This means developing strategies to capture, gather, and clean data from various sources. After organizing and exploring this data, they can then build solutions and communicate their findings to the wider business. Data scientists often work with other professionals, including data engineers, ...
Now, let’s look at how we can experiment with DAX and query changes in DAX Studio.Modifying and tuning queriesEarlier in this section, we saw how we could capture a query generated by a Power BI visual and then display its text. A nice trick we can use here is to use query-scoped...
Embeddings are among the key building blocks of large language models (LLMs) that ensure efficient processing of natural language data. Hence, these vector representations are crucial in making AI systems understand human language meaningfully. The vectors capture the semantic meanings of words or toke...
The factors are constructed in such a way that they capture the maximum possible information from the original variables. This technique is often used in market research, customer segmentation, and image recognition. Learn more about factor analysis in R with our course, which explores latent ...
Polynomial Features: Generating higher-degree features helps capture non-linear relationships between variables. Polynomial features often enhance model performance for datasets where linear models underperform. Domain-Specific Features: Using domain knowledge to create meaningful features tailored to the specific...

Change data capture (CDC) continuously identifies and captures incremental changes to data and data structures (aka schemas) from a source such as a production database. CDC arose two decades ago to help replication software deliver real-time transactions to data warehouses, where the data is the...
It may result from using an overly simple algorithm or inadequate model capacity to capture the intricacies of the data. Underfitting often arises when the model is not given sufficient training time or when the complexity of the problem is underestimated. To address underfitting, one can try ...
