What is Machine learning?

Machine learning is a mathematical method which learns hidden patterns by analyzing the data and then make predictions on similar unseen data without human intervention. In simple Machine learning is a technique which makes machines think like humans. It can efficient learn the patterns from past data and make predictions.


Machine learning is powerful due to the fact that it can be used in various industries- like retail industries, hospitality industries, agricultural industries, healthcare industries, IT industries and many more.

Why learn Machine learning?

Recently, we are seeing a boom in artificial intelligence, data science and machine learning. But this not due to the fact that these techniques and methods didn't exist before, but this is because of the vast amount of data that we have nowadays and also because of the world class computer systems we have in the market. The introduction of fast GPUs and fast CPUs with high number of cores and threads have kickstarted Machine learning research in a big way. You can learn more on why learn Machine learning in my blog post - Why we need to know about Machine Learning? (ML001)


Future of Machine learning

The main advantage of Machine Learning is it's limitless applications. Nowadays, every industry is impacted by Machine Learning and artificial intelligence. It has helped industries grow and become efficient. Take for example, how machine learning has changed the healthcare sector. Nowadays, doctors are able to analyse a lot more data and come to a better conclusion. The medical scanning analysis has taken new turns and some of the algorithms provide better accuracy than humans interpretation. So, being a Machine Learning Engineer in the era of growing automation can be very fruitful.


With the world moving towards automation, there is a greater need for solving complex problems and that's where Machine Learning engineers come into the picture as they are the one who can solve these complex problems using Machine learning techniques.


Machine learning vs Data Science

Data Science

Data Science is the process of data analysis to produce rich insights about data which is of some business value. Suppose an user has visited an e-commerce website, then he or she generates data, which is stored in the backend, and this data is later on analyzed by data scientists. Based on the insights from that data, the system understand the users behaviour and shopping patterns, based on which it retargets advertisements and suggestions so to make the user buy a specific product(s).


A data scientist mainly deals with - data collection, data cleaning and aggregation, data analysis, data visualization and at the end collects valuable insights from the data. A data scientist or a data wizard as I call it, is responsible for making the weirdest connection between data and the business. Previously, we didn't have enough data to produce richful insights about businesses, but now with data, we have that leverage and that's when a data scientist comes into play. Data scientist is someone who brings up insights from chunks of data which otherwise would have gone unnoticed and understands the hidden patterns from that data.


From the business point of view, a data scientist looks after areas like predictive analysis, customer behaviour analysis, operational shortcomings, supply chain cycles, competition overview and more. We will cover these topics in details in another article.


Machine learning

In simple terms, Machine learning is a part of data science. Machine learning mainly deals with statistics and algorithms which are applied on the data. When there are huge chunks of data, the data scientist often find it very difficult to work with and that's when a machine learning engineer comes into the picture. The machine learning engineer uses machine learning algorithms like Linear Regression, Random Forest, Naive Bayes and many more. These machine learning algorithms are then applied to the data, and then it learns from the data. Machine learning algorithms are highly sophisticated and needs proper knowledge to understand the algorithms and its working.


What is a Machine learning engineer?

So, we have reached the point where we will be discussing our main point of this blog, which is what is Machine learning engineer. Machine learning engineer is someone who is skilled with probability and statistics, one who is good with differential calculus, good with algorithms and last but not the least, should be good in any programming languages (preferably Python). One who's job is to work along with datascientists and make sure that whatever models they are using for the given data, works well and after which the datascientists can go forward and discuss the insights from data to the stakeholders of the company. So, a machine learning engineer's work is to understand the data first and find out the hidden patterns in the data through an array of models or build an custom model which works best with the given data.


They use programming frameworks and big data methods to make sure that the data pipelines are collecting the raw data and using them to make the machine learning models more efficient and reliable. They also work towards making sure that the machine learning applications that they build also works realtime and provide the best results.


