gradient boosting classifier

June 24, 2025 Pere No comments yet

Boosting in machine learning is a technique that combines multiple simple models, often decision trees into a single, stronger model. It works with regression trees and improves performance by sequentially learning from the mistakes of previous models. According to the scikit-learn documentation, at each stage, a regression tree is fit on the negative gradient of […]

Random Forest Regressor

June 24, 2025 Ryan Nolan No comments yet

Random forest regressor is a variant of the random forest classifier. It is primarily used for classification tasks. This model is an ensemble of decision trees. It combines the predictions of multiple individual trees to imrpove performance. By aggregating the results from those trees, typically through votng or avaeraging. It produces a final prediction that […]

Python sets

June 21, 2025 Ryan Nolan No comments yet

A set in Python is a built-in data type used to store unique elements—that is, it automatically removes duplicates. Sets are defined using curly braces {}, and they are unordered and unindexed, meaning the items have no specific position or order. While sets are generally unchangeable in terms of individual items (you can’t change elements […]

N8N Google Sheets

June 21, 2025 Ryan Nolan No comments yet

Integrating in Google Sheets in an N8N workflow is pretty common. In fact when taking a look at jobs on freelance websites like Upwork I often see requests that have Google Sheets as part of a build a customer wants There are quite a few usecases in which this can be used. Two common ones are: Extracting data […]

Python If Elif Else

June 20, 2025 Ryan Nolan No comments yet

Conditional Statements and Logical Operators in Python Use if, elif, and else to control the flow of your program based on conditions. You can write nested conditions (conditions inside other conditions) for more complex logic. Python supports comparison operators (like ==, !=, <, >, <=, >=) to compare values. You can combine conditions using logical […]

Python Variables

June 20, 2025 Ryan Nolan No comments yet

Variables are used to store data in a computer’s memory. A variable’s name should clearly describe the kind of data it holds. In Python, you don’t need to declare the data type of a variable—Python automatically detects it. Some common data types in Python include: Integers (int) for whole numbers Floats for decimal numbers Booleans […]
