6. Neiro’s AI Learning Challenges
Welcome to Neiro’s AI Learning Challenges, where learners of all levels can test their skills and creativity in real-world scenarios.
These beginner-friendly exercises are designed to provide hands-on experience in working with artificial intelligence tools, fostering an environment of exploration and growth. Whether you're new to AI or looking to enhance your knowledge, these challenges offer engaging ways to learn and apply concepts.
Challenge 1: Train an AI Model to Classify Images of Fruits
This challenge introduces the basics of training a machine learning model by classifying images of apples and bananas.
Objective: Build a simple image classification model that identifies whether an image contains an apple or a banana.
Steps to Complete:
Gather Data:
Collect a dataset of apple and banana images. Use online resources or free datasets like Kaggle or Google Dataset Search.
Select a Tool:
Use a beginner-friendly platform such as Google’s Teachable Machine or TensorFlow Lite Model Maker.
Preprocess Data:
Ensure all images are resized to a consistent format (e.g., 128x128 pixels) and split into training and testing sets.
Train the Model:
Upload your dataset and train a neural network using the selected tool. Adjust training parameters like epochs and batch size for optimal results.
Test the Model:
Evaluate its accuracy using your testing dataset. Experiment with new images to see how well the model performs.
Outcome: A functional AI model capable of differentiating between apples and bananas with a high degree of accuracy.

Challenge 2: Create a Gesture-Recognition Model with Teachable Machine
Dive into the world of computer vision by building a model that recognizes simple hand gestures.
Objective: Develop a gesture-recognition system that can identify hand signals, such as thumbs up, peace signs, or open palms.
Steps to Complete:
Access Teachable Machine:
Visit Teachable Machine, Google’s no-code AI training platform.
Capture Gesture Data:
Use your webcam to record examples of different hand gestures. Aim for at least 30 images per gesture to ensure accuracy.
Train the Model:
Train the model on the captured images, assigning labels to each gesture.
Export and Test:
Export the trained model and test it with live gestures to confirm its accuracy.
Implement in an Application:
Integrate the model into a basic web app using JavaScript, allowing users to interact with it.
Outcome: A working model that recognizes specific hand gestures and responds in real time.
Neiro’s Tip: "AI models are like students—they learn best when the teacher (you) provides clear examples!"
Challenge 3: Build a Text Summarizer with Hugging Face
Step into natural language processing (NLP) by creating a basic text summarizer for news articles.
Objective: Use pre-trained models from Hugging Face to condense lengthy news articles into concise summaries.
Steps to Complete:
Set Up the Environment:
Install the Hugging Face library in Python (
pip install transformers).
Select a Pre-Trained Model:
Choose a summarization model such as T5 or BART from Hugging Face’s model hub.
Write the Code:
Create a Python script that:
Loads the pre-trained model.
Accepts a news article as input.
Outputs a summarized version of the text.
Test the Summarizer:
Input various articles and compare the summaries with the original text to ensure clarity and accuracy.
Refine the Model:
Fine-tune the pre-trained model on custom datasets for improved performance in specific contexts.
Example Code:
pythonCopiar códigofrom transformers import pipeline
# Load pre-trained summarization model
summarizer = pipeline("summarization")
# Input news article
article = """
Artificial Intelligence (AI) has been making waves in various industries...
"""
# Generate summary
summary = summarizer(article, max_length=50, min_length=25, do_sample=False)
print("Summary:", summary[0]['summary_text'])Outcome: A functional summarization tool that extracts key points from lengthy texts, making it ideal for news readers.
