• What is the Practical Data Science Specialization about?

  Development environments might not have the exact requirements as production environments. Moving data science and machine learning projects from idea to production requires state-of-the-art skills. You need to architect and implement your projects for scale and operational efficiency. Data science is an interdisciplinary field that combines domain knowledge with mathematics, statistics, data visualization, and programming skills. The Practical Data Science Specialization brings together these disciplines using purpose-built ML tools in the AWS cloud. It helps you develop the practical skills to effectively deploy your data science projects and overcome challenges at each step of the ML workflow using Amazon SageMaker. This Specialization is designed for data-focused developers, scientists, and analysts familiar with the Python and SQL programming languages and want to learn how to build, train, and deploy scalable, end-to-end ML pipelines - both automated and human-in-the-loop - in the AWS cloud. Each of the 10 weeks features a comprehensive lab developed specifically for this Specialization that provides hands-on experience with state-of-the-art algorithms for natural language processing (NLP) and natural language understanding (NLU), including BERT and FastText using Amazon SageMaker. In this Specialization, you will master how to remove obstacles to advance your projects from idea to deployment quickly and to scale to thousands of models or more. Learn how to prepare massive datasets originating from social media channels, mobile/web applications, or other public/private data sources that don’t fit in your local hardware and use them for training models. Understand how to tune models for the highest accuracy and then deploy and manage them over time.

• What are the benefits of running data science projects in the cloud?

  One of the biggest benefits of developing data science projects in the cloud is the agility to scale up and out at a minimum cost. The cloud brings together data, low-cost storage, security, and ML services along with high-performance CPUs and GPUs for model training and deployment. As a result, you can store as much data as you need and use high-performance compute elastically, so it’s much faster to realize the value of machine learning. This Specialization provides tools to analyze and clean the data, extract relevant features, and teach you how to use tools purpose-built for ML such as visual development environment, debuggers, profilers, and pipelines to scale models building, training, and deployment.

• What will I learn in the Practical Data Science Specialization?

  1. Prepare data, detect statistical data biases, and perform feature engineering at scale to train models
  2. Automatically train, evaluate, and tune models with automated machine learning (AutoML)
  3. Store and manage machine learning features using a feature store
  4. Debug, profile, tune and evaluate models while tracking data lineage and model artifacts
  5. Build, deploy, monitor, and operationalize end-to-end machine learning pipelines.
  6. Build data labeling and human-in-the-loop pipelines to improve model performance with human intelligence

• What will I be able to do upon completing the Practical Data Science Specialization?

  By the end of this Specialization, you will be ready to:

  • Ingest, register, and explore datasets
  • Detect statistical bias in a dataset
  • Automatically train and select models with AutoML
  • Create machine learning features from raw data
  • Save and manage features in a feature store
  • Train and evaluate models using built-in algorithms and custom BERT models
  • Debug, profile, and compare models to improve performance
  • Build and run a complete ML pipeline end-to-end
  • Optimize model performance using hyperparameter tuning
  • Deploy and monitor models
  • Perform data labeling at scale
  • Build a human-in-the-loop pipeline to improve model performance
  • Reduce cost and improve performance of data products

• What background knowledge is necessary for the Practical Data Science Specialization?

  Learners should have a working knowledge of ML algorithms and principles, be proficient in Python programming at an intermediate level, and be familiar with Jupyter notebooks and statistics. We recommend you complete the Deep Learning Specialization or an equivalent program. 

  Learners should also be familiar with the fundamentals of AWS and cloud computing. Completion of Coursera AWS Cloud Technical Essentials or similar is considered the prerequisite knowledge base.

• Who is the Practical Data Science Specialization for?
