The tort of misappropriation occurs when one party uses another party’s work product (usually information) for commercial purposes. It involves the victim party incurring costs to gather time-sensitive information, which is then free-ridden upon by a second party in direct competition. This undermines the incentive to acquire the information originally.
Hyperparameter tuning is crucial as it directly impacts model performance. By adjusting hyperparameters, data scientists can optimize model results. Choosing appropriate values during tuning is essential for achieving accurate and high-performing models.
Transfer learning is using knowledge from one task to help with another. Fine-tuning is adjusting a pretrained model for a specific task. RAG is an NLP model that combines a language model with a knowledge retrieval system.
Fine-tuning and transfer learning involve adapting preexisting models to new tasks, while RAG is a model architecture that combines external information retrieval with generative AI abilities.
It is crucial to address flaws in pretrained models before fine-tuning because any biases or security vulnerabilities in the pretrained model can transfer to the fine-tuned model. Failure to correct these flaws beforehand can result in the persistence or worsening of these issues in the fine-tuned model.
Flaws in pretrained models can impact fine-tuned models due to heavy reliance during fine-tuning. Biases or vulnerabilities in the pretrained model may persist in the fine-tuned model, possibly worsening if not corrected beforehand.
Balancing new and previously learned knowledge during model training is crucial. Freezing too many layers can hinder adaptation to new tasks, while freezing too few may lead to loss of important pre-learned features. It’s essential to find a balance to avoid forgetting general knowledge or being unable to adapt effectively.
Overfitting in machine learning occurs when a model performs well on training data but poorly on new data due to learning irrelevant features. To mitigate it, techniques like data augmentation, regularization, and dropout layers can be used to prevent the model from memorizing noise in the data.
Fine-tuning is the process of further training a pretrained machine learning model on a smaller, specific dataset to adapt it for specialized use cases. It allows developers to enhance model performance for specific tasks efficiently, surpassing the capabilities of the original pretrained model.
Setting a lower learning rate during fine-tuning prevents drastic changes to already learned weights, preserving the model’s existing knowledge. This helps balance retaining the model’s foundational knowledge while improving its performance on the new use case by making subtle adjustments.
Fine-tuning in machine learning involves taking a pretrained model that has already learned a wide range of features and patterns from a large data set, and adapting it for specific tasks. It helps in leveraging the foundational learning of pretrained models, striking a balance between general knowledge and task-specific expertise.

It consists of layers of self-attention and fully connected neural networks, allowing it to learn complex patterns. Transformers are influential in NLP and other deep learning areas, with deep layers enabling abstraction in data, parallel processing, and training on large datasets.
Iterative querying in reducing LLM hallucinations involves an AI agent mediating calls between an LLM and a vector database multiple times to arrive at the best answer. Tools like LangChain automate management tasks and interactions with LLMs, supporting memory, vector-based similarity search, and advanced prompting techniques like chain-of-thought and FLARE. CassIO, a Python library, integrates Cassandra with generative AI by abstracting the process of accessing the database and offering ready-to-use tools.
RAG uses a knowledge base (vector database) to retrieve relevant documents based on a query’s semantic vector. A Language Model (LLM) then generates a response by summarizing the retrieved documents and the query. RAG can access external data for more accurate responses. Some RAG models incorporate fact-checking by comparing the generated response with data in the vector database.
How do tokens, vectors, and embeddings contribute to the functionality of Language Models?
Embeddings in natural language processing are vector representations of text that capture the semantic context, meaning, and relationships between words and phrases. They are generated by models like LLMs based on vast text data to enable tasks such as sentiment analysis, question answering, and text summarization with nuanced comprehension and generation capabilities.
Vectors are crucial in LLMs and generative AI for representing text or data numerically. They capture semantic meaning as embeddings, enabling natural language processing tasks. Vectors, one-dimensional arrays, are the format machines understand, and operations like dot product help identify similarities in stored vectors.

Deep learning is a form of artificial intelligence inspired by the human brain, where computers process data to recognize complex patterns. It is used for tasks like image recognition, speech transcription, and more.
CCoT is a prompt-engineering technique aimed at reducing LLM response verbosity & inference time. It reduces response length by 48.70% for multiple-choice Q&A, with unchanged problem-solving performance. For math problems, it incurs a 27.69% performance penalty, but leads to an average token cost reduction of 22.67%.
LLMs are used for generating plausible text responses, summarization, question answering, text classification, solving math problems, writing code, mimicking human speech patterns, combining information with different styles and tones. They are also used to build sentiment detectors, toxicity classifiers, and generate image captions.
Self-attention is a key concept in transformers where each token focuses on its relationship with other tokens. It asks ‘How much does every other token of input matter to me?’ For example, in a sentence, each word calculates the relevance of other words to understand pronouns or ambiguous references.
Transformers are an architecture designed around the idea of attention and are used for processing longer sequences in language modeling. They consist of an encoder and a decoder, where the encoder converts input text into an intermediate representation and the decoder converts that representation into useful text.
Large language models are trained using a large corpus of high-quality data. During training, the model iteratively adjusts parameter values through self-learning techniques, maximizing the likelihood of the next tokens in the training examples. Once trained, they can be adapted to perform multiple tasks using fine-tuning, zero-shot learning, and few-shot learning.
Large language models use multi-dimensional vectors, known as word embeddings, to represent words so that words with similar contextual meanings or other relationships are close in the vector space. Transformers then pre-process text using word embeddings to understand word and phrase context, parts of speech, and other relationships, before producing unique outputs through the decoder.

Ensuring diverse, representative, and fair data is essential for building equitable AI systems because biases in training data can lead to biased AI decisions, posing ethical concerns. AI systems are only as good as the data they are trained on, so if the data is biased, the AI will also be biased. Therefore, diverse and representative data is necessary to train AI systems that make fair and unbiased decisions.
