Overview
This solution utilizes an Autoencoder model to learn and understand the data distribution which can fill in missing values once trained. Its objective is to classify the events based on the patterns and observations collected for data from multiple sensors. In production, the solution can handle missing information in sensor data and can still generate the correct classification for a given data point.
Highlights
- When dealing with multiple sensors as data sources, there might be interruptions to the data stream if one or more of them stop working at any point in time. A denoising autoencoder is modelled to learn the distribution of the data by training to recreate it identically so that it can account for these changes, ensuring the model can work sustainably despite any such issues with the devices. After training using data without missing values and with added synthetic masking noise, the developed model is robust to any such disappearances in the data.
- The trained model can be made use of for classification tasks with the incoming data which could be from a variety of sources. Even if the data is of different types arising from many different sensors, devices, machines or meters, this solution is designed to take this into consideration and give out accurate classification results. This finds its applications in various industries like IT infrastructure, production and manufacturing where key business decisions are based on the information collected from such sensors.

Inputs
- Summary
- A training data file with numerical columns and limited missing values should be provided. Along with this, a text file (.txt) containing the list of sensors is required with the sensor names matching the column names in the training and testing files.
- Include data with minimal null/missing values in the training file to ensure that the maximum amount of patterns can be learnt on this clean data. Test data can have a greater proportion of missing values.
- Input MIME type
- text/csv, text/plain, application/zip
Input data descriptions
The following table describes supported input data fields for real-time inference and batch transform.
Field name | Description | Constraints | Required |
|---|---|---|---|
train | • The input data should only be in numerical format. There should not be any columns of string data type.
• For the initial training data, there should be minimal null/missing values for optimal training performance on maximum clean data from which the model can learn necessary patterns
• Null values should not be present as empty strings (" ") as these will not be detected during the processing for this solution
• The expected target values should be present in a column named 'label' | Type: Continuous | Yes |
sensor_list | • Along with the training file, a text file named 'sensor_list.txt' needs to be uploaded which contains a list of sensors in a list format, eg. ['sensor_1', 'sensor_2', 'sensor_3'].
• The names of the sensors in this list should also be present in the column names to indicate which sensor a particular column belongs to. | Type: FreeText | Yes |
