Introduction. Even though R provides probably the most number of machine learning algorithms out there, its packages for application development are few and thus data scientists often find it difficult to push their deliverables to their organizations' production environments. As you have now experienced with a few simple steps, we were able to create web-endpoints that can be accessed locally. As an example, we will be training and deploying a simple text sentiment analysis service, using the IMDB reviews dataset (subsampled to 1000 examples).. We will achieve this by building the following architecture: Deploy machine learning models to production. h5py could also be an alternative. Most of the times, the real use of our Machine Learning model lies at the heart of a product – that maybe a small component of an automated mailer system or a chatbot. In computer science, in the context of data storage, serialization is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer, or transmitted across a network connection link) and reconstructed later in the same or another computer environment. The hello() method is responsible for producing an output (Welcome to machine learning model APIs!) By deploying models, other systems can send data to them and get their predictions, which are in turn populated back into the company systems. • Deploy trained models as API endpoints that automatically scale with demand. Django and React Tutorials; ... for example, we can set testing as initial status and then after testing period switch to production state. One such example of Web APIs offered is the Google Vision API. The algorithm can be something like (for example) a Random Forest, and the configuration details would be the coefficients calculated during model training. mnist), in some file location on the production machine. In this case, hitting a web-browser with localhost:5000/ will produce the intended output (provided the flask server is running on port 5000). Prathamesh Sarang works as a Data Scientist at Lemoxo Technologies. For the purpose of this blog post, I will define a model as: a combination of an algorithm and configuration details that can be used to make a new prediction based on a new set of input data.
