Neural Network: A network of nodes (or artificial neurons) that process data in layers, emulating the human brain’s structure
Overfitting: Sometimes, a model becomes too good at memorizing the training data, including its noise and inconsistencies. When faced with new, slightly different prompts, it might rely on these memorized patterns rather than generating truly novel and accurate information. It is like a student who memorizes answers for a specific test but doesn't understand the underlying concepts.
Parameters: Values within a model that are optimized during training to best fit the data
Pre-training: The initial phase in training a model where it learns from a broad data set without specific targets to develop a general understanding
Prompt Chaining: This technique involves linking multiple prompts together in a sequence, with each new prompt building on the output from the previous one. This method is useful for solving multi-step tasks or generating refined outputs over time. ○ Example: In a multi-step task like writing a marketing headline, the AI would first determine the target audience, then identify the most resonant message, and finally generate a headline based on these insights.
Prompt
Engineering: The way a user phrases a question or provides instructions can
inadvertently lead an AI to hallucinate. Ambiguous prompts or those that imply
a certain answer might steer the model toward generating a plausible sounding
but incorrect response.
Quantum computing uses quantum mechanics to process information, deploying hardware and algorithms to solve complex problems surpassing the speed of supercomputers. It uses qubits instead of binary (0 or 1) to execute multidimensional quantum algorithms. Quantum computing has vast potential independently, however, its conjunction with AI yields transformative outcomes. Ongoing efforts are directed towards seamless integration of AI with quantum computing, resulting in more potent AI models along with noteworthy advancements in speed, efficiency, and accuracy of AI.

Example: The AI may explore different approaches to crafting a marketing message for an eco-friendly product, focusing on various aspects like affordability, sustainability, or innovation.
Underfitting: This happens when a model cannot learn the underlying patterns in the training data, resulting in poor performance on both training and test datasets. It is typically caused by high bias, where the model makes overly simplistic assumptions about the data. Examples include using a linear model for a non-linear relationship or a shallow decision tree for complex data. Symptoms of underfitting include consistently high errors across training and validation sets. Common causes are insufficient model complexity, inadequate features, or poor data quality.

Useful when labeling data is impractical, or the nature of the problem does not permit predefined outputs. Example: customer segmentation models group profiles based on detected patterns without prior output labels
