Closing the Sale: Predicting Home Prices via Linear Regression

Imports, Data Cleansing, and EDA Cleaning and EDA are important for this challenge as this data set contains many ordinal / categorical features that may be important in categorization and will need to be converted to numerical values. As a baseline, I imported the following libraries to clean, explore and model … Read moreClosing the Sale: Predicting Home Prices via Linear Regression

Nobody UNDERSTANDS Me … But Soon, Artificial Intelligence Just Might

Our faces and voices can be analyzed for emotion. As I mentioned, biomimicry, or imitating natural design in the things we create, is critical in recreating this human tendency in AI. Our end goal is artificial empathy, which (for now, at least) describes a machine’s ability to recognize and respond to … Read moreNobody UNDERSTANDS Me … But Soon, Artificial Intelligence Just Might

An introduction to high-dimensional hyper-parameter tuning

If you ever struggled with tuning Machine Learning (ML) models, you are reading the right piece. Hyper-parameter tuning refers to the problem of finding an optimal set of parameter values for a learning algorithm. Usually, the process of choosing these values is a time-consuming task. Even for simple algorithms like … Read moreAn introduction to high-dimensional hyper-parameter tuning

Vaex: Out of Core Dataframes for Python and Fast Visualization

So… no pandas ?? There are some issues with pandas that the original author Wes McKinney outlines in his insightful blogpost: “Apache Arrow and the “10 Things I Hate About pandas”. Many of these issues will be tackled in the next version of pandas (pandas2?), building on top of Apache Arrow … Read moreVaex: Out of Core Dataframes for Python and Fast Visualization

Music Genre Classification with Python

Objective Companies nowadays use music classification, either to be able to place recommendations to their customers (such as Spotify, Soundcloud) or simply as a product (for example Shazam). Determining music genres is the first step in that direction. Machine Learning techniques have proved to be quite successful in extracting trends … Read moreMusic Genre Classification with Python
