### [9. Introduction to Recommender System. Part 1 (Collaborative Filtering, Singular Value Decomposition)](https://hackernoon.com/introduction-to-recommender-system-part-1-collaborative-filtering-singular-value-decomposition-44c9659c5e75)
![](https://hackernoon.com/hn-images/1*PsI17WdbeL1OUyhD5H6JMQ.png)A recommender system refers to a system that is capable of predicting the future preference of a set of items for a user, and recommend the top items. One key reason why we need a recommender system in modern society is that people have too much options to use from due to the prevalence of Internet. In the past, people used to shop in a physical store, in which the items available are limited. For instance, the number of movies that can be placed in a Blockbuster store depends on the size of that store. By contrast, nowadays, the Internet allows people to access abundant resources online. Netflix, for example, has an enormous collection of movies. Although the amount of available information increased, a new problem arose as people had a hard time selecting the items they actually want to see. This is where the recommender system comes in. This article will give you a brief introduction to two typical ways for building a recommender system, Collaborative Filtering and Singular Value Decomposition.

![](https://hackernoon.com/hn-images/1*VwDebzZpakZyXigyhCocrQ.jpeg)Recently an article by the Wall Street Journal has been floating around online that discussed <a href="https://www-wsj-com.cdn.ampproject.org/c/s/www.wsj.com/amp/articles/models-will-run-the-world-1534716720">how models will run the world</a>. I believe there is a lot of truth to that. Machine learning algorithms and models are becoming both ubiquitous and more trusted across industries. This, in turn will lead to us as humans spending less time questioning the output and simply allowing the system to tell us the answer. We already rely on companies like Google, Facebook and Amazon to inform us on ideas for dates, friends birthdays and what the best products are. Some of us don’t even think twice when it comes to the answers we receive from these companies.

It was always convenient like that until I got sudden disconnection last month. Suddenly anything stops working, and I wasted several hours hopelessly trying to fix it. When I went home, I figured out that the electricity in my apartment was very unstable due to a small construction upstairs. Of course, a simple solution is getting a UPS (Uninterruptible Power Supply), but I was fascinated by the idea that maybe I can turn on my server over the internet. That is like having the server’s power switch with me all the time. It would be so cool, especially when I’m away for an extended period and don’t want to waste money on the energy bills. This story is about how I’ve done it. You can have a look at my final network setup first.
