% 30 Days of Kaggle - Day 10: (https://www.kaggle.com/dansbecker/underfitting-and-overfitting)[Over-Fitting and Under-Fitting]. Now that I can create models I need to be able to evaluate their accuracy. I calculated mean absolute error in the last notebook using sklearn. MAE = \frac{\sum_0^N | predicted - actual |}{...

# Random Walks This week we will discuss a new topic, *random walks*. Random walks are an example of a markov process, and we will also learn what this means, and how we can analyze the behavior of the random walker using a markov chain. The exercises this week are slightly more extensive then other weeks, and is mor...

## Define the Convolutional Neural Network After you've looked at the data you're working with and, in this case, know the shapes of the images and of the keypoints, you are ready to define a convolutional neural network that can *learn* from this data. In this notebook and in `models.py`, you will: 1. Define a CNN w...

# 3. Example: Univariate Gaussian ``` # Install and load deps if (!require("stringr")) { install.packages("stringr") } library(purrr) ``` As an example, we consider the heights in cm of 20 individuals: We will model the heights using the univariate Gaussian. The univariate Gaussian has two parameters, its mean...
