What you'll learn

  • Designing and maintaining data systems and databases; this includes fixing coding errors and other data-related problems. Mining data from primary and secondary
  • Data Acquisition, Data Entry, Signal Reception, Data Extraction. This stage involves gathering raw structured and unstructured data.
  • 1. Machine learning is the backbone of data science. Data Scientists need to have a solid grasp of ML
  • 5 Different Practical Data Science projects with ipython Notebooks

Course content

13 sections292 lectures31h 18m total length
  • video12:54

    Explore the foundations and basics of probability and combinatorics, and apply them to data science, machine learning, and optimization through random experiments, outcomes, events, and uncertainty.

  • video23:38

    Explore sample space and events, outcomes from coin flips and card draws, and learn to calculate probabilities, including independent events with P(A∩B) = P(A)P(B).

  • video33:30

    Learn combinatorics basics, including counting, selecting, and the difference between permutations and combinations, and explore vectors vs scalars with magnitude and direction.

  • video46:56

    Learn vector operations—addition, subtraction, scalar multiplication, and dot and cross products—using geometric and algebraic methods to obtain resultant vectors. Apply to physics, combinatorics-based probability, and 3d graphics.

  • video57:11

    Explore probability basics and combinatorics through Python coding in Google Colab, covering sample space, events, independent events, combinations, permutations, vectors, and data frames for probability distributions.

  • video63:07

    Explore the role of statistics in data science and how statistical bias drives systematic errors in estimation. Understand unbiased estimations and how biases appear in surveys, medical trials, hiring.

  • video78:28

    Explore how sampling bias and data selection affect results, and learn bias mitigation techniques like randomization, blinding, and transparent reporting, plus how mean, median, and mode summarize data.

  • video89:37

    Explore noise in regression analysis and the error term that explains differences between predicted and actual values. Learn regularization techniques—L1, L2, and elastic net—to improve generalization and prevent overfitting.

  • video96:59

    Explore statistical bias, noise in data, central tendency, and regularization in linear regression using numpy, pandas, scikit-learn, and matplotlib, with sample datasets and visualizations.

  • video1040:34

    Analyze distributions using histograms, box plots, and cdf plots. Learn to detect outliers, impute missing values, and apply correlation and covariance in Python.

Requirements

  • There is no specific prerequisite to learn machine learning. But you need to be from engineering/science/Maths/Stats background to understand the theory and the techniques used. You need to be good in mathematics. If you are not, still you can machine learning, but you will face difficulty when solving complex real world problems. Many say you need to know Linear algebra, Calculus etc. etc. but I never learnt it, yet I am able to work on machine learning.

Description

Why Data Science? (Decide the Goal First?)

So before jumping into the complete Roadmap of Data Science one should have a clear goal in his/her mind that why he/she wants to learn Data Science? Is it for the phrase “The Sexiest Job of the 21st Century“? Is it for your college academic projects? or is it for your long-term career? or do you want to switch your career to the data scientist world? So first make a clear goal. Why do you want to learn Data Science? For example, if you want to learn Data Science for your college Academic projects then it’s enough to just learn the beginner things in Data Science. Similarly, if you want to build your long-term career then you should learn professional or advanced things also. You have to cover all the prerequisite things in detail. So it’s on your hand and it’s your decision why you want to learn Data Science.

How to Learn Data Science?

Usually, data scientists come from various educational and work experience backgrounds, most should be proficient in, or in an ideal case be masters in four key areas.

  1. Domain Knowledge

  2. Math Skills

  3. Computer Science

  4. Communication Skill

Domain Knowledge

Most people thinking that domain knowledge is not important in data science, but it is very important. Let’s take an example: If you want to be a data scientist in the banking sector, and you have much more information about the banking sector like stock trading, know about finance, etc. so this is going to be very beneficial for you and the bank itself will give more preference to these type of applicants more than a normal applicant.

Math Skills

Linear Algebra, Multivariable Calculus & Optimization Technique, these three things are very important as they help us in understanding various machine learning algorithms that play an important role in Data Science. Similarly, understanding Statistics is very significant as this is a part of Data analysis. Probability is also significant to statistics and it is considered a prerequisite for mastering machine learning.
