Machine Learning is emerging as one of the top 5 trending fields in the IT sector due to its intense use. Also known simply as ML, Machine Learning algorithms are being used in various IoT devices and the field of Big Data. Its popularity is expected to raise the market capital of ML from $15.5 billion in 2021 to $152.24 in 2028. This would be a Cumulative Annual Growth Rate (CAGR) of 38.6% in 7 years [Source: Fortune Business Insights].
The growing popularity is increasing the job roles in this domain, as a result, students are looking for certifications in Machine Learning, preferably online. Students are looking for a Machine Learning Course in Hyderabad, Bangalore, and Delhi, as these are the major IT cities of India and provide the highest employment and career opportunities.
Online courses provide adequate skills to candidates, which helps them in clearing interview rounds. IT fields like ML, Artificial Intelligence (AI), and Data Science are growing fast, and there are enormous developments. Thus, it becomes essential for candidates to keep up with the new incoming skills and earn expertise in them. To help your journey, we are listing the necessary skills below, commonly required in a Machine Learning Engineer. This’llThis’ll help you figure out what role suits you and how you fetch it easily.
Starting with the basics, Mathematics forms a base of all those fields which require computations and test case analysis. If you are a part of the majority who does not like Maths, it is not the time to make excuses, and you need to sit down to master this introductory course.
Mathematics is required in Machine Learning when you need to build upon your logic, choose a suitable algorithm, approximate confidence levels, and perform other quantitative techniques. Common principles of Maths which will be helpful in ML are:
- Multivariate Calculus
- Distributions like Poisson, Normal, Binomial, etc.
Maths is one skill you do not need to pursue in an online certificate course to master it. When going for a career in Machine Learning, added knowledge of Physics is also beneficial.
Many candidates presume that they will learn ML algorithms once set in their job. On the contrary, the ML algorithm is an essential skill that you should have well in advance to clear the interview rounds.
There are in total three kinds of Machine Learning Algorithms, and you should be aware of all of them. These include the categories of Supervised ML Algos, Unsupervised ML Algos, and Reinforcement ML Algos. Some of the common ML algorithms which you should go through are:
- Linear Regression
- Support Vector Machine
- Naive Bayes
- kNN (k Nearest Neighbours)
- Decision Trees
- Random Forest
- K Means
- Gradient Boosting Algorithm
- Hierarchical Clustering
A skill that goes without saying, software programming is essential for any development job, whether you go for Machine Learning, Testing, Data Analysis, or any other similar role. Learning programming helps in your current domain and keeps doors open for you in different IT job roles.
Major programming concepts which should be familiar to you include:
- Data Structures
- Operating Systems
Machine Learning Engineers should also have expertise in various coding languages, including script languages. Popularly used languages in Machine Learning are Python, R, Julia, Scala, Java, C++, TypeScript, etc.
Natural Language Processing
In short-termed as NLP, Natural Language Processing is required when you are training systems to memorize human actions and perform them independently. Through NLP concepts, you train your device to understand the complexities in the human voice and what all factors affect it, like tone, modulation, etc.
Human speech includes words that are not required, words that form slang and dialects, and various other components. Through NLP libraries, your device or system understands eliminating such components is almost equivalent to noise and plays no role in the final evaluation.
Some of the common NLP Techniques are:
- Sentiment Analysis
- Named Entity Recognition
- Text Summarization
- Aspect Mining
- Topic Modelling
Data forms the bedrock of any domain under Big Data like Machine Learning, Artificial Intelligence (AI), Data Science, etc. It is the analysis of this that makes all things possible. With enormous data generated today through various IoT devices, gathering insights has become easy. Still, all this is beneficial only when you can correctly analyze data.
Data Modelling refers to the combined strategy of analyzing gathered data, performing different algorithms to draw insights, and presenting them in a readable format. A machine learning engineer should know how to evaluate a dataset and discover patterns in it. Some of the concepts which help in proper data modeling and evaluation are:
- F1 Score (Also known as F score)
- Area Under Curve
- Mean Absolute Error
- Algorithmic Loss
Machine Learning is all about training your machine to learn like a human and make use of its “brain.” This is where neural networks enter into the picture, through which you help your machine develop neurons for its brain.
The neural network architecture in machine learning comprises two main layers: the Input Layer, which receives information, and the Output Layer, which presents that information in data. In between these two layers, multiple hidden layers transform information in question into meaningful actions and data.
Some of the common architectures in neural networks are:
- The Perception
- The Feed-Forward Network
- Recurrent Neural Network (RNN)
- Convolutional Neural Network
No job role exists which does not ask you to have some soft skills expertise. A Machine Learning Engineer’sEngineer’s role is a comparatively senior post, and you are required to interact with multiple people from different departments. Thus, you need good communication skills, leadership qualities, and negotiation ability.
Machine Learning Engineers have to deal with the product team, senior management, and even clients themselves. Therefore, mastering your communication is one thing you will never regret in your life.
Though there are multiple other skills that a Machine Learning Engineer should master, these are the most vital ones, and you should try your hands on them first. If you do not know of these skills, it is time to add them to your to-do list.
