ENJOY LEARNING👍👍

You won’t become an AI Engineer in a month.

You won’t suddenly build world-class systems after a bootcamp.

You won’t unlock next-level skills just by binge-watching tutorials for 30 days.

Because in a month, you’ll realize:

— Most of your blockers aren’t about “AI”, they’re about solid engineering: writing clean code, debugging, and shipping reliable software.

— Learning a new tool is easy; building things that don’t break under pressure is where people struggle.

— Progress comes from showing up every day, not burning out in a week.
So what should you actually do?

Here’s what works:

→ Spend 30 minutes daily on a core software skill.
One day, refactor old code for readability. Next, write unit tests. After that, dive into error handling or learn how to set up a new deployment pipeline.

→ Block out 3–4 hours every weekend to build something real.
Create a simple REST API. Automate a repetitive task. Try deploying a toy app to the cloud.
Don’t worry about perfection. Focus on finishing.

→ Each week, pick one engineering topic to dig into.
Maybe it’s version control, maybe it’s CI/CD, maybe it’s understanding how authentication actually works.

The goal: get comfortable with the “plumbing” that real software runs on.

You don’t need to cram.
You need to compound.
A little progress, done daily

That’s how you build confidence.
That’s how you get job-ready.

Small efforts. Done consistently.

That’s the unfair advantage you’re waiting to find, always has been.

🔍 Machine Learning Cheat Sheet 🔍

1. Key Concepts:
- Supervised Learning: Learn from labeled data (e.g., classification, regression).
- Unsupervised Learning: Discover patterns in unlabeled data (e.g., clustering, dimensionality reduction).
- Reinforcement Learning: Learn by interacting with an environment to maximize reward.

2. Common Algorithms:
- Linear Regression: Predict continuous values.
- Logistic Regression: Binary classification.
- Decision Trees: Simple, interpretable model for classification and regression.
- Random Forests: Ensemble method for improved accuracy.
- Support Vector Machines: Effective for high-dimensional spaces.

- Principal Component Analysis(PCA)

3. Performance Metrics:
- Classification: Accuracy, Precision, Recall, F1-Score, ROC-AUC.
- Regression: Mean Absolute Error (MAE), Mean Squared Error (MSE), R^2 Score.

4. Data Preprocessing:
- Normalization: Scale features to a standard range.
- Standardization: Transform features to have zero mean and unit variance.
- Imputation: Handle missing data.
- Encoding: Convert categorical data into numerical format.

5. Model Evaluation:
- Cross-Validation: Ensure model generalization.

Python Interview Questions – Part 1

1. What is Python?
Python is a high-level, interpreted programming language known for its readability and wide range of libraries.

2. Is Python statically typed or dynamically typed?
Dynamically typed. You don't need to declare data types explicitly.

3. What is the difference between a list and a tuple?

List is mutable, can be modified.

Tuple is immutable, cannot be changed after creation.


4. What is indentation in Python?
Indentation is used to define blocks of code. Python strictly relies on indentation instead of brackets {}.

5. What is the output of this code?

x = [1, 2, 3]
print(x * 2)

Answer: [1, 2, 3, 1, 2, 3]

6. Write a Python program to check if a number is even or odd.

num = int(input("Enter number: "))
if num % 2 == 0:
print("Even")
else:
print("Odd")

7. What is a Python dictionary?
A collection of key-value pairs. Example:

person = {"name": "Alice", "age": 25}

8. Write a function to return the square of a number.

def square(n):
return n * n
