๐Ÿ”ฅ How to become a data scientist in 2025?


1๏ธโƒฃ First of all, strengthen your foundation (math and statistics) .

โœ๏ธ If you don't know math, you'll run into trouble wherever you go. Every model you build, every analysis you do, there's a world of math behind it. You need to know these things well:

โœ… Linear Algebra: Link

โœ… Calculus: Link

โœ… Statistics and Probability: Link

โž–โž–โž–โž–โž–โž–

2๏ธโƒฃ Then learn programming !

โœ๏ธ Without further ado, get started learning Python and SQL.

โœ… Python: Link

โœ… SQL language: Link

โœ… Data Structures and Algorithms: Link

โž–โž–โž–โž–โž–โž–

3๏ธโƒฃ Learn to clean and analyze data!

โœ๏ธ Data is always messy, and a data scientist must know how to organize it and extract insights from it.

โœ… Data cleansing: Link

โœ… Data visualization: Link

โž–โž–โž–โž–โž–โž–

4๏ธโƒฃ Learn machine learning !

โœ๏ธ Once you've mastered the basic skills, it's time to enter the world of machine learning. Here's what you need to know:

โ—€๏ธ Supervised learning: regression, classification

โ—€๏ธ Unsupervised learning: clustering, dimensionality reduction

โ—€๏ธ Deep learning: neural networks, CNN, RNN

โœ… Stanford University CS229 course: Link

โž–โž–โž–โž–โž–โž–

5๏ธโƒฃ Get to know big data and cloud computing !

โœ๏ธ Large companies are looking for people who can work with large volumes of data.

โ—€๏ธ Big data tools (e.g. Hadoop, Spark, Dask)

โ—€๏ธ Cloud services (AWS, GCP, Azure)

โž–โž–โž–โž–โž–โž–

6๏ธโƒฃ Do a real project and build a portfolio !

โœ๏ธ Everything you've learned so far is worthless without a real project!

๐Ÿ” Understanding Recurrent Neural Networks (RNNs) Cheat Sheet!
Recurrent Neural Networks are a powerful type of neural network designed to handle sequential data. They are widely used in applications like natural language processing, speech recognition, and time-series prediction. Here's a quick cheat sheet to get you started:

๐Ÿ“˜ Key Concepts:
Sequential Data: RNNs are designed to process sequences of data, making them ideal for tasks where order matters.
Hidden State: Maintains information from previous inputs, enabling memory across time steps.
Backpropagation Through Time (BPTT): The method used to train RNNs by unrolling the network through time.

๐Ÿ”ง Common Variants:
Long Short-Term Memory (LSTM): Addresses vanishing gradient problems with gates to manage information flow.
Gated Recurrent Unit (GRU): Similar to LSTMs but with a simpler architecture.

๐Ÿš€ Applications:
Language Modeling: Predicting the next word in a sentence.
Sentiment Analysis: Understanding sentiments in text.
Time-Series Forecasting: Predicting future data points in a series.

๐Ÿ”— Resources:
Dive deeper with tutorials on platforms like Coursera, edX, or YouTube.
Explore open-source libraries like TensorFlow or PyTorch for implementation.
Let's harness the power of RNNs to innovate and solve complex problems! ๐Ÿ’ก
