Learn Data Science in 2025

𝟭. 𝗔𝗽𝗽𝗹𝘆 𝗣𝗮𝗿𝗲𝘁𝗼'𝘀 𝗟𝗮𝘄 𝘁𝗼 𝗟𝗲𝗮𝗿𝗻 𝗝𝘂𝘀𝘁 𝗘𝗻𝗼𝘂𝗴𝗵 📚

Pareto's Law states that "that 80% of consequences come from 20% of the causes".

This law should serve as a guiding framework for the volume of content you need to know to be proficient in data science.

Often rookies make the mistake of overspending their time learning algorithms that are rarely applied in production. Learning about advanced algorithms such as XLNet, Bayesian SVD++, and BiLSTMs, are cool to learn.

But, in reality, you will rarely apply such algorithms in production (unless your job demands research and application of state-of-the-art algos).

For most ML applications in production - especially in the MVP phase, simple algos like logistic regression, K-Means, random forest, and XGBoost provide the biggest bang for the buck because of their simplicity in training, interpretation and productionization.

So, invest more time learning topics that provide immediate value now, not a year later.

𝟮. 𝗙𝗶𝗻𝗱 𝗮 𝗠𝗲𝗻𝘁𝗼𝗿 ⚡

There’s a Japanese proverb that says “Better than a thousand days of diligent study is one day with a great teacher.” This proverb directly applies to learning data science quickly.

Mentors can teach you about how to build a model in production and how to manage stakeholders - stuff that you don’t often read about in courses and books.

So, find a mentor who can teach you practical knowledge in data science.

𝟯. 𝗗𝗲𝗹𝗶𝗯𝗲𝗿𝗮𝘁𝗲 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗲 ✍️

If you are serious about growing your excelling in data science, you have to put in the time to nurture your knowledge. This means that you need to spend less time watching mindless videos on TikTok and spend more time reading books and watching video lectures.

Data Scientists & Analysts – Let’s Talk About Mistakes!

Most people focus on learning new skills, but avoiding bad habits is just as important.

Here are 7 common mistakes that are slowing down your data career (and how to fix them):

1. Only Learning Tools, Not Problem-Solving
SQL, Python, Power BI… great. But can you actually solve business problems?

Tools change. Thinking like a problem-solver will always make you valuable.

2. Writing Messy, Hard-to-Read Code
Your future self (or your team) should understand your code instantly.

❌ Overly complex logic
❌ No comments or structure
❌ Hardcoded values everywhere

Clean, structured code = professional.

3. Ignoring Data Storytelling
You found a key insight—now what?

If you can’t communicate it effectively, decision-makers won’t act on it.

Learn to simplify, visualize, and tell a compelling data story.

4. Avoiding SQL & Relying Too Much on Excel
Yes, Excel is powerful, but SQL is non-negotiable for working with large datasets.

Stop dragging data into Excel—query it directly and automate your workflow.

5. Overcomplicating Models Instead of Improving Data
A simple model with clean data beats a complex one with garbage input.

Before tweaking algorithms, focus on:
✅ Cleaning & preprocessing
✅ Handling missing values
✅ Understanding the dataset deeply

6. Not Asking “Why?” Enough
You pulled some numbers. Cool. But why do they matter?

Great analysts dig deeper:
✅ Why is revenue dropping?
✅ Why are users churning?
✅ Why does this pattern exist?

Asking “why” makes you 10x better.

7. Ignoring Soft Skills & Networking
Being good at data is great. But if no one knows you exist, you’ll get stuck.

✅ Engage on LinkedIn/Twitter
✅ Share insights & projects
✅ Network with peers & mentors

Opportunities come from people, not just skills.

🔥 The Bottom Line?
Being a great data professional isn’t just about technical skills—it’s about thinking, communicating, and solving problems.

Time Complexity of 10 Most Popular ML Algorithms

When selecting a machine learning model, understanding its time complexity is crucial for efficient processing, especially with large datasets.

For instance,
1️⃣ Linear Regression (OLS) is computationally expensive due to matrix multiplication, making it less suitable for big data applications.

2️⃣ Logistic Regression with Stochastic Gradient Descent (SGD) offers faster training times by updating parameters iteratively.

3️⃣ Decision Trees and Random Forests are efficient for training but can be slower for prediction due to traversing the tree structure.

4️⃣ K-Nearest Neighbours (KNN) is simple but can become slow with large datasets due to distance calculations.

5️⃣ Naive Bayes is fast and scalable, making it suitable for large datasets with high-dimensional features.

6️⃣ Support Vector Machines (SVMs) – Training an SVM with a linear kernel has a time complexity of O(n²), while non-linear kernels (like RBF) can take O(n³), making them slow for large datasets. However, linear SVMs work well for high-dimensional but sparse data.

7️⃣ K-Means Clustering – The standard Lloyd’s algorithm has a time complexity of O(n * k * i * d), where n is the number of data points, k is the number of clusters, i is the number of iterations, and d is the number of dimensions. Convergence speed depends on initialization methods.

8️⃣ Principal Component Analysis (PCA) – PCA involves eigenvalue decomposition of the covariance matrix, leading to a time complexity of O(d³) + O(n * d²). It becomes computationally expensive for very high-dimensional data.

9️⃣ Neural Networks (Deep Learning) – The training complexity varies based on architecture but typically falls in the range of O(n * d * h) per iteration, where h is the number of hidden units. Large networks require GPUs or TPUs for efficient training.

🔟 Gradient Boosting (e.g., XGBoost, LightGBM, CatBoost) – Training complexity is O(n * d * log(n)) per iteration, making it slower than decision trees but highly efficient with optimizations like histogram-based learning.
Understanding these complexities helps in choosing the right algorithm based on dataset size, feature dimensions, and computational resources. 🚀
