Introducing core concepts of recommendation systems


Discover how to use Python--and some essential machine learning concepts--to build programs that can make recommendations. She helps you learn the concepts behind how recommendation systems work by taking you through a series of examples and exercises. Once you're familiar with the underlying concepts, Lillian explains how to apply statistical and machine learning methods to construct your own recommenders. She demonstrates how to build a popularity-based recommender using the Pandas library, how to recommend similar items based on correlation, and how to deploy various machine learning algorithms to make recommendations. At the end of the course, she shows how to evaluate which recommender performed the best.

Machine Learning for Building Recommender System in Python


In this article, I use the Kaggle Netflix prize data [2] to demonstrate how to use model-based collaborative filtering method to build a recommender system in Python. Recommender systems are widely used in product recommendations such as recommendations of music, movies, books, news, research articles, restaurants, etc. [1][5]. The collaborative filtering method [5] predicts (filters) the interests of a user on a product by collecting preferences information from many other users (collaborating). The assumption behind the collaborative filtering method is that if a person P1 has the same opinion as another person P2 on an issue, P1 is more likely to share P2's opinion on a different issue than that of a randomly chosen person [5]. Content-based filtering method [6] utilizes product features/attributes to recommend other products similar to what the user likes, based on other users' previous actions or explicit feedback such as rating on products.

With the growing popularity of vegan and plant-based diets, it becomes increasingly important to understand the major distinctions between the two. Here are the key diet differences that you should know about. If you've been reaching for fruits and vegetables in favor of meat and dairy during the COVID-19 pandemic, you're far from alone. A recent survey of 2,000 Americans found that more than half (57%) are eating fewer animal products since the pandemic began. WHAT IS THE DIFFERENCE BETWEEN PLANT-BASED AND VEGAN?
