Career Roadmap 

To begin and advance your career as a Machine Learning Engineer, you need to follow the below-given steps-

Career roadmap

Pursue a Degree

You should pursue a bachelor's or master's degree before concentrating solely on your chosen industry in technical or analytical-related fields like:

pursue degree

  • Electrical Engineering: This field of study is focused on the engineering discipline concerned with the design, study, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism.
     
  • Computer Engineering: To prepare the graduate for developing and using technologies, as well as being able to design, produce, and manage data elaboration systems in a wide range of applications.
     
  • Mathematics/ Statistics: To prepare students to design and implement solutions to practical problems in science, engineering, and many other fields, offering two areas of emphasis.

Data Modelling

data modelling

Analyzing unstructured data models is one of a machine learning career's key responsibilities, that brings us to one more skill required which is data modeling. Having a good knowledge of data modeling is essential for every student who wants to pursue a career in machine learning. They are expected to identify patterns, analyze data structures, and evaluate the data with the help of the most suitable algorithm such as a clustering algorithm, classification algorithm, etc.

Machine Learning Algorithms 

ML Algorithms

A Machine Learning Engineer must grasp the commonly-used machine learning algorithms and know how to use them efficiently. Supervised, reinforcement, and unsupervised machine learning algorithms are the three most frequently used machine learning algorithms which are further divided into- K Means Clustering, Naive Bayes Classifier, Logistic Regression, Linear Regression, Random Forests, Decision Trees, etc. So, if you're interested to start your career in machine learning, you should have a solid understanding of these algorithms.

Projects 

Projects

After acquiring theoretical knowledge and developing the skillset essential for pursuing a career in machine learning, you should start working on some beginner-friendly projects because hands-on experience is essential. Here is the list of some projects you can start with:

  • Chatbots: Chatbots are great projects to get involved with. One can build chatbots similar to the ones integrated into many of the websites and applications we use today. Deep learning and Artificial Neural Networks can be used to develop advanced chatbots capable of answering complex questions and participating in complex conversations.
     
  • Music Recommendation System: Budding AI developers can create music recommendation systems built upon music and genre datasets. Complex recommendation systems can be built with massive datasets or open libraries and neural networks.
     
  • Sentiment and Behaviour Prediction: AI can be used for the identification of behavioral patterns and sentiments of targets. This enables sentiment or behavior prediction through the use of AI. 
     
  • Market and Stock Prediction: A good idea for artificial intelligence projects is market and stock prediction engines. This takes the data from the market into account using advanced analytics to determine the outcome of stocks or finance. 
     
  • Chess and Other Games: Developing chess with advanced AI which can act as NPC (Non-player character) is an awesome way to indulge yourself in artificial intelligence projects. This type of project is fun, and the AI developer determines the AI opponent's level of difficulty.
