Data Science
Data Science, and more generally Artificial Intelligence (AI), differs from traditional programming and analysis in its ability to extract knowledge from data and modify its behavior and learn without specific programming. While traditional software predefines the logic that governs their processes, Data Science's algorithms build and discover models and are able to continually improve them.
Data Science brings together a set of skills including Machine Learning, Natural Language Processing (NLP), speech, images and faces recognition (among other applications). In some applications, the algorithms go so far as to simulate human intelligence.
Key Takeaways
- Data Scientists build, train, and validate models to drive critical business decisions.
- Data Scientists are concerned with data access, reproducibility, and collaboration in order to make models quickly at scale.
- Adaltas enable Data Scientists to easily build, scale, and deploy machine learning models in minutes, helping drive innovation across the business.
