It is quite obvious that ML teams developing new models or algorithms expect that the performance of the model on test data will be optimal. But many times that just doesn't happen. The above list is not exhaustive though. In this article, we'll discuss the process which can solve multiple above-mentioned problems and ML teams be very mindful while executing it. It is widely accepted in the machine learning community that preprocessing data is an important step in the ML workflow and it can improve the performance of the model. "A study by Bezdek et al. (1984) found that preprocessing the data improved the accuracy of several clustering algorithms by up to 50%." "A study by Chollet (2018) found that data preprocessing techniques such as data normalization and data augmentation can improve the performance of deep learning models."

This screencast shows how to use Skymind's DataVec to ingest Comma Separated Values from a text file, convert the fields to numeric using a DataVec Transform Process in Spark, and save the modified data. Transforming non-numeric data to numeric data is a key preliminary step to using a Neural Network to analyze the data.

Developing intelligent systems requires combining results from both industry and academia. In this report you find an overview of relevant research fields and industrially applicable technologies for building very large scale cyber physical systems. A concept architecture is used to illustrate how existing pieces may fit together, and the maturity of the subsystems is estimated. The goal is to structure the developments and the challenge of machine intelligence for Consumer and Industrial Internet technologists, cyber physical systems researchers and people interested in the convergence of data & Internet of Things. It can be used for planning developments of intelligent systems.
