If you wish to make your career in network, the Certifications is considered to be the best certification, to jump-start your career. But gaining this certification isn’t considered to be that much easy. You have to go through lots and lots of study process unless you have the help of the CCNP 300-610 Dumps offered at the ExamClubs.
On one hand, Machine Learning Engineers get slightly more paid than Data Scientist, on the other hand, the demand or the Job openings for a Data Scientist is more than that of an ML Engineer. This is because ML Engineers work on Artificial Intelligence, which is comparatively a new domain.
Now the skill requirements for Machine Learning Engineer vs Data Scientist are very similar, so let’s start with the Common Skillsets.
- Programming Languages: The first and foremost requirement is to have a good grip on a programming language, preferably python as it is easy to learn and its applications are wider than any other language.
Although Python is a very good Language, it alone cannot help you. You will probably have to learn all these languages like C++, R, Python, Java and also work on MapReduce at some point.
- Statistics: Wikipedia defines it as the study of the collection, analysis, interpretation, presentation, and organization of data. Therefore, it shouldn’t be a surprise that Data Scientists, as well as Machine Learning Engineers, need to know statistics. Familiarity with Matrices, Vectors, and Matrix Multiplication is required.
- Data Cleaning and Visualization: Data cleansing is a valuable process that can help companies save time and increase their efficiency. Being able to tell a compelling story with data is crucial to getting your point across and keeping your audience engaged.
If your findings can’t be easily and quickly identified, then you’re going to have a difficult time getting through to others. For this reason, data visualization can have a make-or-break effect when it comes to the impact of your data.
- Machine Learning and Neural Network Architectures: Machine Learning and predictive modeling are quickly becoming two of the hottest topics. You need to know Machine learning techniques such as supervised machine learning, decision trees, logistic regression etc. These skills will help you to solve different data analytical problems that are based on predictions of major organizational outcomes.
Deep Learning has taken traditional Machine Learning approaches to a next level. It is inspired by biological Neurons (Brain Cells). The idea here is to mimic the human brain. A large network of such Artificial Neurons is used, this is known as Deep Neural Networks.
- Big Data Processing Frameworks: A huge amount of data is required to train Machine Learning/ Deep Learning models. Earlier because of the lack of data and computational power, creating precise Machine Learning/ Deep Learning models was not possible. Nowadays a huge amount of data is generated at a good velocity.
Therefore, we require frameworks like Hadoop and Spark to handle Big Data. Nowadays, most organizations are using Big Data analytics to gain hidden business insights. It is, therefore, a must-have skill for a Data Scientist and Machine Learning Engineers.
- Industry Knowledge: The most successful Projects out there are going to be those that address real pain points. Whichever industry you’re working for. You should know how that industry works and what will be beneficial for the business. If a Machine Learning Engineer or a Data Scientist does not have business acumen and the know-how of the elements that make up a successful business model, all those technical skills cannot be channeled productively.
You won’t be able to discern the problems and potential challenges that need solving for the business to sustain and grow. You won’t really be able to help your organization explore new business opportunities.
- Computer Vision: Computer Vision and Machine Learning are two core branches of Computer Science that can function and power very sophisticated systems that rely on CV and ML algorithms exclusively but when you combine the two, you can achieve even more.
Must-Have Machine Learning Engineer Skills
- Language, Audio and Video Processing: Since Natural Language Processing combines two of the major areas of work ie. Linguistics and Computer Science and chances are at some point you’re going to work with either text or audio or video.
So it’s necessary to have good control over libraries like Gensim, NLTK, and techniques like word2vec, sentimental analysis, and summarization.
- Applied Mathematics: A lot of machine learning techniques out there are just fancy types of function approximation. Having a firm understanding of Algorithm theory and understanding subjects such as Gradient Descent, Convex Optimizations, Quadratic Programming, and Partial Differentiation will help a lot.
- Signal Processing Techniques: One of the few Machine Learning Engineer Skills is also the understanding of Signal Processing and having the ability to solve different problems using Signal Processing techniques as feature extraction is one of the most important parts of Machine Learning.
Knowledge of Time-frequency Analysis and Advanced Signal Processing Algorithms such as Wavelets, Shearlets, Curvelets, and Bandlets will help you to solve complex situations.
- Software Development: Machine Learning Engineers are also software developers and are sound in it. It is important to have a good understanding of topics like Data structures, Memory management, and classes. One must know how to package Software, Software Development Life Cycle, Modularity and Design Patterns.
Must-Have Data Scientist Skills
- Creative and Critical Thinking: Data Scientists must look at the numbers, trends, and data and come to new conclusions based on the findings. It’s said that smart people ask hard questions while really smart people ask simple ones. Indeed, many of the most important questions you can ask about your company are the simplest. Using data to find answers to your questions means figuring out what to ask in the first place. That can be quite tricky!
- Effective Communication: You’ll need to explain a lot of concepts to people with little to no expertise in the field. Chances are you’ll need to work with a team of engineers, as well as many other teams.
Communication is going to make all of this much easier. Companies searching for a strong Data Scientist are looking for someone who can clearly and fluently translate their technical findings to a non-technical team, such as the Marketing or Sales departments.
