Convert array to list in Java [4 methods]

In Java, arrays and lists are two fundamental data structures. Arrays have a fixed length and are used to store a collection of elements of the same type. Lists, on the other hand, are dynamic and can grow or shrink as needed to store a collection of elements. In Java, it is often necessary to convert an array to a list or vice versa. In this article, we will explore several ways to convert an array to a list in Java.

Biomedical Image Segmentation

Introduction

Image segmentation is the process of partitioning a certain image into several regions of interest (ROI). In the Biomedical field segmented images can be used for anomaly detection, diagnosing diseases, computer-integrated surgery, treatment planning, studying anatomical structures, and much more. One of the advantages of having automated image segmentation methods is it’s not expensive and requires less work compared to manual segmentation. Automated image segmentation, when built ...

Multi-Layer Perceptron (MLP): A Basic Understanding

Introduction

Multi Layer Perceptron (MLP) is a type of artificial neural network that is widely used for various machine learning tasks such as classification and regression. It is called a multi-layered perceptron because it has many layers of nodes (known as artificial neurons) that connect to each other. In this article, we will explore the main features and components of MLP, its architectural and training processes, and its programs in various fields.

History

MLP was first introduced in the...
