What is RAG? 🤖📚

RAG stands for Retrieval-Augmented Generation.
It’s a technique where an AI model first retrieves relevant info (like from documents or a database), and then generates an answer using that info.

🧠 Think of it like this:
Instead of relying only on what it "knows", the model looks things up first - just like you would Google something before replying.

🔍 Retrieval + 📝 Generation = Smarter, up-to-date answers!

Google published a 150-page report on Health AI Agents - 7,000 annotations, 1,100+ hours of expert work.

But the main thing is not the metrics, but the new design philosophy.

Instead of a monolithic *"Doctor-GPT"*, Google is creating a Personal Health Agent (PHA) - a system of three specialized agents:
- Data Science Agent - analyzes wearable devices and lab data
- Domain Expert Agent - verifies medical facts and knowledge
- Health Coach Agent - conducts dialogue, sets goals, adds empathy

🧩 Everything is connected by an orchestrator with memory: user goals, barriers, insights.

⚡️ Results
- Outperformed baseline models on 10 benchmarks
- Users preferred PHA over regular LLMs (20 participants, 50 personas)
- Experts rated answers 5.7–39% better on complex medical queries

⚙️ Design principles
- Consider all user needs
- Adaptively combine agents
- Do not ask for data that can be inferred
- Minimize latency and complexity

🧠 Tested scenarios
- General health questions
- Data interpretation (wearables, biomarkers)
- Advice on sleep, nutrition, activity
- Symptom assessment (without diagnosis)

⚠️ Limitations and future
- Slower than single agents (244 s vs. 36 s)
- Need bias audits, data protection, and regulatory compliance
- Next step - adaptive communication style: empathy ↔️ responsibility

💡 Conclusion
Google shows the way forward: not a "super doctor bot," but modular, specialized agent teams.
Medicine is just the first test. Next: finance, law, education, science.

💠 The Best Tool for Extracting Data from PDF Files!

👩🏻‍💻 Usually, PDF files like financial reports, scientific articles, or data analyses are full of tables, formulas, and complex texts.

⬅️ Most tools only extract texts and destroy the data structure, causing important information to be lost.

But the tool Docling uses artificial intelligence to preserve all those structures (text, tables, formulas) exactly as they are in the file. Then it converts that data into a structured format. Meaning AI models can work on them.

The interesting point is that with just three lines of Python code, you can convert any PDF into searchable data!

🔰 Create a Pencil Sketch Filter in Python ✏️

A quick guide to image processing with OpenCV (CV2).

The Pipeline:
Original Image → Grayscale → Inverted Image → Blurred Invert → Final Sketch

By blending the grayscale and blurred invert layers, we simulate the effect of a hand-drawn sketch. A simple yet powerful technique!


Ideal for beginners looking to dive into computer vision.

# Importing the Required Moduel
# pip install opencv-python
import cv2 as cv

# Reading the image
# Replace this image name to your image name
image = cv.imread("avatar.jpg")

# Converting the Image into gray_image
gray_image = cv.cvtColor(image, cv.COLOR_BGR2GRAY)

# Inverting the Imge
invert_image = cv.bitwise_not(gray_image)

# Blur Image
blur_image = cv.GaussianBlur(invert_image, (21,21), 0)

# Inverting the Blured Image
invert_blur = cv.bitwise_not(blur_image)

# Convert Image Into sketch
sketch = cv.divide(gray_image, invert_blur, scale=256.0)

# Generating the Sketch Image Named as Sketch.png
cv.imwrite("Sketch.png", sketch)
