These models handle large tabular datasets with small parameter spaces, requiring innovative data solutions. At Yelp, we encountered challenges that prompted us to enhance the training time of our ad-revenue generating models, which use a Wide and Deep Neural Network architecture for predicting ad click-through rates (pCTR).
Introduction Big Data is a large and complex dataset generated by various sources and grows exponentially. It is so extensive and diverse that traditional data processing methods cannot handle it. The volume, velocity, and variety of Big Data can make it difficult to process and analyze.
Matthaus gives the dlt vision about creating the foundation for developers to be able to create sources in a wink creating a large ecosystem of APIs datasets easily maintainable. This is Croissant. Starting today it will be supported by 3 majors platforms: Kaggle, HuggingFace and OpenML.
Tajinder’s passion for unraveling hidden patterns in complex datasets has driven impactful outcomes, transforming raw data into actionable intelligence. Introduction Meet Tajinder, a seasoned Senior Data Scientist and ML Engineer who has excelled in the rapidly evolving field of data science.
Images and Videos: Computer vision algorithms must analyze visual content and deal with noisy, blurry, or mislabeled datasets. They are responsible for designing, implementing, and maintaining robust, scalable data pipelines that transform raw unstructured data—text, images, videos, and more—into high-quality, AI-ready datasets.
Data enrichment is the process of augmenting your organizations internal data with trusted, curated third-party datasets. The Multiple Data Provider Challenge If you rely on data from multiple vendors, you’ve probably run into a major challenge: the datasets are not standardized across providers. What is data enrichment?
Big data is nothing but the vast volume of datasets measured in terabytes or petabytes or even more. Introduction In this technical era, Big Data is proven as revolutionary as it is growing unexpectedly. According to the survey reports, around 90% of the present data was generated only in the past two years.
The Medallion architecture is a framework that allows data engineers to build organized and analysis-ready datasets in a lakehouse environment. For instance, suppose a new dataset from an IoT device is meant to be ingested daily into the Bronze layer. How do you ensure data quality in every layer?
This hybrid approach empowers enterprises to efficiently handle massive datasets while maintaining flexibility and reducing operational overhead.

Synthetic data works by leveraging models to create artificial datasets that reflect what someone might find organically (in some alternate reality where more data actually exists), and then using that new data to train their own models. But is synthetic data a long-term solution? Probably not.
Different schemas, naming standards, and data definitions are frequently used by disparate repository source systems, which can lead to datasets that are incompatible or conflicting. To guarantee uniformity among datasets and enable precise integration, consistent data models and terminology must be established.
