چکیده

This paper considers communication in terms of inference about the behaviour of others (and our own behaviour). It is based on the premise that our sensations are largely generated by other agents like ourselves. This means, we are trying to infer how our sensations are caused by others, while they are trying to infer our behaviour: for example, in the dialogue between two speakers. We suggest that the infinite regress induced by modelling another agent - who is modelling you - can be finessed if you both possess the same model. In other words, the sensations caused by others and oneself are generated by the same process. This leads to a view of communication based upon a narrative that is shared by agents who are exchanging sensory signals. Crucially, this narrative transcends agency - and simply involves intermittently attending to and attenuating sensory input. Attending to sensations enables the shared narrative to predict the sensations generated by another (i.e. to listen), while attenuating sensory input enables one to articulate the narrative (i.e. to speak). This produces a reciprocal exchange of sensory signals that, formally, induces a generalised synchrony between internal (neuronal) brain states generating predictions in both agents. We develop the arguments behind this perspective, using an active (Bayesian) inference framework and offer some simulations (of birdsong) as proof of principle.

حذف کلاتر قوی دریا با استفاده از الگوریتم DUET BSS

Abstract- Suppressing clutter is one of the most crucial phases in radar signal processing. Also, Blind Source Separation (BSS) is one of the recent and very important problems in signal processing that shows its efficiency in many applications. Degenerate Unmixin Estimation Technique (DUET) is one of the Underdetermined BSS algorithms that separate sources from mixtures using only two mixtures...

Phase Aliasing Correction For Robust Blind Source Separation Using DUET

Degenerate Unmixing Estimation Technique (DUET) is a technique for blind source separation (BSS). Unlike the ICA based BSS techniques, DUET is a time-frequency scheme that relies on the socalled W-disjoint orthogonality (WDO) property of the source signals, which states that the windowed Fourier transforms of different source signals have statistically disjoint supports. In addition to being co...

جداسازی سیگنالهای صحبت مخلوط شده در یک محیط واقعی با استفاده از الگوریتم DUET ساده شده

الگوریتم تخمین جداسازی کاهنده(DUET)  از الگوریتمهای عملی‌ای است که جداسازی منابع در یک محیط بدون پژواک را انجام می‌دهد. این الگوریتم از حوزه فرکانس برای پردازش سیگنالها استفاده می‌کند و مخلوطهای صحبت را حتی وقتی تعداد منابع بیشتر از سنسورها باشد، جدا می‌کند. اما اجرای DUET، بخصوص برای فایلهای صحبت با طول نسبتا بزرگ، زمان‌بر و کند است. در این تحقیق ضمن کاهش نمونه‌برداری سیگنال صحبت مخلوطی که قرا...

The Duet Code of the Female Black-bellied Wren

In many duet-singing songbirds, paired birds combine their song types nonrandomly to form duet songs. Several different behavioral mechanisms could generate nonrandom song type associations in duets. I tested female Black-bellied Wrens (Thryothorus fasciatoventris) for one such mechanism: adherence to a set of rules linking female response songs to male stimulus songs. I call this set of rules ...

Mating success follows duet dancing in the Java sparrow

Mutual interactions between sexes have multiple signalling functions. Duet singing in songbirds is related to mutual mate guarding, joint resource defence, and signalling commitment. Coordinated visual displays of mating pairs are thought to perform similar functions, but are less well understood. The current study evaluated mutual interactions in an Estrildid species to explore the relative im...
