Machine learning is taking the tech industry by storm with, new advances made every day. What was once an exclusive tool has now become the mainstream in most companies and ML engineers are in high demand.
As a result, now is the perfect time to learn ML. But how do you start?
Today, we’ll help you understand this quickly evolving field to jumpstart your ML career.
Here’s what will be covered:
Artificial Intelligence (AI) and Machine Learning (ML) are two of the hottest fields in technology right now, with 71% of GeekWire Cloud Summit tech leaders saying it’s the most important technology over the next two to three years.
From healthcare and agriculture to manufacturing, energy, and retail, many companies across industries are leveraging these technologies to get ahead. In fact, the Future of Jobs survey found that 73% of companies are likely to adopt machine learning by 2022.
If you’re in search of the most in-demand and most-exciting career domains, gearing up with machine learning skills is a good move.
Virtually every industry will be looking to apply machine learning in their domain, ultimately opening up a world of opportunities for engineers to develop impactful machine learning applications.
Machine learning is also very closely related to data science, meaning that if you pursue a career in machine learning then you’ll also have the necessary skills to become a data scientist.
Employers love when you shows signs of proficiency in both because you have the foundation to analyze data, create meaning from it, and later make use of that information to train a machine learning model to predict results.
According to job site Indeed, machine learning positions have seen massive growth over the last year, up 344% from 2018. Employers are on the lookout, but the talent lacks.
This comes down to the lack of quantity and quality of candidates.
Quantity: The sourcing of candidates is incredibly difficult because the field and its applications are so nascent. Finding someone with the right experience to do a particular job is like finding a needle in a haystack.
Quality: It’s no surprise that if you have the skills to become a machine learning engineer that you’ll be picked up pretty quickly by a major company.
With big name companies swooping most of the talent, it stalls many other companies initiatives to build their data teams and usher themselves into the data-driven era.
There is a huge opportunity for software engineers to close this gap and learn the skills to become a machine learning engineer. In fact, many software engineers already have the foundation required to learn machine learning, they just don’t know it yet.
Machine learning is being used to solve a myriad of difficult problems across many industries and verticals. However, there is a common misconception among the general population that ML and AI are incredibly difficult and advanced fields, requiring robust experience in statistical analysis and calculus.
However, there are two major misconceptions that steer individuals away from machine learning:
You don’t need to learn the incredibly complex theory behind all the ML models. In the industry, 90% of projects don’t require you to build complex models. Those projects are actually data engineering, data analysis, and analyzing insights from models rather than the process of actually building models.
Companies only want to hire machine learning engineers that have academic training in machine learning. Because of the vast opportunity machine learning brings to the table, companies are going to be looking to hire engineers that have experience in software and data engineering. Meaning that as long as you can apply machine learning concepts to projects, companies aren’t going to require you to understand ML theory inside and out.
Ultimately, developers who can apply those fundamentals to new applications and spaces are going to win in the end.
Machine learning in the tech industry is pretty different from how people perceive it. Most people view it as an impenetrable field, where only a select few with years of research experience can hope to enter.
However, with the rise of popularity in the field and new frameworks to make coding models a piece of cake, there is more opportunity than ever to work on machine learning in industry.
With the necessary background, most people could probably do most industry-level machine learning tasks with just a few months of appropriate training.
The trend is abundantly clear: a majority of computer science students want to become engineers and work in industry, not pursue research or theoretical work in graduate school or beyond.
Therein lies the problem; most university and MOOC courses focus on theory rather than practical applications. Students are expected to have strong math foundations and are often tested on proofs or concepts rather than their ability to code models and apply them to real world datasets.
Even coding assignments tend to reduce practical coding value by providing curated datasets, narrowing the scope of the problem to implementing certain functions, or failing to consider model tuning and performance.
Considering data preprocessing, feature engineering, and efficient model deployment make up a majority of a machine learning engineer’s time, this is a painful oversight when it comes to preparing students for industry machine learning.
Consequently, software engineers lack the opportunity to easily gain valuable machine learning skills needed to thrive in the data-driven era. A lot of developers already have the foundation required to learn machine learning.
But advanced academic programs and courses don’t focus on the practical skills required for the majority of machine learning projects in industry.
Instead of theoretical topics and formulas, what you really should focus on are the main concepts in machine learning. An ML engineer’s job is largely centered around building models for specific tasks using frameworks like TensorFlow.
You don’t need to know the calculus behind backpropagation and gradient descent. You can just call an API function. Instead, you need to know things like which models to use for certain tasks, how they might improve training speed or model accuracy, and above all else, how to code machine learning models.
Developers should know how to utilize industry standard python frameworks — NumPy, pandas, scikit-learn, and Tensorflow to manipulate and process data and train models.
Even some of the most complicated and innovative ML models could be built relatively easily using these frameworks.
Additional concepts to explore:
Along with focusing on general machine learning concepts, you’ll want to identify what industry you want to work in, what field you want to explore (i.e. face recognition, speech, etc.) and then really understand the job’s domain.
For example, if you want to be a self-driving car engineer, you’ll definitely need to focus on image recognition and convolutional neural networks.
On the other hand, if you’re looking at a text analysis position, you’ll want to know concepts related to natural language processing.
The good news is software developers like you already have the foundation to pick up ML, and faster than you may think. Here are a few steps developers should take if they want to get into machine learning:
Have a firm grasp on data science
As a developer, if you have an interest in expanding your skills into machine learning, a large part of your role will require a foundation in data science.
You should be able to analyze data, create meaning from it, and later make use of that information to train a machine learning model to predict results.
Understand the frameworks available to you and what they’re used for
Find an industry or focus you enjoy
What interests you? Find out what you want your focus to be (i.e. image/speech recognition, etc.) and then find an industry that you really enjoy.
For example, if your focus is on image recognition and convolutional neural networks, then you may find that you’d like to work with self-driving cars.
Practical skills / concepts
Machine learning theory is important, but if you really want to kickstart your journey to become a machine learning engineer, then it’s best to focus on the practical concepts and skills that you’ll be using on a daily basis.
