In this notebook we look at changes in surface temperature of areas around the world from 1961-2020 using a dataset from the Food and Agriculture Organization of the United Nations. The changes in temperature are with reference to a baseline climatology found within the reference period of 1951-1980. Thereafter, we will attempt to forecast temperature changes using two popular techniques.

In this notebook we will be using an autoencoder on the fraud dataset used in a previous notebook for novelty detection. Novelty detection refers to the identification of new or unknown signals not available to a machine learning system during training. In this case it refers to training a machine learning model only on normal(non-fradulent) transactions data but the resultant model has the ability to recognise fraudulent transactions.
