Concepts We Live By
The essence of metaphor is understanding and experiencing one kind of thing in terms of another.

Comparison to other Approaches
Treelets vs. semantic networks First, standard semantic networks are extremely vulnerable to what we might call the damaged-grandmother-node problem. If a single grandmother node is a physical part... -
Proposals for Implementing Recursive Combinations in a Neural Substrate
1. ExternalSystemsThatCanRepresentRecursiveStructure two common external systems for representing recursive combinations, numbers, and sentences. Consider first the decimal number scheme. This syst... -
Structured Knowledge in Multilayer Perceptrons
The idea that the mind represents explicit, recursive structured combinations of elements has been challenged in two related but distinct ways. 1. A geometrical conception: P. M. Churchland (1986) ... -
Evaluating competing models
3 criteria for evaluating competing models: 1. a model should be able to add -ed freely to novel words, even those with unfamiliar sounds. 2. An adequate model should produce defaultlike effects ev... -

Registers
Memory? A limitation of the binding schemes discussed so far is that none pro- vides a way of storing a binding. The bindings that are created are all entirely transitory, commonly taken to be cons... -
Tensor Products
proposed by Smolensky (1990) (大佬就在隔壁_(:_」∠)_ A tensor product is a way of representing a binding between a variable and an instance. A tensor product is not (by itself) a way of representi... -
Alternative ways of representing bindings between variables and instances
Cases in which humans can freely generalize UQOTOM on the basis of restricted data are problematic for multiple-nodes-per-variable multi-layer perceptrons trained by back-propagation. But this does... -
Multilayer Perceptrons and Operations over Variables
As it happens, many models that allocate just one node per variable rely on continuously varying input nodes rather than binary input nodes (analog encoding), whereas models that use multiple nodes... -
UQOTOM
Universally quantified one-toone-mappings (UQOTOM) Two particularly important functions that are both universally quantified and one-to-one are identity (f(x) = x) and concatention (f(x,y) = xy. Al... -
Symbols, symbol-manipulators, and Multiplayer perceptrons
The trouble is that there are too many different ways of defining what is meant by a symbol. Advocates of symbol-manipulation assume that there is something analogous to external symbols (words, st... -
Evaluation of preliminary connsiderations
None of the preliminary considerations that apparently favor multilayer perceptions -- biological plausibility, universal function approximation, and the like -- is actually decisive. Instead, as i... -

hmmm Most people associate the term (connectionnism) with the researchers who have most directly challenged the symbol-manipulation hypothesis, but the field of connectionism also encompasses model... -
Preface
But I am not an anti-connectionist; I am opposed only to a particular subset of the possible connectionnist models. The problem is that the term connectionism has become synonymous with a sinngle k...

Highlight the important stuff • Bold, italics, and underlining: Use for titles, labels, captions, and short word sequences to differentiate elements. Bolding is generally preferred over italics ... -
Color
Resist the urge to use color for the sake of being colorful; instead, leverage color selectively as a strategic tool to highlight the important parts of your visual. The use of color should always ... -
When redundant details shouldn’t be considered clutter
hmmm确实,想到了我之前的图,似乎应该改一下。 I’ve seen cases where the title of the visual indicates the values are dollars but the dollar signs aren’t included with the actual numbers in the tab... -
Clutter
What matters most when it comes to our visual communications is the perceived cognitive load on the part of our audience: how hard they believe they are going to have to work to get the information... -
To be avoided
There are also some specific graph types and elements that you should avoid: pie charts, donut charts, 3D, and secondary y‐axes. It is also worth noting that when you display two datasets against ... -
