Recognize ChatGPT's strengths in generating contextual text and processing large data, and its limitations like biases and the risk of misleading or incorrect information, grounded in the transformer architecture.

Explore the fundamentals of natural language processing and how NLP enables computers to understand, interpret, and generate human language, powering text analysis and natural human-computer interactions.

Explore how natural language processing enables applications like sentiment analysis, translation, and text summarization for businesses and researchers. Learn tokenization as a fundamental pre-processing step that breaks text into tokens.

Compare stemming and lemmatization, where stemming trims affixes to root forms and lemmatization uses context to yield base forms, with examples like running, run, and runner.

Learn how part of speech tagging assigns categories to tokens, tagging nouns, verbs, adjectives, and adverbs to reveal sentence structure and support nlp tasks like parsing and named entity recognition.

Explore dependency parsing to map grammatical relationships into a dependency tree that clarifies sentence meaning. Learn named entity recognition (NER) to identify people, locations, and dates for information extraction.

Develop coreference resolution to identify when different words refer to the same entity, enabling coherent summaries and translations. This technique supports summarization, question answering, and text analysis by clarifying entities.

Explore sentiment analysis, also known as opinion mining, to identify emotion in text and classify as positive, negative, or neutral, with applications in social media monitoring and market research.

Explore machine translation using NLP techniques to enable seamless cross-language communication. Master text summarization to generate concise, information-rich summaries of lengthy texts.

Learn how language modeling builds statistical models to predict likelihood of word or character sequences, enabling next-word predictions that power translation, speech recognition, and text generation, including ChatGPT and Bert.

Explore how rule-based and statistical nlp address ambiguity, idiomatic expressions, and language variations to build robust language understanding.

Deep learning reshapes NLP with RNNs and transformers, improving machine translation and sentiment analysis. The lecture demonstrates a feedforward neural network using tokenization, word embeddings, and labeled training data.

ChatGPT uses NLP techniques and transformers to understand and generate coherent, engaging responses in conversational settings, illustrating the fundamentals that enable and limit intelligent language systems.

Explore retrieval augmented generation (rag) to keep AI up to date by retrieving new information before answering, reducing errors and outperforming traditional llms like ChatGPT by avoiding hallucinations.

Explore retrieval augmented generation (rag) and combination of retrieval from external sources with generation via a large language model to enhance accuracy, reduce hallucinations, and enable knowledge for prompt engineers.

Explore rag-powered AI that retrieves live research papers and news articles to verify facts and stay up to date, boosting accuracy and reliability beyond standard LLMs.

Unpack how RAG works: convert queries to vectors, retrieve data from vector databases like Astra DB or Pinecone, and generate accurate, up-to-date responses with an LLM.

Load high quality data into a rag system, chunk text, create embeddings, and store them in a vector database to enable meaningful contextual matches and llm responses via the retriever.

Explore LangChain and LangFlow to build efficient retrieval-augmented generation pipelines, leveraging document loaders, retrievers, and memory to fetch relevant data from vector databases and generate informed responses.

Rag delivers accurate, up-to-date responses by retrieving external data, reducing hallucinations, and enabling domain-specific customization. However, it adds complexity, slower searches, and data security concerns, best for accuracy-critical use.

Install and run LangFlow and LM Studio to set up a RAG environment. Learn to install Python, add to path, pip install LangFlow, and explore the GUI and RAG features.
