Basics of Developing Natural Language Processing (NLP) Solutions with Azure AI Services

Entertainment

Introduction

Introduction

Welcome to the fifth session of our Azure AI Engineer Associate Boot Camp! Today, we delve into the basics of developing Natural Language Processing (NLP) solutions using Azure AI Services. NLP plays a critical role in artificial intelligence, enabling machines to understand, interpret, and respond to human language. By the end of this session, participants will have a solid foundation for utilizing Azure's NLP capabilities in their projects.

What is AI?

Artificial Intelligence (AI) embodies various technologies that perform tasks associated with human-like capabilities. These include visual perception, speech recognition, decision making, and language processing. We encounter AI in our daily lives, from digital assistants like Siri and Google Assistant to smart technologies in connected vehicles.

Key Components of AI:

  1. Visual Perception: Recognizing and interpreting images, videos, and live camera input.
  2. Text Analysis: Understanding and extracting meaningful insights from text.
  3. Speech Service: Transforming spoken language into recognized text and vice versa.
  4. Decision Making: Using historical data to inform actions and predictions.

The Interrelation of Data Science, Machine Learning, and AI

Data Science, Machine Learning (ML), and AI are closely intertwined fields. Data science involves data processing and analysis to uncover patterns, while Machine Learning focuses on training predictive models. Finally, AI replicates human intelligence characteristics to solve complex problems.

Introduction to Generative AI

Generative AI refers to technologies capable of creating new content, such as text, images, audio, and videos. Many of us utilize generative AI applications like ChatGPT and Copilot, where AI recognizes patterns to produce novel content. Microsoft Azure offers tools like Azure OpenAI Studio to create and customize generative AI models based on specific datasets.

Building Responsible AI Solutions

When developing AI applications, it's crucial to consider ethical aspects, including fairness, reliability, privacy, inclusiveness, transparency, and accountability. A responsible AI system should treat all users equitably, ensure reliable performance, and prioritize user data protection.

Key Attributes of Responsible AI:

  1. Fairness: Ensuring unbiased outcomes regardless of user characteristics.
  2. Reliability and Safety: AI systems must perform consistently to avoid harmful consequences.
  3. Privacy and Security: Safeguarding user data and respecting privacy regulations.
  4. Inclusiveness: Empowering users from all backgrounds.
  5. Transparency: Users must understand how AI systems operate and their limitations.
  6. Accountability: Clear responsibility in case of failures or errors.

Azure AI Services for NLP
