We often do not need to look at all the contents of a data frame in the console. Instead, only parts of it are sufficient like the top or bottom retrieved through the head() and tail() functions. Select the top of a data frame Select the bottom of a ...

In our last post, we compared the three most common methods used to set return expectations prior to building a portfolio. Of the three—historical averages, discounted cash flow models, and risk premia models—no single method dominated the others on...

Introduction Active funds have done poorly over the last ten years, and in most cases, struggled to justify their fees. A growing list of commentators appropriately advocate for index funds, although sometimes go a little beyond what we believe to be fairly representing the facts. The inspiration for this article ...

Intro When we create bounding boxes in images, particularly if we intend to feed them into predictive models for object localization and classification, we are often: Processing many images Classifying the contents of the bounding boxes Standardizing the size of the images Capturing the coordinates The boundingbox package v1.0.1 ...

In our last post, we compared the three most common methods used to set return expectations prior to building a portfolio. Of the three—historical averages, discounted cash flow models, and risk premia models—no single method dominated the others on average annual returns over one, three, and five-year periods. ...

I had to ingest some medium to high volume data from official French government sites, and would like to share my return on experience. Data ingestion here is solved globally, without any other consideration than maximum reduced time for implement...

Recently you might have seen an interesting ABC piece on Dustin Martin In it it features some graphs built using data that has just recently become available in fitzRoy thanks to fryziggg who has kindly made it available for fans of afl statistics everywhere. So what are the new things, ...

In this tutorial I will discuss on how to use keras package with tensor flow as back end to build an anomaly detection model using auto encoders. Auto encoders is a unsupervised learning technique where the initial data is encoded to lower dimensional and then decoded (reconstructed) back. Based on ...
