100_days_of_ml_code_challenge icon 100_days_of_ml_code_challenge

Machine Learning is the most transformative technology of our time. Whether its helping us discover new drugs for major diseases, fighting fraud, generating music, improving supply chain efficiency, the list of applications are truly endless. I am taking up the 100 Days of ML Code as a committment to better my understanding of this powerful tool by dedicating at least 1 hour of my time everyday to studying and/or coding machine learning for 100 days.

fast-personalized-pagerank-on-mapreduce icon fast-personalized-pagerank-on-mapreduce

We will design a fast MapReduce algorithm for Monte Carlo approximation of personalized PageRank vectors of all the nodes in a graph. The basic idea is very efficiently doing single random walks of a given length starting at each node in the graph. More precisely, we design a MapReduce algorithm, which given a graph G and a length λ, outputs a single random walk of length λ starting at each node in G. We will show that the number of MapReduce iterations used by our algorithm is optimal among a broad family of algorithms for the problem, and its I/O efficiency is much better than the existing candidates. We will then show how we can use this algorithm to very efficiently approximate all the personalized PageRank vectors. Our empirical evaluation on real-life graph data and in production MapReduce environment shows that our algorithm is significantly more efficient than all the existing algorithms in the MapReduce setting.

improving-semantic-topic-clustering-for-search-queries-with-word-co-occurrence icon improving-semantic-topic-clustering-for-search-queries-with-word-co-occurrence

Uncovering common themes from a large number of unor- ganized search queries is a primary step to mine insights about aggregated user interests. Common topic model- ing techniques for document modeling often face sparsity problems with search query data as these are much shorter than documents. We present two novel techniques that can discover semantically meaningful topics in search queries: i) word co-occurrence clustering generates topics from words frequently occurring together; ii) weighted bigraph cluster- ing uses URLs from Google search results to induce query similarity and generate topics. We exemplify our proposed methods on a set of Lipton brand as well as make-up & cos- metics queries. A comparison to standard LDA clustering demonstrates the usefulness and improved performance of the two proposed methods. keywords: search queries, topic clustering, word co- occurrence, bipartite graph, co-clustering.

o2---a-semantic-search-engine icon o2---a-semantic-search-engine

O2 leverages Google’s search capabilities to implement a semantic search. The core idea in o2 is to allow a user to find documents based on the Intent within the document. For example a user may want to search for an advanced or a basic document on Java programming. The idea of “advanced” or “basic” is represented as an intent graph. A set of terms that if present in the document, reinforces the fact that the document is indeed “basic” or “advanced” in nature. In addition to intents, o2 uses a vocabulary of terms around which these indexes are to be built. For example, o2 can work with the complete set of topics, a student learns in Java and then act as a semantic search engine for these topics.
