Prompt Injection is a security vulnerability in AI systems, particularly large language models (LLMs). It occurs when an attacker manipulates model behavior by inserting malicious instructions into user input. As a result, the model may bypass intended restrictions, leak information,...

Prompt Engineering is the process of crafting effective inputs to guide the behavior of large language models (LLMs) and other AI systems. By carefully designing prompts, users can influence the quality, relevance, style, and accuracy of AI-generated outputs. Prompt engineering...

Pre-training is the process of training a machine learning model on a large, general-purpose dataset before adapting it to a specific task. By learning broad patterns, structures, and representations from unlabeled or widely available data, a model develops a rich...

Post-training refers to the stage that follows the initial model training process, focusing on refining, optimizing, and preparing the model for deployment in real-world scenarios. After a model has been trained—often through pre-training and fine-tuning—it may still benefit from additional...

In the context of natural language processing (NLP) and machine learning, perplexity is a metric used to evaluate the performance of language models. It measures how well a model predicts a sequence of words, with lower perplexity indicating better performance....

Parameter refers to the internal variables of a machine learning model that are learned from training data. These values define how input features are transformed into outputs, and they are crucial for determining the model’s behavior and accuracy. Parameters are...

Open Source refers to software or projects where the source code is made publicly available, allowing anyone to view, modify, and distribute it. Open-source development promotes collaboration, transparency, and community-driven innovation. Many foundational technologies in AI, cloud computing, and web...

Node refers to a fundamental unit used across various fields of computing and networking. In computer science, it typically represents a single point within a data structure, network, or system. Depending on the context, a node can serve as a...

Natural Language Processing (NLP) is a field of artificial intelligence that focuses on enabling computers to understand, interpret, and generate human language. It combines linguistics, machine learning, and computational techniques to process and analyze natural language data, such as text...

A neural network is a computational model inspired by the human brain, designed to recognize patterns and relationships within data. It consists of interconnected layers of nodes (or neurons) that process and transmit information to solve tasks like classification, prediction,...
