What is NumPy? NumPy is a Python library for arrays. It also has functions for working in algebra, Fourier transforms, and matrices. Travis Oliphant created NumPy in 2005. It is an open-source project, and you can use it freely. It stands for Numerical Python. NP is a Python library written partially in Python, but most …
Now we’ll explore how Canny Edge Detection works and implement it using Python with OpenCV.Edge detection is a fundamental technique in image processing and Computer Vision, used to identify the boundaries of objects within an image. Canny Edge Detection stands out as one of the most robust and widely used techniques among the various edge …

Handling missing data is a crucial step in data preprocessing. When working with real-world datasets, missing values are common due to various reasons such as data entry errors, sensor malfunctions, or incomplete surveys. If not handled properly, missing data can lead to biased results and reduced accuracy in machine learning models. Ignoring missing data can …

Imbalanced datasets are a common challenge in machine learning. This occurs when one class has significantly fewer samples compared to the other, leading to biased models that favor the majority class. Such imbalances can result in misleading accuracy scores, as the model may predict the majority class correctly while failing to identify the minority class …
