In 2017, the original (100M-sized) encoder-decoder transformer model was proposed in the "Attention is all you need" paper. At the time, the focus of the research was on improving seq2seq for machine translation , by removing its recurrence to process all tokens in parallel, but preserving its dot-product attention mechanism to keep its text ...
Already in spring 2017, even before the "Attention is all you need" preprint was published, one of the co-authors applied the "decoder-only" variation of the architecture to generate fictitious Wikipedia articles. [34] Transformer architecture is now used alongside many generative models that contribute to the ongoing AI boom.
For decoder self-attention, all-to-all attention is inappropriate, because during the autoregressive decoding process, the decoder cannot attend to future outputs that has yet to be decoded. This can be solved by forcing the attention weights = for all <, called "causal masking". This attention mechanism is the "causally masked self-attention".
In the theory, the claim about the presence of subjective experience depends on cognitive access to an internal model of attention. That internal model does not provide a scientifically precise description of attention, complete with the details of neurons, lateral inhibitory synapses, and competitive signals. The model is silent on the ...
James Webb: Born in NC, schooled at UNC-Chapel Hill. James Webb was born in 1906 and lived in rural Granville County, on the northern border of North Carolina. His father was the superintendent of ...
Additional research proposes the notion of a moveable filter. The multimode theory of attention combines physical and semantic inputs into one theory. Within this model, attention is assumed to be flexible, allowing different depths of perceptual analysis. [28] Which feature gathers awareness is dependent upon the person's needs at the time. [3]
The scarcity of attention is the underlying assumption for attention management; the researcher Herbert A. Simon pointed out that when there is a vast availability of information, attention becomes the more scarce resource as human beings cannot digest all the information. [6] Fundamentally, attention is limited by the processing power of the ...
Donald Broadbent's filter model is the earliest bottleneck theory of attention and served as a foundation for which Anne Treisman would later build her model of attenuation upon. [10] Broadbent proposed the idea that the mind could only work with so much sensory input at any given time, and as a result, there must be a filter that allows us to ...
