Tree-based models have become a popular choice for Machine Learning, not only due to their results, and the need for fewer transformations when working with data (due to robustness to input and scale invariance), but also because there is a way to take a peek inside of them to see...

Decision trees are widely used in machine learning problems. We'll assume you are already familiar with the concept of decision trees and you've just trained your tree based algorithm! Advice: If not, you can read our in-depth guide on "Decision Trees in Python with Scikit-Learn guide". Now, it...

The Random Forest algorithm is one of the most flexible, powerful and widely-used algorithms for classification and regression, built as an ensemble of Decision Trees. If you aren't familiar with these - no worries, we'll cover all of these concepts. In this in-depth hands-on guide, we'll build an intuition on...
The Random Forest algorithm is a tree-based supervised learning algorithm that uses an ensemble of predicitions of many decision trees, either to classify a data point or determine it's approximate value. This means it can either be used for classification or regression. When applied for classification, the class of the...
Suppose you want your Keras model to have some specific behaviour during training, evaluation or prediction. For instance, you might want to save your model at every training epoch. One way of doing this is using Callbacks. In general, Callbacks are functions that are called when some event happens, and...

Object detection has been gaining steam, and improvements are being made to several approaches to solving it. In the past couple of years, YOLO-based methods have been outperforming others in terms of accuracy and speed, with recent advancements such as YOLOv7 and YOLOv6 (which was released independently, after YOLOv7). However...

Object detection is a large field in computer vision, and one of the more important applications of computer vision "in the wild". From it, keypoint detection (oftentimes used for pose estimation) was extracted. Keypoints can be various points - parts of a face, limbs of a body, etc....
Object detection is a large field in computer vision, and one of the more important applications of computer vision "in the wild". From it, instance segmentation was extracted, and is tasked with having models predict not only the label and bounding box of an object, but also the...
The learning rate is an important hyperparameter in deep learning networks - and it directly dictates the degree to which updates to weights are performed, which are estimated to minimize some given loss function. In SGD: $$ weight_{t+1} = weight_t - lr * \frac{derror}{dweight_t} $$ With a learning...
