🖥 deepface - Python library for facial recognition and more

- pip install deepface

⏩ deepface is a lightweight Python library that allows you to find faces and analyze various attributes from photographs: age, gender, emotions.
It incorporates the best of the VGG-Face, FaceNet, OpenFace, DeepFace, DeepID, ArcFace, Dlib, SFace and GhostFaceNet models.

⏩ This is how you can compare the similarity of 2 faces, the result is in the image:

from deepface import DeepFace
result = DeepFace.verify(img1_path = "img1.jpg", img2_path = "img2.jpg")

New Data Scientists - When you learn, it's easy to get distracted by Machine Learning & Deep Learning terms like "XGBoost", "Neural Networks", "RNN", "LSTM" or Advanced Technologies like "Spark", "Julia", "Scala", "Go", etc.

Don't get bogged down trying to learn every new term & technology you come across.

Instead, focus on foundations.
- data wrangling
- visualizing
- exploring
- modeling
- understanding the results.

The best tools are often basic, Build yourself up. You'll advance much faster. Keep learning!

5 misconceptions about data analytics (and what's actually true):

❌ The more sophisticated the tool, the better the analyst
✅ Many analysts do their jobs with "basic" tools like Excel

❌ You're just there to crunch the numbers
✅ You need to be able to tell a story with the data

❌ You need super advanced math skills
✅ Understanding basic math and statistics is a good place to start

❌ Data is always clean and accurate
✅ Data is never clean and 100% accurate (without lots of prep work)

❌ You'll work in isolation and not talk to anyone
✅ Communication with your team and your stakeholders is essential

Don't stress too much on which tools to learn first.

Pickup 2-3 tools and master them. Skills are transferable.

For eg- If you can create an amazing dashboard in Power BI, you can make similar impressive dashboard in Tableau as well.

If you can run efficient queries in MySQL, it's going to be nearly same in PostgreSQL as well.

If you can manipulate fields in Excel, you can do the same stuff in Google Sheets as well.

Continuity is the key 😄

Never stop Learning ❤️

Yesterday we have posted free links to 9 courses from the most popular AI learning platforms on our WhatsApp channel.

These 9 courses covers LLMs, Agents, Deep RL, Audio and more

https://whatsapp.com/channel/0029VaoePz73bbV94yTh6V2E

To start with Machine Learning:

   1. Learn Python
   2. Practice using Google Colab
   

Take these free courses:

https://t.iss.one/datasciencefun/290

If you need a bit more time before diving deeper, finish the Kaggle tutorials.

At this point, you are ready to finish your first project: The Titanic Challenge on Kaggle.

If Math is not your strong suit, don't worry. I don't recommend you spend too much time learning Math before writing code. Instead, learn the concepts on-demand: Find what you need when needed.

From here, take the Machine Learning specialization in Coursera. It's more advanced, and it will stretch you out a bit.

The top universities worldwide have published their Machine Learning and Deep Learning classes online. Here are some of them:

https://t.iss.one/datasciencefree/259

Many different books will help you. The attached image will give you an idea of my favorite ones.

Finally, keep these three ideas in mind:

1. Start by working on solved problems so you can find help whenever you get stuck.
2. ChatGPT will help you make progress. Use it to summarize complex concepts and generate questions you can answer to practice.
3. Find a community on LinkedIn or 𝕏 and share your work. Ask questions, and help others.

During this time, you'll deal with a lot. Sometimes, you will feel it's impossible to keep up with everything happening, and you'll be right.

Here is the good news:

Most people understand a tiny fraction of the world of Machine Learning. You don't need more to build a fantastic career in space.

Focus on finding your path, and Write. More. Code.

That's how you win.✌️✌️
