Deep Learning - Crash Course 2023 - Contour Plots

The video tutorial introduces contour plots, a method for visualizing 3D data on a 2D plot. It explains how to define a 3D function and create mesh grids using NP meshgrid. The tutorial covers plotting standard contour plots with color specifications and advanced techniques like using color maps and filled contour plots. The session concludes with a brief mention of other plot types and an introduction to deep learning.

What is the primary purpose of using a contour plot?

• To visualize 3D data on a 3D plot

• To visualize 1D data on a 2D plot

• To visualize 3D data on a 2D plot

• To visualize 2D data on a 3D plot

Which function is used to create mesh grids for contour plots?

• NP meshgrid

• PLT contour

• NP linspace

• PLT plot

In a standard contour plot with a single color, how are negative values represented?

• With dashed lines

• With solid lines

• With colored lines

• With dotted lines

What does the 'cmap' argument in the PLT contour function specify?

• The color of the contour lines

• The color map for the contour lines

• The number of contour lines

• The thickness of the contour lines

What is the benefit of using a filled contour plot?

• It fills the spaces between lines with colors

• It reduces the number of lines

• It changes the plot to a 3D view

• It increases the number of contour levels
