a machine learning technique. Deep learning uses neural networks to help the machine analyze the data and predict the outcomes much like a human brain would. From a visual standpoint, it could be imagined as a bridge between the AI and machine learning fields.

Introduction to Data Science

Now that you have a clear and fundamental idea of the Data Science Industry, you can put a foot forward and upskill yourself. The process of choosing a course can be very daunting and tedious, without careful research you could end up with a course that goes right above your heads or a course that makes you re-learn your ABCs.

Your first step would be to prioritize your requirements, what do you aim to achieve from the course? Is your end goal to become a data scientist? Or are you doing it for the love of knowledge and keeping up with the latest technological trends? Make a list and answer all these questions, after which you can use your answers to skim through courses and decide what fits your interests best.

Won’t buying the necessary books suffice to learn about the field?
If you noticed, this article contained images of various books you could refer to. Yes, books will be an important part of the journey, but they alone won’t be sufficient. If that were the case, the school wouldn’t be required and everyone could study individually.
Exposure to peers interested in the same field and experienced tutors are extremely essential to build the working knowledge, as theory knowledge alone is not sufficient

If I don’t have a background in engineering, will I be able to cope with the pace of the industry?
Research suggests that 32% of data scientists are math majors and only 16% are engineers. The degree doesn’t matter as long as you have the interest to learn.
