Question:

What is list comprehension in python?

Inactive
Harshit A.

List comprehension is a simple and elegant way of creating lists in Python. List comprehensions are not only simple but are also efficient in terms of performance. The syntax for list comprehension is one-liner: my_list_comprehension = [expression for_loop conditions] my_list_comprehension = [x**2 for x in range(20) if x%2==0 else 0]

Question:

What do you mean by the Bias-Variance tradeoff?

Harshit A.

Before going into explaining the tradeoff between bias and variance, let us explain what exactly are bias and variance and then we will see what is the tradeoff and why there is a need for it. a) Bias: As the name suggests bias is a result of wrong assumptions such as the data is linear when it is really quadratic. It leads to models underfitting the data which implies the model is not able to capture the trend of the data which leads to less accurate models. b) Variance: Variance is a result of the high sensitivity of the model towards data due to large number of features, for example, a high degree polynomial model. The models with high variance fail to generalize because of overfitting. Now, if you want to increase the complexity of the model it leads to an increase in Variance and decrease in Bias. Conversely, if you are reducing the increasing the bias, the variance is decreasing. So, you need to find a middle ground for training the model. That's why it's called a tradeoff.
