While cleaning my hard drive, I stumbled upon my very first Data Science project. I implemented a recommander system for a website using Collaborative Filtering. It was fascinating and frustrating at the same time as I was struggling for a several weeks, trying to wrap my head around the techniques like Stochastic Gradient Descent and Alternative Least Square. Looking back, I have come quite a long way in 1 year. However, many exciting things are still waiting for me ahead, and I can’t wait to face my next challenge!
Recommender system: article. Enjoy!
