Tips to Make the Most of Your ML Projects

• Start with clean datasets. Look for beginner-friendly ones on Kaggle or UCI.
  
• Understand your data before modeling. Explore it deeply using visualizations.
  
• Try different algorithms. See what works best—every dataset behaves differently!
  
• Document everything. Create Jupyter notebooks or GitHub repos to showcase your work.
  
• Explain your process. Write a blog or make a YouTube video to explain your project.

Common Mistakes Beginners Make in ML Projects

Even the best machine learning projects for beginners can go wrong if you’re not aware of these pitfalls:

1. Skipping Data Cleaning

Messy data = bad models. Spend time handling:

• Null values
  
• Outliers
  
• Wrong data types
  
• Duplicates

2. Using Accuracy Alone as a Metric

Especially with imbalanced datasets, accuracy can be misleading. Also check:

• Precision & Recall
  
• ROC AUC Score
  
• Confusion Matrix

3. Overfitting the Model

If your model does well on training data but badly on test data—it’s overfitting. Use regularization or reduce model complexity.

4. Not Documenting Work

Keep notes on:

• What models you tried
  
• What hyperparameters you used
  
• What worked and didn’t

It’ll help later when revisiting the project or explaining it to someone else.

5. Giving Up Too Early

Projects can feel tough at times. If something breaks, take a break—but come back to it. Every bug is a learning opportunity.
