Essential Skills For Machine Learning Engineers

Computer Science Fundamentals and Programming

The basic computer science skills required for Machine Learning Engineers include:

  • data structures (stacks, queues, multi-dimensional arrays, trees, graphs, etc.);
  • algorithms (searching, sorting, optimization, dynamic programming, etc.);
  • computer architecture (memory, cache, bandwidth, deadlocks, distributed processing, etc.);
  • computability and complexity (NP-complete problems, P vs. NP, big-O notation, approximate algorithms, etc.);

Machine Learning Algorithms and Libraries

Basic implementations of ML algorithms are widely available through different libraries, packages, and APIs (e.g., scikit-learn, Theano, Spark MLlib, H2O, TensorFlow). However, to apply them effectively, a machine learning engineer should choose a suitable model (decision tree, nearest neighbor, neural net, support vector machine, etc.) and an appropriate learning procedure to fit the data. Moreover, one should be aware of all the advantages and drawbacks of every approach to understand how it may potentially affect other processes.

Probability and Statistics

Probability (conditional probability, likelihood, independence, etc.) and various techniques derived from it (e.g., Bayes Nets, Hidden Markov Models, Markov Decision Processes, etc.) lie at the core of many machine learning algorithms.

Moreover, many machine learning algorithms are mainly extensions of statistical modeling procedures. Thus probability and statistics provide various measures (mean, median, variance, etc.), distributions (uniform, normal, binomial, Poisson, etc.) and analysis methods (ANOVA, hypothesis testing, etc.) that are necessary for building and validating models from observed data.

Data Modeling and Evaluation

On the whole, data modeling refers to the estimation of the underlying structure of a given dataset to find useful patterns like correlations, clusters, eigenvectors, etc. Data modeling is also widely used for predicting properties of previously unseen instances such as anomaly detection, regression, classification, and much more.

A professional machine learning engineer must be able to choose an appropriate accuracy/error measure and evaluation strategy (training-testing split, sequential vs. randomized cross-validation, etc.). A clear understanding of measures when applying algorithms is essential for professional ML experts. Thus continual evaluation of the given model is a vital part of the data modeling process in machine learning.

Software Engineering and System Design

An integral part Machine Learning engineer’s job is software. Oftentimes, ML engineers work on a small component which later fits into a broader ecosystem of products or services. Thus a clear understanding of how these pieces work together is crucial for building appropriate interfaces for a component that others will depend on.

Python and R are among the must-have skills for the development of machine learning models. R is mostly preferred by traditional statisticians, while the majority of machine learning engineers prefer Python due to its vast availability of libraries and open source tools.

Additionally, system design is essential for avoiding potential bottlenecks and allowing the algorithms to scale well with increasing volumes of data. What’s more, various software engineering practices such as requirements analysis, system design, modularity, version control, testing, and documentation are crucial for productivity and maintainability.

Wrap-up

All in all, an ever-growing number of companies are looking for ways to efficiently introduce machine learning into their digital strategies. It helps them have a deeper understanding of their customers, automate their processes, increase profits, and boost their overall efficiency. Thus the question of finding and choosing qualified machine learning engineers could not be more relevant.