Understanding the ecosystem

For understanding the AI ecosystem, we have to understand the state of AI and its past. AI research came in early into existence early 1960s after which it got faded away. But with recent advancement in the fields of computer systems and big data bloom, the AI ecosystem started to begin. Fast computer systems and high speed processors coupled with graphics card can process TBs of data within no time. Companies starting to gather data from all sources has also accelerated the AI research in different fields.


Coming back to the AI ecosystem, currently we are focused on shallow AI or which can be termed as narrow AI too, basically means that the AI systems are not generalized across spaces. They are capable of doing simple tasks and tasks which they are trained for. The AI which we see in fictional movies is called the Artificial General Intelligence (AGI) which is a topic in itself. We will later cover AGI in future blog posts.


AI ecosystem consists of many segments which includes - Machine Learning, Deep learning, Artificial Narrow Intelligence. Machine Learning is a subset of AI which deals with algorithms whereas deep learning allows us to imitate a human mind which finds patterns in data and provide improvements in technologies like self driving cars, facial recognition etc. Artificial Narrow Intelligence deals with narrow AI tasks which are limited to specific tasks.


Life as a Machine learning engineer

I will posting How I spend a day as a Machine learning engineer in a later blog but for now I will discussing about life as a Machine learning engineer. The machine learning engineer job in the IT sector is seeing a heavy growth. As more and more research work is being done in AI, companies are now including AI in their workflow, be it Health, Pharma, IT, Finance, Manufacturing, Retail, Hospitality and many more. So, naturally companies are rapidly hiring Machine learning engineers to cater their AI needs. In the next decade we will see lot of machine learning engineers being hired to help companies integrate new technologies to their existing workflow and become more efficient.


The daily life of a Machine learning engineer is similar to that of a computer engineer but they are more focused on creating algorithms and pipelines to make the machines self learnable. Machine learning engineers may be deployed in various industries, he/she has to understand what kind of data is coming in, how to create efficient models to train the data and how to deploy it at the edge to cater the needs of that industry. (Note - Data from various industries will be completely different from each other, so a Machine learning engineer has to first understand the data and accordingly build machine learning models and later on finetune machine learning models to make them more efficient).


A machine learning engineer apart from doing his daily work which is already exiciting as he/she gets to work with real world data, also needs to keep themselves updated with all the latest AI research taking place (including AI research papers, AI Journals, AI open source projects) which will make sure that they stay ahead in the field of AI.


Roles and Responsibilities of a Machine learning engineer

A machine learning engineer as we all know deals with data. Now we will be discussing in details about how a Machine learning engineer really does as we dive deep into it. The machine learning engineer works with big data and tries to find out patterns in that data using machine learning models which helps him find out patterns in that data.


The machine learning engineers are responsible for making sure that the models work with big data as the volume of data which they work with will be huge. They need to scale their machine learning models in order to cater the needs of ever increasing real time data. In the next few points we will be discussing about their responsibilities of a machine learning engineer and their roles.


The roles and responsibilities of a Machine learning engineer are -

  • Understanding the computer algorithms, data sturctures and computer architecture to be able to easily scale up

  • Applying the mathematical theories and formula to understand the algorithm or to make custom algorithms

  • Make data pipelines and applications for production which can be easily scaled

  • Using different techniques and models that best suit the data and can derive the hidden patterns in that data.

  • Demonstrate the algorithms and the models to the data scientist in an easily understandable way

  • To be able to discuss with the stakeholders and the business persons about the strategies and understanding their requirements

  • Help other computer engineers working alongside to better integrate the machine learning flow into the application

There are different types of machine learning engineer ranging from applied machine learning engineer to core machine learning engineer. An applied machine learning engineer is someone who focuses on computer basics and fundamentals while applying machine learning models at a higher level. While a core machine learning engineer is one who focuses mainly on machine learning algorithms, design custom machine learning models and creating the data pipelines which ensures scalability. Depending on the requirements of the company, a machine learning engineer needs to adapt to scenario.


Pre-requisite for a ML engineer
