Sensitivity estimates from characteristic functions
We investigate the application of the likelihood ratio method (LRM) for sensitivity estimation when the relevant density for the underlying model is known only through its charact...

Quaternionic wavelets for texture classification
This paper proposes a new texture classifier based on the Quaternionic Wavelet Transform (QWT). This recent transform separates the informations contained in the image better tha...

Hierarchical dictionary learning for invariant classification
Sparse representation theory has been increasingly used in the fields of signal processing and machine learning. The standard sparse models are not invariant to spatial transform...

Log-likelihood ratio clipping in MIMO-BICM systems: Information geometric analysis and impact on system capacity
The clipping of log-likelihood ratios (LLRs) in soft demodulators for multiple-input multiple-output (MIMO) systems with bitinterleaved coded modulation (BICM) was recently observ...
