Prediction process example
Simple data model design
Model creation using previous data or similar sensors models already existing .
Next data prediction
We use our computed model to predict the next data message.
Compute average difference
We compute the average difference that this sensor is used to send (e. g: + or - 2°C)
Data controls
At this step we liken received data with the computed one reflecting the data average.
Throw alert
If the previous step show an inconsistent data, an alert is thrown.
Popular algorithms used
K-Nearest Neighbour
A light weight computing resources way to find out if a received data is consistent regarding an cluster of data.
Feedforward Neural Network
These heavies algorithms are slow, need to be trained and a lot of computing resources but could discover quality of data and data schema with a great efficiency.
K-Means Clustering
K-Means clustering are used to compare data segment instead of isolate data to look for global sensors behaviours.
