5 Steps for beginners to learn Machine learning and Data-Science in Python

Explore

Start with the basics:

It is important to have a good understanding of mathematics (especially linear algebra and probability) and computer science (especially programming and data structures) before diving into machine learning and data science.

Choose a focus:

There are many different areas within machine learning and data science, such as natural language processing, computer vision, and time series analysis. It can be helpful to choose a specific area to focus on initially.
With so many different areas of machine learning and data science, it can be difficult to decide which one to focus on. Natural language processing, computer vision, and other areas all have their own unique challenges and opportunities. It is important for aspiring data scientists to take the time to research each area thoroughly before deciding which one they want to focus on.
By researching the various areas within machine learning and data science, you can gain a better understanding of the skills needed for each area. Additionally, you can also find out what kind of projects are available in each area that you may be interested in pursuing. Once you have decided on an area of focus, you will then be able to begin honing your skills in that particular field.

Learn the tools of the trade:

Python, R, and TensorFlow are some of the most popular tools and frameworks used in the field of machine learning and data science.
Python is a general-purpose programming language that is widely used for data analysis and scientific computing.
R is a programming language and software environment specifically designed for statistical computing and graphics.
TensorFlow is an open-source machine learning framework developed by Google.
These tools are commonly used for tasks such as data preprocessing, visualization, and building and training machine learning models. It is important for professionals in the field to become proficient in at least one of these tools in order to be able to effectively perform data analysis and build machine learning models.

Practice on real-world data:

Working with real-world data is an important part of learning machine learning and data science. Real-world data is often messy and can be difficult to work with, as it may be incomplete, noisy, or have other types of issues. By practicing with real-world data, you can learn how to clean and preprocess data, how to identify and handle problems such as missing values, and how to apply appropriate machine learning techniques to the data. This can help you develop the skills and knowledge necessary to effectively perform data analysis and build machine learning models in a variety of different contexts.
​

Keep learning:

The field of machine learning and data science is constantly evolving, with new techniques and technologies being developed all the time. It is important to stay up-to-date and continue learning in order to keep your skills sharp.

  1. Are you a software developer, scientist or engineer?
  2. Are you a graduate student who wants to start a career in data science?
  3. Or are you a manager who wants to upskill the company workforce?
    Then Beyond Machine is for you. Beyond Machine combines the best practices from MOOCs, bootcamps and university courses into a unique program that blends online and classroom learning.
    Inside this course, I’ve put all my 10+ years of experience in data science. The result is something that combines depth, breadth and flexibility, in a price that can’t me matched. The reason we offer this price is because we are not a huge corporation, but we keep small groups of students, focusing on quality over quantity.
    The program also includes personalised mentoring by me, as well as assistance in getting a job.
