How Should I Feed my Gradient Descent?

Gradient Descent is always hungry for data. How should we feed the data to the gradient descent? There are three common ways to feed in data for Gradient Descent (GD): Batch, Stochastic, and Mini-Batch. Is there a best one? Why do machine learning practitioners lean towards Mini-Batch GD? We will…

Moving Beyond Linearity — ISLR Series Chapter 7

Linear Regression is a great and simple model especially adding in some regularizers. However one of the limitations of linear regression is that we are assuming that the relationship between the features and the target variables are close to linear. This is a big assumption and it is not always…

Predicting Annual Water Usage in Baltimore using ARIMA

Time Series Forecasting Walkthrough — This is a project walkthrough from the book Introduction to Time Series Forecasting with Python by Jason Brownlee. He does a great job introducing the basic topics in univariate time series and does a walkthrough at the end summarizing everything we learned. The Annual Water Usage in Baltimore dataset has…

Introduction to Time Series

Time series can be a bit difficult at first. There are new lingo that needs to be learned in addition to all the other statistical jargon. This blog explains the must-know words for time series so that we have a foundation to build on when diving deeper. Those words are…

Linear Model Selection and Regularization — ISLR Series Chapter 6

In Chapter 3, we talked about Linear Regression: how we can assume the data fits a linear model and predict using that linear model. The linear model falls short when there are a lot of features. It is good practice to collect as many data points as possible but the…

Resampling Methods — ISLR Series: Chapter 5

Now that we learned some basic models, it is time to determine how well our model performs on new data that the model has not seen before (model assessment) and how to choose the right model (model selection). The tool that is used in statistics to assess and select models…

Classification — ISLR Series: Chapter 4 — Part I

Last blog we talked about linear regression: given some data, predict a numerical response. Chapter 4 and this blog goes over the scenario when the response variable is a not a numerical value but a class. This type of machine learning is called classification. The example that ISLR uses is…

Setting up a BMP180 with the ClusterDuck Protocol

BMP180 is a great way to start learning how to integrate sensors with DuckLinks. The BMP180 are these really small sensors that collect temperature and pressure. It requires three steps: Soldering the BMP180 to a board and Uploading the firmware, and Collecting the data.

Operation Pitchfork — Deployment Analysis

On Sunday March 14, we left Brooklyn heading south to Allentown, PA. Our goal was to test the Version 2 (V2) of the ClusterDuck Protocol (CDP) which was released in Jan 2021 on a larger scale. Previously we were limited to testing the V2 in our living rooms (thanks COVID)…
