1Productivity
If lossy compression is applied to reduce bandwidth, then network transmission efficiency is improved, but data quality degrades and classification accuracy decreases
Solution Approach 1:
A data enhancer model is introduced as an intermediary component between the lossy compressed data and the classification model. This data enhancer processes the degraded data to restore its quality before classification, thereby maintaining both network efficiency and classification accuracy. The data enhancer acts as a mediator that compensates for the quality loss introduced by compression.
Solution Approach 2:
The data enhancer is trained in advance using paired datasets of original and lossy compressed data to learn the inverse compression mapping. This preliminary training enables the data enhancer to automatically restore data quality when processing compressed inputs during deployment, without requiring real-time access to original data or iterative optimization.
2Measurement precision
If traditional decompression is used to restore data quality, then data accuracy is improved, but computational complexity and processing time increase
Solution Approach 1:
The patent replaces traditional mechanical decompression algorithms with a neural network-based data enhancer. This substitution leverages learned patterns from training data to perform quality restoration more efficiently than conventional signal processing methods, reducing computational complexity while maintaining or improving data accuracy.
Solution Approach 2:
The data enhancer transforms the problem from direct decompression to learning a mapping between compressed and original data spaces. By changing the approach parameters from algorithmic decomposition to neural network transformation, the system achieves better efficiency-accuracy tradeoff through learned representations rather than exhaustive computational methods.
3Loss of energy
If compression ratio is increased to maximize bandwidth utilization, then network resource efficiency is improved, but data distortion increases and model performance deteriorates
Solution Approach 1:
The system employs a feedback mechanism where the data enhancer is trained using the classification model's performance on compressed data as a guide. By monitoring classification accuracy and adjusting the data enhancement process accordingly, the system optimizes the balance between compression ratio and model performance, ensuring that network resources are utilized efficiently without sacrificing reliability.
Solution Approach 2:
The data enhancement process is designed to be adaptive to different compression levels and data types. The enhancer dynamically adjusts its processing based on the input characteristics, allowing the system to maintain optimal performance across varying compression ratios and network conditions, rather than using a fixed decompression approach.

AI summary
Techniques for enabling an ML classifier, which is trained on non-lossy data, to operate on lossy data without a reduction in performance are disclosed. Lossy data is received. A data enhancer is accessed. The data enhancer operates in conjunction with an ML classifier tasked with solving an end-task. The data enhancer treats the lossy data in a manner that prevents use of the lossy data by the ML classifier from introducing a bias into a classification operation performed by the ML classifier. In response to accessing treated lossy data from the data enhancer, the ML classifier performs the classification operation using the treated lossy data.
