Over the past ten years, machine learning has quietly transformed our world. We rely more and more on devices and programmes that use machine learning at their heart, from taking selfies with a blurred background and focused face capture to having virtual assistants respond to our questions. In brief, technologies like artificial intelligence (AI), machine learning, data science, etc., are becoming more and more commonplace these days. But these innovations are also used casually, and many people are unaware of their true meanings or the skills needed to learn them. To help you with this, we are counting down the Top 10 essential skills to become a Machine Learning Engineer.
Top 10 Essential Skills to Become a Machine Learning Engineer
1. Applied Mathematics
Mathematics plays a critical role in machine learning, which makes it one of the essential skills to become a Machine Learning Engineer. ML could be employed in mathematics in a variety of ways. The right ML algorithm for a given set of data can be chosen by applying formulas from linear algebra, probability, statistics, multivariate calculus, distributions like Poisson, normal, binomial, etc. Set parameters and approximative confidence levels are other options. Many Machine Learning (ML) algorithms are adaptations of statistical modeling techniques. Knowing a little bit about physics ideas in addition to maths can be useful.
2. Computer Science Fundamentals and Programming
You must be proficient in a variety of computing concepts, including data structures (such as stacks, queues, trees, and graphs), algorithms (such as searching, sorting, dynamic and greedy algorithms), time and space complexity, etc. A bachelor’s degree in computer science will enable you to gain this knowledge. You’ll have a solid understanding of a variety of programming languages, including Python and R for machine learning and statistics, Spark and Hadoop for distributed computation, SQL for database administration, Apache Kafka for data pre-processing, etc. Being familiar with Python’s libraries, such as NumPy, Pandas, Matplotlib, Scikit-learn, TensorFlow, etc., will be an added benefit.
3. Neural Network Architectures
In machine learning projects, neural networks are a predefined set of algorithms. There are various Neural networks, including Feedforward Neural Networks, Radial Basis Function Neural Networks, Recurrent Neural Networks, Convolutional Neural Networks, etc. They are constructed with several layers and are modeled like the neurons in the brain. One layer is the input layer, which gathers information from the outside environment and modifies it for the output layer after passing through an array of encoded levels. These reveal an in-depth knowledge of parallel and orderly calculations used in learning or data processing. It is one of the essential skills to become a Machine Learning Engineer.
4. Data Modeling and Evaluation
A Machine learning model processes enormous volumes of data and uses predictive analytics to make decisions. When working with such large data quantities, data modelling and evaluation are crucial for determining how effective the final model will be. Data modelling entails comprehending the basic framework of the data and then sifting through it for hidden patterns. A proper algorithm must also be used to evaluate the data. The naïve beyes algorithm, which is good for large data and speed, or the random forest approach, which is good for accuracy, could be used for classification or regression.
5. Advanced Signal Processing Techniques
Understanding signal processing and being able to use its methods to address various problems, such as feature extraction can help you understand the pain points of many complex problems. Signal processing’s main goal is to reduce noise and retrieve the signal’s best qualities. Time-frequency analysis and advanced signal processing algorithms like Wavelets, Shearlets, Curvelets, and Bandlets can be applied to solve many complex problems. Machine learning and signal processing can also be applied as orthogonal techniques, where domain knowledge is combined with traditional signal processing to produce signal representations that are appropriate for machine learning.
6. Natural Language Processing (NLP)
One of the core components of machine learning, NLP tries to teach computers human language in all of its complexity. The core of NLP is made up of a variety of libraries. By breaking the text down according to its grammar, extracting key phrases, deleting unnecessary words, etc., these libraries can be used to help computers understand natural language. To master this, get acquainted with a few of the libraries, such as the Natural Language Toolkit, which is favored for developing NLP-based apps.
7. Language, Audio and Video Processing
Since Linguistics and Computer Science are combined in Natural Language Processing, there is a good likelihood that you may work with text, audio, or video at some time. This is why it is crucial to be well-versed with tools like Word2vec, sentiment analysis, and summarization as well as libraries like Gensim and NLTK. From the audio signals themselves, useful information is extracted during voice and audio analysis. Having familiarity with the applications of Fourier transformation will be extremely beneficial.
8. Machine Learning Algorithms
Having an in-depth understanding of popular machine learning algorithms can help you decide where to use which ones. ML algorithms categorically fall under supervised, unsupervised, and reinforcement learning algorithms. Some of the popular ML algorithms include the Apriori Algorithm, Naive Bayes Classifier, K-Means Clustering, Support Vector Machine, Linear Regression, Logistic Regression, Decision Trees, and Random Forests. While it could be difficult, it is essential to have a solid understanding of these algorithms.
9. Industry Knowledge
The machine learning initiatives that focus on actual problems will be the most effective. Regardless of the industry you are in, you ought to be familiar with the operations of that sector and how it will be advantageous to the company. All of those technical talents cannot be used effectively if a machine learning engineer lacks business savvy and an understanding of the components of a successful business strategy. You won’t be able to identify the issues and potential obstacles that must be overcome for the company to survive, develop, and take advantage of new opportunities.
10. Effective Communication
Having strong communication capabilities can be a major USP. This is due to the fact that, even though you are the best at analysing the data and insights produced by machine learning, it is also crucial that you are able to communicate these insights to non-technical team members, shareholders, or clients. This may also entail data storytelling; in which case you must be able to convey your data in a narrative fashion with a beginning and a finish with real outcomes you have attained using machine learning. That’s because, in the end, a company will place a higher value on practical insights than on data analysis.
Conclusion
And those are the 10 Essential skills to become a machine learning engineer. Machine learning is spreading rapidly and securing a place in industries like healthcare, cybersecurity, and other fields as digitalization advances. Because of the scenario, it is prudent to study more about machine learning and train to be a machine learning engineer.
