The Bias—Variance Dilemma: Why Imperfection is the Key to Better Models
- Bias is the difference between the model’s predicted and actual values, indicating systematic errors due to simplistic assumptions.
- High bias leads to underfitting, where the model does not capture the complexity of the data well and performs poorly on training and testing sets.
- Low bias signifies the model accurately fits the training data by capturing underlying patterns and relationships.
- Illustration: Trying to fit curve-shaped data points with a straight line leads to a simplistic model that misses most of the data points, showcasing the impact of bias-variance dilemma.

Can machines be given consciousness?
- Consciousness is a non-physical quality that consists of a continuum of awareness and feeling.
- David J. Chalmers highlights that there is more to consciousness than mere computation with MRI-scanned brains.
- Creating a human-like body for robots is easier than replicating consciousness, which is not reducible to computation.
- The materialist approach to the mind struggles to explain abstract thought and traditional models do not fully explain consciousness.
