-# 🧠 **What is Logistic Regression?**
-Imagine you have a **robot** that tries to guess if a fruit is an 🍎 **apple** or a 🍌 **banana**. 
-- The robot uses **Logistic Regression** to make its guess.
-- It looks at things like the fruit’s **color**, **shape**, and **size** to decide.
-- The robot gives a score from **0 to 1**:
-    - 0 → Definitely a banana 🍌  
-    - 1 → Definitely an apple 🍎  
-    - 0.5 → The robot is unsure 🤖
-
-## 🔥 **What does the notebook do?**
-1. **Makes fake data** → It creates pretend fruits with made-up colors and sizes.
-2. **Builds the Logistic Regression model** → This is the robot that learns how to guess.
-3. **Trains the robot** → It lets the robot practice guessing until it gets better.
-4. **Shows why bad initialization is bad** → If the robot starts with **wrong guesses**, it takes a long time to learn. 
-    - Good start ➡️ 🟢 The robot learns fast.
-    - Bad start ➡️ 🔴 The robot takes forever or never learns properly.
-5. **Shows how to fix bad initialization** → We can **reinitialize** the robot with -**Random weights** to start with good guesses.
-
-
-# 🧠 **What is Cross-Entropy?**
-Imagine you are playing a **guessing game** with a 🦉 **wise owl**.  
-- The owl has to guess if a fruit is an 🍎 **apple** or a 🍌 **banana**.
-- The owl makes a **prediction** (for example: 90% sure it’s an apple).  
-- If the owl is **right**, it gets a ⭐️.  
-- If the owl is **wrong**, it gets a 👎.  
-
-**Cross-Entropy** is like a **scorekeeper**:
-- If the owl guesses correctly ➡️ **low score** 🟢 (good)  
-- If the owl guesses wrong ➡️ **high score** 🔴 (bad)  
-
-## 🔥 **What does the notebook do?**
-1. **Makes fake fruit data** → It creates pretend fruits with random colors and shapes.  
-2. **Builds the Logistic Regression model** → This is the owl’s brain that makes guesses.  
-3. **Trains the model with Cross-Entropy** → It helps the owl learn by keeping score.  
-4. **Improves accuracy** → The owl gets better at guessing with practice by trying to lower its Cross-Entropy score.
-
-
-# 🧠 **What is Softmax?**
-Imagine you have a bag of colorful candies. Each candy represents a possible answer (like cat, dog, or bird). The **Softmax function** is like a magical machine that takes all the candies and tells you the **probability** of each one being picked. 
-
-For example:
-- 🍬?->😺 **Cat** → 70% chance  
-- 🍬?->🐶**Dog** → 20% chance  
-- 🍬?->🐦 **Bird** → 10% chance  
-
-Softmax makes sure that all the probabilities add up to **100%** (because one of them will definitely be the right answer).
-
-## 🔥 **What does the notebook do?**
-1. **Makes fake data** → It creates some pretend candies (data points) to practice with.
-2. **Builds the Softmax classifier** → This is the machine that guesses which candy you will pick based on its features.
-3. **Trains the model** → It lets the machine practice guessing so it gets better at it.
-4. **Shows the results** → It checks how good the machine is at guessing the correct candy.

-# 📚 Understanding Softmax and MNIST 🖊️
-
-## 1️⃣ What are we doing?
-We want to teach a computer how to recognize numbers (0-9) by looking at images. Just like how you can tell the difference between a "2" and a "5", we want the computer to do the same!
-
-## 2️⃣ What is MNIST? 🤔
-MNIST is a big collection of handwritten numbers. People have written digits (0-9) on paper, and all those images were put into a dataset for computers to learn from.
-
-## 3️⃣ What is a Softmax Classifier? 🤖
-A **Softmax Classifier** is like a decision-maker. When it sees a number, it checks **how sure** it is that the number is a 0, 1, 2, etc. It picks the number it is most confident about.
-
-Think of it like:
-- You see a blurry animal. 🐶🐱🐭
-- You think: "It **looks** like a dog, but **maybe** a cat."
-- You decide: "I'm **80% sure** it's a dog, **15% sure** it's a cat, and **5% sure** it's a mouse."
-- You pick the one you're most sure about → 🐶 Dog!
-
-That's exactly how Softmax works, but with numbers instead of animals!
-

