I was at a meeting last week discussing how AI models might be used to support archives forefficiency, effectiveness, etc. while maintaining the requirements for those archives to providereliable and authentic records and maintain confidentiality of relevant record data elements. Someone across the room indicated that they were going to federate models, not records themselves, …
Creating an optimal model that strikes a balance between underfitting and overfitting requires careful consideration. To assess how well our model performs on new, unseen data, we employ the train-test split technique and cross-validation. Train-Test Split: To evaluate a model’s performance, we split the dataset into a training set (approximately 70-90% of the data) and …

The Pearson correlation coefficient (denoted as “r”) is widely used in statistics to measure the strength and direction of linear relationships between variables, ranging from -1 (perfect negative linear correlation) to +1 (perfect positive linear correlation). A Pearson correlation coefficient of 0 typically implies the absence of a linear relationship between variables. However, the term …
Standard deviation and standard error are two statistical measures that often get confused with each other. While both measures describe the variability in the data, they serve different purposes. Standard deviation measures the spread of the data. It calculates how far the individual data points deviate from the mean of the data set. A low …

A new tactic appears to have arisen in the use of generative AI in social media. This tactic is comprised of rapidly generating seemingly knowledgeable responses to other people. One of the many challenges of this approach is that the generative AI is so lightweight in terms of understanding (It has none), that it mistakes …
