- A simple map stage transforms items with a stateless function; a more complex windowed group-and-aggregate stage groups events by key in an infinite stream and calculates an aggregated value over a sliding window.
- When counting the records in the stream, for example, you have to maintain the current count.
- This code samples shows both stateless and stateful transformations: – – In the most general case, the state of stateful transformations is affected by all the records observed in the stream, and all the ingested records are involved in the computation.
- This fact can be leveraged for easy parallelization by partitioning the data stream on the grouping key and letting independent threads/processes/machines handle records with different keys.
- This example processes a stream of text snippets (tweets or anything else) by first splitting them into individual words and then performing a windowed group-and-aggregate operation.

- Deep learning and machine learning both offer ways to train models and classify data.
- To have a computer do classification using a standard machine learning approach, wed manually select the relevant features of an image, such as edges or corners, in order to train the machine learning model.
- When choosing between machine learning and deep learning, you should ask yourself whether you have a high-performance GPU and lots of labeled data.
- But in a deep learning model, you need a large amount of data, which means the model can take a long time to train.
- By using deep learning as a feature extractor and machine learning to classify the features, you can get an accurate and flexible model.

- Lydia Rainforth, analyst at Barclays, says that use of digital technologies to – improve productivity is set to transform the big oil companies over the coming – decade.
- This is simply not sustainable and it is clear to us that a new way of working – is required, says Ms Rainforth, who estimates the value of the potential – productivity gains for European oil and gas majors at an annual $60bn.
