Why I Built My Own Backtester - and Why You Might (or Might Not) Want To

Outgrew Python tools, built my own Go backtester. Here's what I learned about speed, scale, and tradeoff.

Plotting Earthquakes

Plotting Earthquakes

How to plot the earthquakes on the global map. Here we will be using the historical earthquake data from USGS and plot it on the world map.

Latent Semantic Indexing - Part 2 - Indexing

This is a continuation in the series of LSI (Latent Semantic Indexing) implementation. In this post, we will walk through the implementation of creating an Index.

Latent Semantic Indexing - part 3 - Search

This is a continuation in the series of LSI (Latent Semantic Indexing) implementation. In this post, we will walk through the implementation of searching an index based on user's query.

Simple search query w.r.t. contents in the sample. Show the matching documents. Rank approximation: 35% of collection

Latent Semantic Indexing

Latent semantic indexing (LSI) provides the ability to correlate semantically related terms that could be latent in the set of documents. Latent semantic analysis allows us to see semantics in the set of documents and how we can extract meaning of the text in the documents.
