Java Local Inner Classes

In this article at OpenGenus, we will discuss what local inner classes are in Java, some properties of local inner classes in relation to standard inner classes/Java classes declared in a standalone files, and some use cases for local inner classes.

What are Local Inner Classes?

Syntactically, local inner classes, in Java are simply classes declared within the body of any code block, such as within a method body or within a loop. Furthermore, they are declared in the same way that you would decl...

Concept of Multiple Instance Learning (MIL)

In the field of machine learning, Multiple Instance Learning (MIL) is a paradigm that expands upon traditional supervised learning. MIL differs from conventional supervised learning, where each training instance is individually labeled. Instead, MIL operates on sets of instances called bags, with each bag associated with a single label. The objective is to develop a model that can effectively classify unseen bags based on their content. MIL has attracted considerable attention due to its capacit...

Introduction Stack::Empty Complexity Real-World Applications Practice Questions

Reading time: 5-10 minutes | Coding time: 2 minutes

Introduction

In C++, a stack is a data structure that stores elements following Last-In-First-Out (LIFO) ordering. Before using stack::empty, you must first initialize a stack in your code. To allow their usage, the C++ standard library provides the stack class, which provides a list of functions and operations for working with stacks. In or...

Megatron NLG model

Introduction

NVIDIA created the massive transformer-based NLG model known as Megatron. It is based on the transformer architecture and made to produce text that resembles human speech quickly and accurately. It is intended to produce excellent text that, in terms of grammar, style, and coherence, resembles human-written text.

Using distributed training methods, the initial Megatron model was trained on enormous amounts of text data and released in 2019. It could produce excellent text in a range...
