There are a lot of phrases used in data science that a person would have to be a scientist to know. At its most basic level, data science is math that is sprinkled with an understanding of programming and statistics. There are certain concepts in data science that are used when analyzing the market. There are some basic data science concepts that are good to be familiar with.
Algorithms are used extensively in data science. Basically, an algorithm is a group of rules needed to perform a task. You have likely heard about algorithms being used when buying and selling stocks. Algorithmic trading is where algorithms set rules for things like when to buy a stock or when to sell a stock. For example, an algorithm could be set to purchase a stock once it drops by eight percent over the course of the day or to sell the stock if it loses 10 percent of its value compared to when it was first purchased.
Algorithms are designed to function without human intervention. You may have heard of them referred to as bots. Like robots, they make calculated decisions devoid of emotions.
We are not talking about preparing to run a 50 meter race. In machine learning and data science, training is where data is used to train a machine on how to respond. We can create a learning model. This machine learning model makes it possible for a computer to make accurate predictions based on the information it learned from the past. If you want to teach a machine to predict the future of stock prices, it would need a model of the stock prices of the previous year to use as a base to predict what will happen.
We have the data for stock prices for the last year. The training set would be the data from January to October. Then, we will use November and December as our testing set. Our machine should have learned by evaluating how the stocks worked from January through October.
Now, we will ask it to predict what should have happened in November and December of that year.
