WHY ARE BOTH LEGS OF THE SAME LENGTH ?

Why block-length and delay are not the same thing

Classically, information theorists have understood the tradeoff between delay and system error performance by using block-length as a proxy. Although this turns out to be correct when feedback is absent, it is shown to be very misleading when feedback is available. For symmetric channels, fixed block-length communication systems show no improvements in their error exponents while fixed delay sy...

Why delay and block length are not the same thing for channel coding with feedback

Classically, information theorists have understood the tradeoff between delay and system error performance by using block-length as a proxy. Although this turns out to be correct when feedback is absent, it is shown to be very misleading when feedback is available. For symmetric channels, fixed blocklength communication systems show no improvements in their error exponents while fixed delay sys...

Of Politicians and Technocrats, and Why Global Health Scholars Are Inevitably a Bit of Both: A Response to Recent Commentaries

Queues Are Spaces - Yet Still Both Are Not The Same?

This paper compares two different paradigms for machine-tomachine communication: messaging and space-based communication. As with human communication, one can distinguish between message-based, directed communication (email – abstracted into “messaging”) on the one hand, and anonymous communication based on persistent publication (Web – abstracted into “spaces”) on the other. However, despite t...

Why Neural Translations are the Right Length

We investigate how neural, encoder-decoder translation systems output target strings of appropriate lengths, finding that a collection of hidden units learns to explicitly implement this functionality.
