Engineering Contradiction Analysis
1Measurement precision
If data is processed in floating point format, then processing precision is maintained, but processing speed decreases and computational complexity increases
Solution Approach 1:
The patent applies parameter changes by transitioning the data representation format from floating point to integer-based quantized format. This changes the numerical parameters used in computation, allowing the system to maintain acceptable precision while significantly improving processing speed and reducing computational complexity. The quantization process transforms continuous floating-point values into discrete integer values that can be processed more efficiently by hardware.
2Productivity
If quantization operations are applied at multiple points in the network, then processing speed improves, but device complexity and processing overhead increase
Solution Approach 1:
The patent merges quantization operations by determining a single shared set of quantization parameters that can be applied to multiple data paths simultaneously. Instead of performing separate quantization operations at each path, the system combines the quantization into a single operation using unified parameters, thereby reducing the total number of quantization operations and lowering computational complexity while maintaining processing speed benefits.
Solution Approach 2:
The patent implements universality by creating a shared set of quantization parameters that serve multiple functions across different data paths in the neural network. This single set of parameters is universally applicable to multiple paths, eliminating the need for path-specific quantization parameters and reducing the overall complexity of the quantization process while maintaining efficiency across the entire network.

AI summary
The performance of a neural network is improved by applying quantization to data at various points in the network. In an embodiment, a neural network includes two paths. A quantization is applied to each path, such that when an output from each path is combined, further quantization is not required. In an embodiment, the neural network is an autoencoder that includes at least one skip connection. In an embodiment, the system determines a set of quantization parameters based on the characteristics of the data in the primary path and in the skip connection, such that both network paths produce output data in the same fixed point format. As a result, the data from both network paths can be combined without requiring an additional quantization.
