“I’ve learned over the years that when it comes to success, consistency is key. Consistent hard work that we may not like doing today, but for a payoff, we’ll love tomorrow. Earn it. Enjoy it.”— Dwayne Johnson
As per specifics revealed by Glassdoor, the average base earning for a machine learning engineer is more than $114,000 annually in the US as we enter the New Year 2021. Besides, you can also enjoy more benefits, such as bonuses and equity, which can help you to earn more than your base pay as your career as a machine learning engineer moves on successfully.
Let’s shed some light on the essentials facts associated with becoming a successful machine learning engineer.
What is Machine Learning and Why is it such a Big Deal?
Machine learning is one-of-a-kind technique of creating innovative systems that can successfully analyse pre-existing data, and successfully learn patterns as well as make decisions or predictions and classifications or any other relevant tasks based on similar data, with least human involvement.
To put it simply, ML is the technique where we are training a computer to learn from previous data in order to carry out tasks for us in a comparatively better way in the future.
As far as machine learning is concerned, it differs from the conventional programming in so many ways. In the case of traditional programming, a human workforce enters data into a computer while developing a program that is specifically designed to alter that particular data into the preferred output.
On the other hand, we provide input for the machine in case of machine learning and depending on what the previous data provided. The machine successfully develops its own logic based on the preferred output.
The key point is that the machine learns without any human interference in MI. It may look like something that’s restricted to research work, but it’s a technology that we can easily witness in many applications that we come across in our daily life. Moreover, machine learning is not programmed but rather taught with data.
What is a Machine Learning Engineer?
Whenever a job involves the word “engineer”– this can easily tell you that the nature of the job is hands-on, and the person hiring you is expecting that you can easily write code on a daily basis. It’s not just limited to building models and relating only to theory.
The basic job of a machine learning engineer is to actually build machine learning systems and to put the build models into production. One of the biggest companies in the world, such as Amazon also hires MI Scientists that focus on theory mainly. However, its software engineering roles will need some kind of machine learning.
It is also worth mentioning here that a machine learning engineer also is not a data engineer. As far as a data engineer is concerned, he/she is has a more precise role that mostly focuses on accumulating and transforming data prior to analysis. On the other hand, a machine learning engineer needs a thorough understanding of data engineering too. The systems being built by a Machine Learning engineer will span the entire data pipeline.
Machine Learning Engineer and the New World of Artificial Intelligence
With more and more innovations in the IT field, careers as a machine learning engineer are rapidly becoming one of the most preferred positions. Every now and then, more companies are leaning towards AI technologies, including machine learning, and even more, companies are planning on adopting this new writing on the wall within the next five years.
Machine learning engineers can find exciting positions in a variety of industries, many of which will enable them to have a significant contribution to how society interacts with technology and how it enhances our lives.
While keeping in view the fact as to how rapidly the world of machine learning is moving, the life of a machine learning engineer can be something you dreamt of. Being a machine learning engineer, you can be part of some of the most exciting happenings in the world of Artificial Intelligence.
If you are someone who seeks a position as a machine learning engineer, you are having an exciting career path ahead of you. Along with developing applications that can easily enable machines to self-learn and carry out tasks without any particular human programming, machine learning engineers can move on to attain a position as an architect that works to develop out-of-the-ordinary application prototypes.
The best part of being a machine learning engineer is that you can easily work in a broad range of professional capacities, filling several positions including machine learning engineer, principal machine learning engineer, machine learning software engineer, lead machine learning engineer, senior machine learning engineer, machine learning research scientist, data scientist positions, machine Learning Engineer experience and skills.
Machine Learning Engineer Experience and Skills
As far as qualification is concerned, machine learning engineers are required to have a master’s degree in most of the cases, and sometimes a PhD in computer science or any relevant field is also mentioned in requirement by big companies.
In addition, a machine learning engineer should also have advanced knowledge of mathematics and also data analytical skills as both are crucial components of a machine learning engineer’s background.
Owing to the fact that processes and results need to be communicated to management and other outside stakeholders, it is also necessary that machine learning engineers should have strong written and oral communication skills.
Some of the employers also expect specific experience and knowledge from a machine learning engineer as they required being an essential part. Some of these skills include,
1. Core Programming Skills and Computer Science Fundamentals
Computer science fundamentals are core part of machine learning, and ML engineers need to have basic knowledge of core skills such as data structures such as stacks, queues, trees, multi-dimensional arrays and graphs to name a few. He/she also need to have a better knowledge of algorithms such as searching, optimization, sorting, and dynamic programming, among others.
In addition, computability and complexity (P vs NP, NP-complete problems, big-O notation, approximate algorithms, etc.), and computer architecture including memory, cache, bandwidth, deadlocks, distributed processing, etc. are also necessary for a successful machine learning engineer.
2. Data Modeling and Evaluation
Data modeling is the process by which we estimate the underlying structure of a particular dataset, with the main aim of finding useful patterns (correlations, clusters, eigenvectors, etc.) and forecasting properties of instances that were not witnesses before and include classification, regression, anomaly detection, etc.
An essential part of this estimation process is to consistently evaluate how better a given model is. While depending upon the task at hand, you will have to select an appropriate accuracy/error measure including log-loss for classification, sum-of-squared-errors for regression, etc. and also an evaluation strategy (training-testing split, sequential vs randomized cross-validation, etc.).
In addition, iterative learning algorithms can often directly utilize resulting errors for tweaking the model (e.g. backpropagation for neural networks), so having a better understanding of these measures is also very useful even for just applying standard algorithms.
3. Probability and Statistics
A machine learning engineer also needs a formal characterization of probability including conditional probability, Bayes rule, likelihood, independence, etc. as well as essential techniques derived from it such as Bayes Nets, Hidden Markov Models, Markov Decision Processes etc. that are considered key in many machine learning algorithms.
Besides, machine learning also needs a fair understanding of the field of statistics that offers various measures including mean, median, variance, etc., distributions such as uniform, normal, binomial, Poisson, etc. and also useful analysis methods such as ANOVA, hypothesis testing, etc. that are essential for building and validating successful models from observed data.
4. Application of Machine Learning Algorithms and Libraries
As far as machine learning algorithms are concerned, their standard implementations are widely available through libraries/packages/APIs (e.g. scikit-learn, TensorFlow, Theano, Spark MLlib, H2O, etc.). Still, their effective implementation involves choosing an ideally suitable model (decision tree, nearest neighbor, neural net, support vector machine, an ensemble of multiple models, etc.), a well-planned learning procedure to fit the data (linear regression, genetic algorithms, bagging, boosting, gradient descent, and other model-specific methods), and also a better understanding of how hyper-parameters can affect learning.
A machine learning engineer should also be well aware of the relative pros and cons of various approaches. The different gotchas can trip you (bias and variance, data leakage, overfitting and underfitting, missing data, etc.
5. Software Development and System Design
It all comes to the point where we expect that a machine learning engineer’s final output or deliverable is software. And often it is a small part that comes into a bigger ecosystem of products and services.
A machine learning engineer needs to understand how these various pieces work together, coordinate with them by making the most of library calls, REST APIs, database queries, etc. and create appropriate interfaces for your part that others will depend on.
It is also necessary to know that careful system design may be essential to avoid bottlenecks and allow your algorithms to scale well with enhancing volumes of data. Besides, software engineering key practices such as requirements analysis, version control, testing, documentation, system design, and modularity, to name a few are invaluable for productivity, quality, collaboration, and maintainability.