+# 🧠 **What is Logistic Regression?**
+Imagine you have a **robot** that tries to guess if a fruit is an 🍎 **apple** or a 🍌 **banana**. 
+- The robot uses **Logistic Regression** to make its guess.
+- It looks at things like the fruit’s **color**, **shape**, and **size** to decide.
+- The robot gives a score from **0 to 1**:
+    - 0 → Definitely a banana 🍌  
+    - 1 → Definitely an apple 🍎  
+    - 0.5 → The robot is unsure 🤖
+
+## 🔥 **What does the notebook do?**
+1. **Makes fake data** → It creates pretend fruits with made-up colors and sizes.
+2. **Builds the Logistic Regression model** → This is the robot that learns how to guess.
+3. **Trains the robot** → It lets the robot practice guessing until it gets better.
+4. **Shows why bad initialization is bad** → If the robot starts with **wrong guesses**, it takes a long time to learn. 
+    - Good start ➡️ 🟢 The robot learns fast.
+    - Bad start ➡️ 🔴 The robot takes forever or never learns properly.
+5. **Shows how to fix bad initialization** → We can **reinitialize** the robot with -**Random weights** to start with good guesses.
+
+
+# 🧠 **What is Cross-Entropy?**
+Imagine you are playing a **guessing game** with a 🦉 **wise owl**.  
+- The owl has to guess if a fruit is an 🍎 **apple** or a 🍌 **banana**.
+- The owl makes a **prediction** (for example: 90% sure it’s an apple).  
+- If the owl is **right**, it gets a ⭐️.  
+- If the owl is **wrong**, it gets a 👎.  
+
+**Cross-Entropy** is like a **scorekeeper**:
+- If the owl guesses correctly ➡️ **low score** 🟢 (good)  
+- If the owl guesses wrong ➡️ **high score** 🔴 (bad)  
+
+## 🔥 **What does the notebook do?**
+1. **Makes fake fruit data** → It creates pretend fruits with random colors and shapes.  
+2. **Builds the Logistic Regression model** → This is the owl’s brain that makes guesses.  
+3. **Trains the model with Cross-Entropy** → It helps the owl learn by keeping score.  
+4. **Improves accuracy** → The owl gets better at guessing with practice by trying to lower its Cross-Entropy score.
+
+
+# 🧠 **What is Softmax?**
+Imagine you have a bag of colorful candies. Each candy represents a possible answer (like cat, dog, or bird). The **Softmax function** is like a magical machine that takes all the candies and tells you the **probability** of each one being picked. 
+
+For example:
+- 🍬?->😺 **Cat** → 70% chance  
+- 🍬?->🐶**Dog** → 20% chance  
+- 🍬?->🐦 **Bird** → 10% chance  
+
+Softmax makes sure that all the probabilities add up to **100%** (because one of them will definitely be the right answer).
+
+## 🔥 **What does the notebook do?**
+1. **Makes fake data** → It creates some pretend candies (data points) to practice with.
+2. **Builds the Softmax classifier** → This is the machine that guesses which candy you will pick based on its features.
+3. **Trains the model** → It lets the machine practice guessing so it gets better at it.
+4. **Shows the results** → It checks how good the machine is at guessing the correct candy.
+
+
+
+# 📚 Understanding Softmax and MNIST 🖊️
+
+## 1️⃣ What are we doing?
+We want to teach a computer how to recognize numbers (0-9) by looking at images. Just like how you can tell the difference between a "2" and a "5", we want the computer to do the same!
+
+## 2️⃣ What is MNIST? 🤔
+MNIST is a big collection of handwritten numbers. People have written digits (0-9) on paper, and all those images were put into a dataset for computers to learn from.
+
+## 3️⃣ What is a Softmax Classifier? 🤖
+A **Softmax Classifier** is like a decision-maker. When it sees a number, it checks **how sure** it is that the number is a 0, 1, 2, etc. It picks the number it is most confident about.
+
+Think of it like:
+- You see a blurry animal. 🐶🐱🐭
+- You think: "It **looks** like a dog, but **maybe** a cat."
+- You decide: "I'm **80% sure** it's a dog, **15% sure** it's a cat, and **5% sure** it's a mouse."
+- You pick the one you're most sure about → 🐶 Dog!
+
+That's exactly how Softmax works, but with numbers instead of animals!
+
+## 4️⃣ How do we train the computer? 🎓
+1. We **show** the computer many images of numbers. 📸
+2. It **tries to guess** what number is in the image. 🔢
+3. If it's wrong, we **correct** it and help it learn. 📚

+
+
+## 3️⃣ What is a Hidden Layer? 🤔
+A **hidden layer** is like a smart helper inside the network. It helps break down complex problems step by step.
+

+- 🏗️ This makes it easier to recognize and understand!
+
+## 4️⃣ How do we train the computer? 🎓
+1. We **show** it some data (like numbers or pictures). 👀

+## 2️⃣ What is XOR? ❌🔄✅  
+XOR is a rule that works like this:  
+- If two things are the **same** → ❌ NO  
+- If two things are **different** → ✅ YES  
+
+Example:
