Working in finance, I’m somewhat bummed that I don’t often get to explore the possibilities within location-based data.

Expand Your Predictive Palette III.I: Sales Forecast with Prophet Tool

At a high-level, forecasting techniques can be broken down into three main categories:

Historical Average with Sliding Windows

Examples: Seasonal Decomposition, Exponential Smoothing (ETS)
Pros: Simplicity: any tool can integrate like Excel & Tableau;
Cons: Laggardly reaction to changes & overly responsive with outliers, only works with simple structure

Linear Models

Examples: ARIMA, VAR(Good for multiple time series)
Pros: Works with consistent variation, such as established seasonality trends
Cons: Proper assumption on stationarity and homoscedasticity (statistics term for consistent variance/error). Careful predictor selection to prevent multicollinearity (statistics term when predictors are linearly correlated).

Non-Linear Models

Examples: Prophet, GARCH (generalized autoregressive conditional heteroskedasticity), Deep Learning
Pros: Discovering non-linear relationship & data drift in your data.

Analytics as an Equalizer: Creating a “We Culture”

Everything starts with a story. There was a time, not too long ago, when it was incredibly rare to see women pursue careers in science and technology and while we still see women underrepresented in these areas, women are taking a stronger foothold in mathematics and analytics.

What is Feature Engineering?
First, before we go too far into all the reasons why we are excited, let’s talk a bit about what Feature Engineering is all about.

Expand Your Predictive Palette II: Beyond K-Means

After enriching our supervised learning palette, folks asked: How about an unsupervised technique like clustering or dimension reduction?

Indeed, a common data science statistic is that 80% of our work is data preparation; one of our common tasks is to group the data points into various clusters with similar properties and characteristics.
