java.lang.Object
- org.nd4j.compression.impl.AbstractCompressor
- - org.nd4j.linalg.cpu.nativecpu.compression.CpuThreshold
  - - org.nd4j.linalg.cpu.nativecpu.compression.CpuFlexibleThreshold

All Implemented Interfaces:

NDArrayCompressor
```
public class CpuFlexibleThreshold
extends CpuThreshold
```
This compression is very special case, and shouldn't be ever used outside of ParallelWrapper/ParameterServer implementation. It encodes data as delta between zero and abs threshold. Unlike CpuThreshold codec, CpuFlexibleThreshold tries to target specified sparsity/density updates ratio via topN approach PLEASE NOTE: DO NOT USE THIS COMPRESSOR UNLESS YOU'RE 100% SURE WHAT YOU DO!

- Method Detail
  - getDescriptor
```
public java.lang.String getDescriptor()
```
    This method returns compression descriptor. It should be unique for any compressor implementation
    
    Specified by:
    
    getDescriptor in interface NDArrayCompressor
    
    Overrides:
    
    getDescriptor in class CpuThreshold
    
    Returns:
  - configure
```
public void configure(java.lang.Object... vars)
```
    This method allows you to configure desired sparsity/density ratio for updates. Pass it as float/double value Default value: 0.1
    
    Specified by:
    
    configure in interface NDArrayCompressor
    
    Overrides:
    
    configure in class CpuThreshold
    
    Parameters:
    
    vars -
  - compress
```
public DataBuffer compress(DataBuffer buffer)
```
    Specified by:
    
    compress in interface NDArrayCompressor
    
    Overrides:
    
    compress in class CpuThreshold
    
    Returns:
