4. Natural Language Processing (NLP)

AI can analyze unstructured data like reviews, feedback, or comments using sentiment analysis, keyword extraction, and topic modeling.

5. Pattern Recognition

AI uncovers hidden patterns, correlations, and clusters in data that traditional analysis may miss.

6. Personalization & Recommendation

AI algorithms power recommendation systems (like on Netflix, Amazon) that personalize user experiences based on behavioral data.

7. Data Visualization Enhancement

AI auto-generates dashboards, chooses best chart types, and highlights key anomalies or insights without manual intervention.

8. Fraud Detection & Risk Analysis

AI models detect fraud and mitigate risks in real-time using anomaly detection and classification techniques.

9. Chatbots & Virtual Analysts

10 Machine Learning Concepts You Must Know

1. Supervised vs Unsupervised Learning

Supervised Learning involves training a model on labeled data (input-output pairs). Examples: Linear Regression, Classification.

Unsupervised Learning deals with unlabeled data. The model tries to find hidden patterns or groupings. Examples: Clustering (K-Means), Dimensionality Reduction (PCA).


2. Bias-Variance Tradeoff

Bias is the error due to overly simplistic assumptions in the learning algorithm.

Variance is the error due to excessive sensitivity to small fluctuations in the training data.

Goal: Minimize both for optimal model performance. High bias → underfitting; High variance → overfitting.


3. Feature Engineering

The process of selecting, transforming, and creating variables (features) to improve model performance.

Examples: Normalization, encoding categorical variables, creating interaction terms, handling missing data.


4. Train-Test Split & Cross-Validation

Train-Test Split divides the dataset into training and testing subsets to evaluate model generalization.

Cross-Validation (e.g., k-fold) provides a more reliable evaluation by splitting data into k subsets and training/testing on each.


5. Confusion Matrix

A performance evaluation tool for classification models showing TP, TN, FP, FN.

From it, we derive:

Accuracy = (TP + TN) / Total

Precision = TP / (TP + FP)

Recall = TP / (TP + FN)

F1 Score = 2 * (Precision * Recall) / (Precision + Recall)



6. Gradient Descent

An optimization algorithm used to minimize the cost/loss function by iteratively updating model parameters in the direction of the negative gradient.

Variants: Batch GD, Stochastic GD (SGD), Mini-batch GD.


7. Regularization (L1/L2)

Techniques to prevent overfitting by adding a penalty term to the loss function.

L1 (Lasso): Adds absolute value of coefficients, can shrink some to zero (feature selection).

L2 (Ridge): Adds square of coefficients, tends to shrink but not eliminate coefficients.


8. Decision Trees & Random Forests

Decision Tree: A tree-structured model that splits data based on features. Easy to interpret.

Random Forest: An ensemble of decision trees; reduces overfitting and improves accuracy.


9. Support Vector Machines (SVM)

A supervised learning algorithm used for classification. It finds the optimal hyperplane that separates classes.

Uses kernels (linear, polynomial, RBF) to handle non-linearly separable data.


10. Neural Networks

Inspired by the human brain, these consist of layers of interconnected neurons.

Deep Neural Networks (DNNs) can model complex patterns.

The backbone of deep learning applications like image recognition, NLP, etc.

I can't believe people still spend hours on problem-solving when there is AI.

(And no. I'm not talking about basic problem solving)

Problem solving becomes efficient when humans and AI work together.

✅ Write a prompt
✅ Get a solution from ChatGPT
✅ Follow up and keep brainstorming till you get the best solution

Problem-solving techniques on which you can collaborate with ChatGPT:

✅ Decision Matrix: Compare options based on weighted criteria.
✅ Force Field Analysis: Analyze forces for and against a change.
✅ SWOT Analysis: Evaluate strengths, weaknesses, opportunities, and threats.
✅ First Principles Thinking: Break down complex problems to fundamental truths.
✅ MECE Principle: Organize information into mutually exclusive, collectively exhaustive categories.

I want you to act as an interviewer. I will be the
candidate and you will ask me the
interview questions for the position position. I
want you to only reply as the interviewer.

want you to only do the interview with me.
Ask me the questions and wait for my answers.
Do not write explanations. Ask me the
questions one by one like an interviewer does
and wait for my answers. My first
sentence is "Hi"
