Engineer in Seven StepsBuilding successful data science projects is not straightforward and sometimes it can turn into a nightmare There are many challenges from data ingestion to production including feature engineering modeling testing deployment and infrastructure management Until a few years ago data scientists were trying to deal with all these challenges on their own but they were having a hard time overcoming them To address these challenges new fields such as data engineering feature engineering and machine learning ML engineering have emerged In this blog post I ll walk you through how to become an ML engineer Here are the topics I ll cover in this post What is ML engineering Data scientist vs ML engineer vs data engineerWhat does an ML engineer do The machine project lifecycle Steps to become an ML engineer with courses and booksLet s dive in What is Machine Learning Engineering Machine learning is a modern technique for problem solving and task automation Machine learning is a subfield of AI that allows a machine to learn automatically and improve from experience without explicit instruction Building a machine learning project is a complex process that requires a range of skills from modeling to deployment and infrastructure management ML engineering emerged to bridge the gap between data science and software engineering Fortunately you can easily tackle ML engineering challenges with recently developed libraries and platforms such as Scikit Learn TensorFlow HuggingFace and Comet Data Scientist vs ML Engineer vs Data EngineerThere are three key roles in data science projects data engineer data scientist and ML engineer Data engineers create systems and pipelines that collect raw data manage it and turn it into information The data scientist theoretically creates the model prototype The ML engineer uses various tools to create the model and deploy them to production What is Machine Learning Engineering Machine learning is a modern

engineers create systems and pipelines that collect raw data manage it and turn it into information The data scientist theoretically creates the model prototype The ML engineer uses various tools to create the model and deploy them to production Let me explain these roles with an example Let s say a company wants to perform a sentiment analysis project Data engineers are responsible for properly exporting loading transforming ETL the data needed to build the model If data is continuously generated by different sources they ll build data pipelines that can transmit all this information to the right parts of the system at the right time without any delays or bottlenecks Using this data data scientists try to find the best model that predicts whether the data is positive negative or neutral ML engineers will be responsible for building the model that fits the data and deploying that model in real life as well as making sure it can perform The Machine Learning Project LifecycleThe ML lifecycle is an iterative and never ending cycle between improving data modeling and deployment This lifecycle consists of three main stages data preparation model building and model deployment Let s take a look at these stages Data PreparationReal world datasets are usually not clean These datasets are cleaned by data preprocessing Garbage in garbage out is a common concept in computer science but this concept can also be used for ML engineering if you use a clean dataset to build the model you can obtain a good model Model BuildingML engineers try to build the best model using clean data When building a model it is recommended to start with a simple model such as regression and then try complex models such as neural networks After you create the model you need to evaluate the performance of the model with various statistical metrics such as accuracy precision recall or F Model DeploymentAfter obtaining the best model it s time to deploy monitor and maintain it The purpose of the model deployment is to put the model into production So the model in production can retrieve the data and return their predicts ML engineers also are responsible for monitoring the model s performance and ensuring the model makes accurate predictions Steps to become an ML EngineerIt is a challenge to become an ML engineer After reviewing more than machine learning engineer job postings the team discovered the following skills for an ML engineer position As you can see there are many skills to become an ML engineer Let s take a closer look at the most important skills ProgrammingTo implement machine learning projects it is necessary to know a programming language The most used languages in the world of machine learning are Python and R Python is used more in data science as it is a general purpose and easy to learn language With Python you can do end to end machine projects from data cleaning to model deployment In addition many important machine learning frameworks such as Pytorch Scikit Learn and PySpark are written in Python Python Free Courses Learn Python ーFull Course for Beginners TutorialPython Tutorial ーPython Full Course for Beginners YouTube Python Books Python

be solved by deep learning techniques such as GPT and BERT based on transformers Deep learning works well with unstructured data and does not require feature engineering On the other hand deep
