Brain Weight in Humans

Variations of head sizes and brain weights in humans

Kaggle dataset obtained from this link by Anubhab Swain.

Image obtained from Matthew Butler.

Models implemented by Anne Livia.

Context

This dataset was compiled using a medical study conducted on a group of people.

Content:

This dataset shows a few variations of head sizes and masses of brains, it also consists additional gender and age group columns.

• Gender: 1 for Male, 2 for Female
• Age Range: 1 represents > 18 years of age, 2 represents < 18 years of age
• Head Size(cm^3): Head volume in cubic centimetres
• Brain Weight(grams): - Mass of brains in grams

Question to be answered:

Predict the masses of the brains using the data, and later compare it with the actual masses of brains mentioned in the dataset.

Software Information

• Python
• Pandas
• Scikit-learn
• Matplotlib
• Seaborn

Trained Models

• Linear Regression:
  • R2 (only Head Size(cm^3) considered) = 0.73
  • R2 (All three attributes) = 0.74
• Multi-layer Perceptron:
  • R2 (All three attributes) = 0.74
• Decision Tree:
  • R2 (All three attributes) = 0.69
