Understand the Data Science Roadmap

Learning Software Engineering or Programming

You need a strong foundation before you start your journey into data science. In either software engineering or programming, data scientists need expertise and experience. You should learn at least one programming language, such as Python, SQL, Scala, Java, or R.

Topics to Cover in Programming: Data scientists should get familiar with standard data structures, including dictionaries, lists, data types, tuples, and sets, as well as searching and sorting algorithms, control flow, logic, object-oriented programming, developing functions, and how to use third-party libraries. Aspiring data scientists should also be comfortable utilising tools connected to Git and GitHub, including version control and terminals. Last but not least, data scientists should feel comfortable using SQL programming.

Mastering Data Collection and Cleaning

It is frequently necessary to locate relevant data that resolves issues; this is where data scientists come in. They gather this data from various sources, including databases, APIs, publicly accessible data repositories, and even scraping if the site lets it.

Though rarely usable, the information gleaned from these sources. Instead, it needs to be organised and cleaned up before using tools like a multidimensional array, data frame manipulation or applying analytical and descriptive calculations. For example, to transform raw, unformatted data into information suitable for analysis, data scientists frequently employ libraries like Pandas and NumPy.

Various Projects for Data Collection

Pick a publicly available dataset, create a list of inquiries relevant to the subject matter, and then practise manipulating data with Pandas or NumPy to obtain the answers. Alternatively, collect information from a publicly accessible website or API (like Quandl, TMDB, or the Twitter API) and combine the data from many sources into a single database table or file for storage.

Learning Data Analysis and Storytelling

One major aspect of the data science roadmap is data analysis. Learning data analytics helps to analyse data to derive insights before communicating those insights to management in plain language and through clear visualisations.

Learn more Why To learn Data Science?

As they pertain to storytelling, the aforementioned responsibilities call for competency in data visualisation and good communication abilities. Additionally, you should also understand:

Business Sense: Practice posing inquiries that focus on financial indicators. Write presentations, blogs on business, and reports that are concise and easy to understand.

Dashboard Development: This involves creating dashboards that summarise or aggregate data to assist managers in making intelligent, actionable decisions using any application or specialised tools.

Preliminary Data Analysis: Defining questions, formatting, filtering, dealing with missing values, addressing outliers, and univariate and multivariate analysis are all covered in this expertise.

Learning Data Engineering

In large data-driven organisations, data engineering aids the Research and Development teams by ensuring that clean data is easily accessible for research engineers and scientists. If you want to concentrate mainly on the statistical side of things, you can skip this section, even though data engineering is an entirely distinct area.

Learn more About Learn Python For Data Science

Building effective data architectures, simplifying data processing, and sustaining sizable data systems are all duties of a data engineer. For example, to automate file system chores, create Extract/Transform/Load pipelines, and boost database processes into a high-performance resource, data engineers employ SQL, Shell (CLI), and Python/Scala tools.

Last but not least, data engineers are frequently in charge of putting these data designs into practice, which invariably calls for expertise in cloud service providers like Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

Learn Key Mathematical Concepts

A successful career in data science can be built over time by adequately understanding essential mathematical ideas, which can facilitate your learning of the subject. Statistics, linear algebra, probability, and calculus are the four fundamental concepts that form the basis of the data science roadmap. Even though statistical concepts constitute the core of every model, calculus helps with model learning and optimisation. Probability aids in predicting future events, and linear algebra is particularly valuable for extracting information from huge datasets.

Most of the emphasis on inferential and descriptive statistics is part of the data scientist roadmap, including statistical approaches. A greater grasp of how algorithms function is made possible by mathematics and statistics.

This stage of the data science roadmap majorly covers the following:

Descriptive Statistics: This entails learning about location estimates and variability.

Inferential statistics: This type of statistics encompasses the creation of business metrics, A/B testing, developing hypothesis tests, and employing confidence intervals, p-values, and alpha values to analyse gathered data and experiment results.

Single and Multivariate Calculus and Linear Algebra: Mastering these mathematical concepts helps better understand loss functions, gradients, and optimisers in Machine Learning. Calculus is a branch of mathematics that examines how to find and characterise the derivatives and integrals of functions using techniques based on adding little differences. A key component of deep learning and machine learning is the idea of gradient descent. Only those who are familiar with calculus can learn it.

Acquiring Knowledge about Machine Learning (ML) and Artificial Intelligence (AI)

The data science road map is incomplete without learning about AI and ML. Reinforcement learning, supervised learning, and unsupervised learning is the three categories under which these two segments fall.

Keep Track of Your Learning

You need a way to keep track of your progress if you're working on a lengthy, complex endeavour like mastering data science. Knowing what you've already covered, you can avoid unnecessary repetition and better visualise the next part of the data science roadmap.

Bottomline

A data science roadmap, such as the one described above, is a visual depiction of a tactical strategy intended to assist the aspiring IT professional in understanding and excelling in the discipline of data science. Enrol in the data science course immediately to upgrade your skills and kickstart or accelerate your career growth.
