Event Recommendation Engine Challenge was my second challenge at Kaggle and I finished 15th out of 225 on final (private) leaderboard. I was able to finish 1st on public leaderboard. Believe or not but the difference doesn’t come from over fitting but rather from an external data source (Google Maps) which was forbidden. I did read the rules, but such important restriction was buried under additio

【レビュー】「お勧め」機能が新しいフィードリーダー「SocialFeed」を体験 (1) SearchからRecommendationへの流れ | ネット | マイコミジャーナル
SocialFeedとは? リアルコムが11日にβ版サービスを開始したWebアプリケーション「SocialFeed」は、「ユーザの嗜好」に焦点を当て、「レコメンデーション(お勧め)」機能を前面に押し出した、新しいコンセプトのフィードリーダーだ(「フィード」というのはRSSやAtomなどのこと)。 このサイトによって「お勧め」されるものは、もちろん、フィードによって配信される記事情報だ。つまり、サイトが「この記事はいかがですか?」とユーザに提案してくるというわけだ。気になるのは、その「お勧め」が実際、的を射たものかどうかという点。つまり、SocialFeedはお勧めする記事をどう判定しているのだろうか、というのが問題だ。 説明によればSocialFeedは、ユーザが読んだ記事の履歴を元に、似た嗜好のユーザを探し出し(これを「隠れたコミュニティ」と呼ぶ)、それらのユーザが同じく興味を持ち、多く
“You might be interested in red toilet paper, because you bought blue and green toilet paper, and people who also bought blue and green toilet paper tend to also buy red toilet paper”. Recommendation engines are now everywhere, from e-commerce to social networks. Graphs databases like Neo4j are probably the best way to tackle the problem. But as an alternative, let’s try building a recommendation
In this chapter, we will use MLlib to make personalized movie recommendations tailored for you. We will work with 10 million ratings from 72,000 users on 10,000 movies, collected by MovieLens. This dataset is pre-loaded in your USB drive under data/movielens/large. For quick testing of your code, you may want to use a smaller dataset under data/movielens/medium, which contains 1 million ratings fr

Deep Transfer Learning for Search and Recommendation The WEB Conference 2020 Tutorial
Training data sparsity is a common problem for many real-world applications in Search and Recommendation domains. Even for applications with a lot of training data, in the cold-start scenario we usually do not get enough labeled data. Transfer Learning is a promising approach to address this problem by bridging the generalization gap from the related applications into the new one. With the increas

Netflix provides personalized recommendations at scale to over 37 million members across 40 countries. They take a multi-layered approach using offline, nearline, and online computation. In the offline layer, large datasets are processed to train machine learning models. The nearline layer incrementally refines recommendations based on member events. In the online layer, recommendations are genera
The profusion of online news articles makes it difficult to find interesting articles, a problem that can be assuaged by using a recommender system to bring the most relevant news stories to readers. However, news recommendation is challenging because the most relevant articles are often new content seen by few users. In addition, they are subject to trends and preference changes over time, and in

Research into recommender systems took off with the Netflix challenge, which started in 2006. For three years many contenders worked hard to achieve the prescribed error threshold. Finally, in 2009 Netflix awarded the prize, one million dollars. Kaggle is a direct descendant of that formula. Define the problem, provide some data, choose the evaluation metric, optionally arrange for a prize, go. Wo
