Generate synthetic data at scale! SDV is an open-source Python library that generates tabular synthetic data by using ML algorithms to learn and replicate patterns from your real data. Here's how it works in 3 steps: 1๏ธโƒฃ Train: Point SDV at your real table; it will capture the underlying distributions & relationships. 2๏ธโƒฃ Generate: Run the trained SDV model to pop out as many look-alike rows as you needโ€”no real data exposed. 3๏ธโƒฃ Validate: Use SDVโ€™s quality report to see how closely the generated data matches the real stuff; tweak and repeat if you want it tighter. Class imbalanceโ€”solved in one shot! โœจ Key features: ๐Ÿง  Multiple models from GaussianCopula to CTGAN ๐Ÿ”— Single, multi & sequential-table support ๐Ÿ”’ Built-in anonymization & logical constraints โš™๏ธ Single call does it all `sdv.sample()` Link to the GitHub repo in next tweet! ____ Share this with your network if you found this insightful โ™ป๏ธ Follow me ( @akshay_pachaar ) for more insights and tutorials on AI and Machine Learning!

Today, we are excited to introduce a very powerful new framework to The Synthetic Data Vault : ๐—ฐ๐—ผ๐—ป๐˜€๐˜๐—ฟ๐—ฎ๐—ถ๐—ป๐˜ ๐—ฎ๐˜‚๐—ด๐—บ๐—ฒ๐—ป๐˜๐—ฒ๐—ฑ ๐—ด๐—ฒ๐—ป๐—ฒ๐—ฟ๐—ฎ๐˜๐—ถ๐—ผ๐—ป (#CAG for short). CAG addresses the shortcomings of generative models in capturing the context buried in enterprise data stores - with human input. (Link to the announcement: datacebo.com/announcements/iโ€ฆ) โŽ ๐—š๐—ฒ๐—ป๐—ฒ๐—ฟ๐—ฎ๐˜๐—ถ๐˜ƒ๐—ฒ ๐—”๐—œ ๐—บ๐—ผ๐—ฑ๐—ฒ๐—น๐˜€ ๐—ณ๐—ฎ๐—ถ๐—น ๐˜๐—ผ ๐—ฐ๐—ฎ๐—ฝ๐˜๐˜‚๐—ฟ๐—ฒ ๐—ฑ๐—ฒ๐˜๐—ฒ๐—ฟ๐—บ๐—ถ๐—ป๐—ถ๐˜€๐˜๐—ถ๐—ฐ ๐—ฟ๐—ฒ๐—น๐—ฎ๐˜๐—ถ๐—ผ๐—ป๐˜€๐—ต๐—ถ๐—ฝ๐˜€ ๐—ฏ๐—ฒ๐˜๐˜„๐—ฒ๐—ฒ๐—ป ๐—ฐ๐—ผ๐—น๐˜‚๐—บ๐—ป๐˜€, ๐—ฟ๐—ผ๐˜„๐˜€, ๐—ฎ๐—ป๐—ฑ ๐˜๐—ฎ๐—ฏ๐—น๐—ฒ๐˜€. We call such relationships database context. Database context describes hard and fast rules under which data is created and stored. What is even harder is that usually, this context is not explicitly stored within the database schema itself โ€“ but data teams know that it exists. Downstream applications process this data based on the context using logic within the application software. When the generative models are used to create #syntheticdata the expectation is that the #syntheticdata will also follow the database context. โœ… When we launched The Synthetic Data Vault โ€” a system to enable enterprises to build generative models for their own #multitable data โ€” we provided the ability to include context via what we called #๐—ฐ๐—ผ๐—ป๐˜€๐˜๐—ฟ๐—ฎ๐—ถ๐—ป๐˜๐˜€. ๐Ÿ”ฅ Over the years, ๐—ฐ๐—ผ๐—ป๐˜€๐˜๐—ฟ๐—ฎ๐—ถ๐—ป๐˜๐˜€ ๐—ต๐—ฎ๐˜€ ๐—ฏ๐—ฒ๐—ฐ๐—ผ๐—บ๐—ฒ ๐—ผ๐—ป๐—ฒ ๐—ผ๐—ณ ๐˜๐—ต๐—ฒ ๐—บ๐—ผ๐˜€๐˜ ๐—ฝ๐—ผ๐—ฝ๐˜‚๐—น๐—ฎ๐—ฟ ๐—ณ๐—ฒ๐—ฎ๐˜๐˜‚๐—ฟ๐—ฒ๐˜€ ๐—ผ๐—ณ ๐—ผ๐˜‚๐—ฟ ๐—ฆ๐——๐—ฉ ๐—˜๐—ป๐˜๐—ฒ๐—ฟ๐—ฝ๐—ฟ๐—ถ๐˜€๐—ฒ ๐—ฝ๐—ฟ๐—ผ๐—ฑ๐˜‚๐—ฐ๐˜. ๐Ÿ’ช ๐—ช๐—ถ๐˜๐—ต ๐—–๐—”๐—š ๐˜„๐—ฒ ๐—ฎ๐—ฟ๐—ฒ ๐—ฑ๐—ผ๐˜‚๐—ฏ๐—น๐—ถ๐—ป๐—ด ๐—ฑ๐—ผ๐˜„๐—ป ๐—ผ๐—ป ๐˜๐—ต๐—ถ๐˜€ ๐—ณ๐—ผ๐—ฐ๐˜‚๐˜€. To use this new and powerful framework, users can just pick the pre-defined pattern that corresponds to their database context and tell SDV where to apply it.

Working with customers all over the world has taught us about one important, but often overlooked benefit of using #syntheticdata: increased data diversity. Data diversity refers to the overall variety of data that is accessible for a project. While it's a simple concept, increasing data diversity can deliver enormous value to an organization โ€” allowing for more robust testing, better predictions, and even higher creativity. In our latest blog post, (link: lnkd.in/eumZtB38) Neha Patki elaborates this concept using some concrete examples. In the blog we cover: โœณ๏ธ How #generativeai models in #SDV (@sdv_dev ) can create #syntheticdata that is diverseย ? โœ… How generative models maintain the delicate balance between creating novel (diverse) data and preserving high degree of statistical resemblance to real data โŽ While we can create really diverse data using random data generators, they wonโ€™t resemble the real data. Also in this blog are examples of how data diversity as generated by #syntheticdata impacts the outcomes.ย (Links to each of these case studies are in the blog as well) Diverse synthetic data enables creation of a more robust product. ING creates synthetic financial transactions with 100x the combinations present in their real data. This allows them to thoroughly test all aspects of a complicated payments service, and keep their payments systems working. Diverse #syntheticdata can help make better predictions. A research team at UCLA (@UCLA ) created synthetic credit card fraud events, which combined different characteristics of real fraud events into rarer occurrences. The synthetic data allowed them to better predict future credit card fraud by nearly 20x. It allows product development teams to navigate new ideas. One promising new direction for research and development teams involves using synthetic data to invent brand new products by combining attributes of existing ones.
