Study Notes

Natural Language Processing Basics

NLP is a field of AI combining computer science and linguistics for computers to understand, interpret, and generate human language.
NLP tasks include sentence meaning, text detail recognition, language translation, answering questions, text summarization, and human-like responses.
NLP is prevalent in daily life, e.g., email suggestions, virtual assistants, customer service chatbots, and translation apps.

A Very Brief History of NLP

NLP's roots trace back to the 1950s with researchers attempting computer understanding and generation of human language.
The Turing Test measures a machine's ability to answer questions indistinguishably from a human.
Early machine translation systems were sentence and phrase-based, with limitations due to reliance on specific language patterns.
The 1960s saw rule-based systems enabling computers to perform tasks and have conversations.
The 1970s and 80s delved into knowledge-based approaches using linguistic rules, reasoning, and domain knowledge.
Statistical approaches became popular in the 1990s and early 2000s alongside advancements in speech recognition, machine translation, and algorithms.
The introduction of the World Wide Web in 1993 provided text data for NLP research.
Neural networks and deep learning dominated NLP research after 2009.

Human Language Is "Natural" Language

Natural language refers to how humans communicate using words and sentences in conversations, reading, and writing.
Natural language is unstructured data; while humans understand the meanings, computers need structuring for proper comprehension from data.
Artificial Intelligence Fundamentals covered unstructured and structured data.

Natural Language Understanding and Natural Language Generation

Natural Language Understanding (NLU) processes unstructured data to structured data.
NLU techniques interpret written or spoken language to derive meaning and context.
Natural Language Generation (NLG) generates human-like language from structured data.
NLG enables computers to create human language.

Basic Elements of Natural Language Parsing

Natural language parsing is a fundamental challenge, dealing with complexity, nuances, ambiguity, and common mistakes in human language (e.g., different meanings for similar-sounding words, misspellings).
The process involves segmenting text into chunks, tokenizing to split sentences into words, stemming to derive word roots, or lemmatization considering part-of-speech.

Parsing Natural Language

Natural language parsing is akin to teaching a child reading; it involves recognizing word meanings, sounds, and relationships.
Computers use algorithms, large language models (LLMs), statistical models, and machine learning algorithms for text processing.
Syntactic parsing analyzes language structure, while semantic parsing attempts to understand meaning.

Data Fundamentals for AI

Data is a vital asset for gaining insight into operations and customers. It's used in numerous forms and for numerous reasons.
Data-driven decision-making is a significant process using data analysis instead of intuition. It requires accurate and reliable data.
Data quality includes ensuring accuracy, completeness, and avoiding subjectivity. Data cleaning is often needed for effective data application.

Data Classification and Types

Data is categorized into structured, unstructured, and semi-structured forms.
Structured data (e.g. tables, spreadsheets, databases) is formatted in a specific way, whereas unstructured data (e.g. text documents, images, videos, social media posts) has no pre-defined format.
Semi-structured data contains some structure but isn’t completely formatted, like XML or JSON files.

Data Collection Methods

Data collection involves gathering information from various sources: internal (e.g., sales data), external (e.g., market research), and public datasets.
Data is collected in different formats, such as tabular data, text data, image data, and geospatial data.
Data labeling and cleaning are vital steps in improving quality for any AI processes.

The Role of Machine Learning

Machine learning is a part of AI where computers learn from data without explicit programming, allowing them to create their own rules or models.
Machine learning differs from traditional programming as computer systems create and apply rules based on algorithms and on input from data, rather than receiving explicit instructions from programmers.
Data quality is a key driver of successful machine learning as it affects the accuracy of models, influencing what patterns and relationships the software identifies.

Predictive Vs Generative AI

Predictive AI makes predictions based on labeled data, like fraud detection.
Generative AI creates new content, such as images, music, or text, and is valuable in creative fields.
Both are crucial but different types of AI tools impacting various applications.

Data Lifecycle for AI

The data lifecycle involves data collection, storage, processing, analysis, and eventual deletion.
Ethical considerations guide data management processes. Different stages in the lifecycle require diverse techniques, tools, and procedures for best results.

Know Data Ethics, Privacy, and Practical Implementation

Data ethics highlights ethical concerns around data collection, analysis, and usage within AI applications.
Ethical considerations include privacy violations, data breaches, and biased decision-making.
Effective data lifecycle management best practices can enhance data handling and data quality.

Legal and Regulatory Frameworks for Data and AI

Legal frameworks for data protection, like CCPA or GDPR, are critical for responsible data handling.
These regulations address data collection, use, sharing, and disposal, ensuring responsible AI application.
