Machine learning is a rapidly growing field that has revolutionized the way we interact with technology. From virtual assistants and self-driving cars to fraud detection and medical diagnosis, machine learning is transforming every industry and sector, and it’s showing no signs of slowing down.
In 2022, the machine learning market was valued at $21.17 billion — up from $15.44 billion the year prior. And as more organizations embrace the capabilities of machine learning, that number is expected to grow to $209.91 billion by 2029.
This growth has also spurred increased demand for machine learning skills, creating a massive opportunity for tech professionals to apply their knowledge in innovative new ways. But the skills needed to thrive in machine learning are, like the industry itself, ever evolving.
To succeed in this fast-paced and exciting field, it’s essential to master these eight key skills and stay up to date with the latest developments.
1. Deep Learning
Deep learning is a type of machine learning that involves training deep neural networks with many layers to learn complex patterns in data. In 2023, deep learning skills will be more important than ever as the demand for AI applications continues to grow. Industries such as healthcare, finance, and e-commerce are already leveraging deep learning to improve their products and services, with applications ranging from disease detection to portfolio management to personalized product recommendations.
Some popular deep learning frameworks include TensorFlow, PyTorch and Keras. Learning how to use these frameworks to build and train deep neural networks gives candidates a competitive edge in the job market.
2. Natural Language Processing (NLP)
Natural Language Processing (NLP) is a field of study that involves teaching computers to understand human language. With the meteoric rise of OpenAI’s natural language processing tool ChatGPT as well as significant growth among the NLP market as a whole, we’ve seen a surge in interest in this technology — as well as demand for professionals who know how to harness it.
NLP involves techniques such as sentiment analysis, named entity recognition and language translation, the results of which are then used to power services like virtual assistants, automated customer service and content analysis. Given its broad applications, learning how to apply NLP techniques to real-world problems will be a valuable skill in any machine learning professional’s toolkit.
3. Embedded Machine Learning
Embedded machine learning involves deploying machine learning models on resource-constrained devices such as sensors, smartphones and IoT devices. With the growth of the Internet of Things and the increasing use of AI in mobile applications, embedded machine learning is becoming a crucial skill for machine learning professionals in 2023.
Embedded machine learning has several advantages, such as faster decision-making, reduced latency, and improved privacy and security. For example, embedding machine learning models on sensors can enable real-time data analysis and decision-making, without the need for cloud connectivity.
To master embedded machine learning, it’s important to learn how to build and optimize machine learning models for deployment on edge devices. This involves techniques such as model quantization, pruning and compression, which are used to reduce the size and complexity of machine learning models while maintaining their accuracy and performance.
Furthermore, it’s helpful to have a good understanding of the hardware and software architectures of edge devices, as well as the constraints and limitations of these devices. This allows machine learning professionals to design and implement efficient and optimized machine learning pipelines that can run on edge devices.
4. Data Preparation
Data preparation is the process of cleaning, transforming and formatting data so that it can be used for machine learning. And given the ever-growing volume of data being generated and used today, data preparation skills are crucial.
Data preparation involves tasks such as data cleaning, feature engineering and data augmentation, which are essential for building accurate and reliable machine learning models. Understanding how to prepare data for machine learning and how to leverage tools like pandas, NumPy and scikit-learn will be a valuable skill in 2023.
5. Strong Coding Skills
Building, testing and deploying machine learning models is a complex process that requires a strong set of coding chops. In 2023, professionals who can write clean, efficient and scalable code will be highly sought after.
Having a solid foundation in programming concepts such as data structures, algorithms and object-oriented programming is important for machine learning professionals. Python, Java, R and C++ are currently some of the most popular languages used in machine learning, but it’s worth keeping an eye on emerging languages like Julia and Kotlin too.
Additionally, as machine learning models become more complex and require more computational resources, the ability to optimize code for performance becomes increasingly important. This involves techniques such as parallelization, vectorization and GPU acceleration, which can significantly speed up the training and inference of machine learning models.
6. Advanced Statistics and Mathematics
In machine learning, statistics and mathematics form the backbone of the algorithms used to make predictions and decisions. As such, understanding the advanced concepts of statistics and mathematics is a crucial skill to have. This includes topics like probability theory, linear algebra and calculus.
Understanding these concepts enables machine learning engineers and data scientists to develop more complex and sophisticated models that can handle more significant amounts of data. Having a strong grasp of these concepts is also essential for debugging and troubleshooting machine learning models.
7. Cloud Computing
Cloud computing involves the delivery of computing services, including storage, processing and analytics, over the internet. In recent years, cloud computing has become an integral part of the machine learning landscape, and it will continue to play an important role in 2023.
Using cloud-based machine learning services such as Amazon SageMaker, Google Cloud ML Engine and Microsoft Azure Machine Learning can help organizations scale their machine learning projects and reduce costs. Additionally, learning how to deploy machine learning models on the cloud using platforms like AWS Lambda or Azure Functions will be an essential skill in 2023.
Furthermore, cloud computing enables the creation of hybrid and multi-cloud solutions that combine on-premise and cloud-based infrastructure. This allows organizations to take advantage of the best features of different cloud providers and build more flexible and scalable machine learning pipelines.
8. Domain Knowledge
In 2023, having domain knowledge in a particular field can be an incredibly valuable asset in a machine learning engineer. Domain knowledge refers to a deep understanding of a specific industry or business, such as healthcare, finance or cybersecurity.
Having domain knowledge allows machine learning professionals to better understand the nuances of the data they’re working with, identify potential problems and biases, and develop models that are tailored to specific industry needs. This knowledge will be critical for professionals who want to develop custom solutions that are highly effective in their respective fields.
