Both cache() and persist() store an RDD/DataFrame/Dataset in memory (or disk) to avoid recomputation. cache() is shorthand for persist(StorageLevel.MEMORY_ONLY), while persist() offers more control.

Mainframe manufacturers defined their own proprietary network protocol stacks, e.g., IBM System Network Architecture, Digital's DECNet. These generally ran over leased lines between datacenters.

Spark offers three main APIs—RDD, DataFrame, and Dataset—each with unique advantages: RDD provides low-level control, DataFrames optimize performance, and Datasets bring type safety.

Ending the DHS would be catastrophic," says Peter Macharia, a spatial epidemiologist from Kenya, now at the Institute of Tropical Medicine in Antwerp, Belgium. Macharia says his PhD on child health interventions was based entirely on DHS data from Kenya. "Where would we get our new statistics from? We would not know what is happening in terms of health in the communities and the needs in each area," he says.

In today's hyper-digital workplace, the shift from traditional training methods to real-time insights through no-code analytics dashboards is revolutionizing Learning and Development.

The dataset for our analysis was shaped by filtering out potentially biased comments, ensuring that the final set was representative and valid for our study.

The conditional probability P(Admit∣ Female, Dept) is higher than P(Admit∣ Male, Dept) in Department A, but that advantage gets wiped out when we aggregate everything.

"Open data access is key to unlocking AI's full potential - but achieving that will require wider adoption of synthetic data tools."

Fragapane transforms cold data into engaging, emotional forms, using beauty to connect viewers with living narratives behind stark statistics.

With NannyML, we are accelerating our ability to deliver intelligent data quality infrastructure that adapts to the way modern data systems work.

To enhance construct validity, we implemented strategies such as pilot experiments for data labelling agreements and consensus involvement to mitigate personal bias.
