Day 15: Backtest II

November 7, 2024 | OSM

On Day 14 we showed how the trading model we built was snooping and provided one way to correct it. Essentially, we ensure the time in which we actually have the target variable data aligns with when the trading signals are produced. We then used th...

How to conditionally format a scatterplot in Excel

November 6, 2024 | George Mount

A scatterplot is a chart that displays the relationship between two variables by plotting data points along the X and Y axes, with each point representing a unique pair of values. By conditionally formatting points based on their category, we can reveal patterns, clusters, or outliers, making it easier to ...

How to Implement KNN with RBF Metric in Machine Learning

November 6, 2024 | Andrea Rekasi

K-Nearest Neighbours algorithm doesn’t deal very well with high-dimensional data and complex decision boundaries. Data points’ meaningful relationships often escape traditional distance metrics, which results in suboptimal classification. KNN with RBF metric solves these limitations by changing the feature space into a better format for similarity calculations. Our readers ...

Day 14: Snooping

November 6, 2024 | OSM

Guess what? The model we built in our last post actually suffers from snooping. We did this deliberately to show how easy it is to get mixed up when translating forecasting models into trading signals. Let’s explain. Our momentum model uses a 12-wee...

Day 13: Backtest I

November 5, 2024 | OSM

Unlucky 13! Or contrarian indicator? There’s really nothing so heartwarming as magical thinking. Whatever the case, on Day 12 we iterated through the 320 different model and train step iterations to settle on 10 potential candidates. Today, we look ...

How to Annotate Patent Webpages for Enhanced Research and Analysis

November 4, 2024 | Andrea Rekasi

Patent research just needs careful attention to detail and systematic documentation. Researchers, patent attorneys, and IP professionals now find webpage annotations crucial to quickly extract, analyze, and share critical information. Knowing how to mark up, highlight, and comment on patent documents directly boosts research accuracy and makes the analysis process ...
