Human game used for AI training Updated +Created
This section is about games initially designed for humans, but which ended up being used in AI development as well, e.g.:
Hund's rules Updated +Created
Allow us to determine with good approximation in a multi-electron atom which electron configuration have more energy. It is a bit like the Aufbau principle, but at a finer resolution.
Note that this is not trivial since there is no explicit solution to the Schrödinger equation for multi-electron atoms like there is for hydrogen.
For example, consider carbon which has electron configuration 1s2 2s2 2p2.
If we were to populate the 3 p-orbitals with two electrons with spins either up or down, which has more energy? E.g. of the following two:
m_L -1  0  1
    u_ u_ __
    u_ __ u_
    __ ud __
Hydrogen emission spectrum Updated +Created
HyperCard Updated +Created
This was the pre-Internet precursor of wikis. This program was likely venerable, shame it predates Ciro Santilli's era.
But the thing was much more bloated it seems, and also included visual programming elements, and WYSISYG UI creation.

IBM 700/7000 series Updated +Created
Illumina Updated +Created
The by far dominating DNA sequencing company of the late 2000's and 2010's due to having the smallest cost per base pair.
Illumina actually bought their 2010's dominating technology from a Cambridge company called Solexa.
To understand how Illumina's technology works basically, watch this video: Video 1. "Illumina Sequencing by Synthesis by Illumina (2016)".

The key innovation of this method is the Bridge amplification step, which produces a large amount of identical DNA strands.
ImageMagick Updated +Created

ImageNet1k download Updated +Created
To download from Kaggle, create an API token on kaggle.com, which downloads a kaggle.json file then:
mkdir -p ~/.kaggle
mv ~/down/kaggle.json ~/.kaggle
python3 -m pip install kaggle
kaggle competitions download -c imagenet-object-localization-challenge
The download speed is wildly server/limited and take A LOT of hours. Also, the tool does not seem able to pick up where you stopped last time.
Another download location appears to be: huggingface.co/datasets/imagenet-1k on Hugging Face, but you have to login due to their license terms. Once you login you have a very basic data explorer available: huggingface.co/datasets/imagenet-1k/viewer/default/train.
ImageNet Large Scale Visual Recognition Challenge dataset Updated +Created
Contains 1,281,167 images and exactly 1k categories which is why this dataset is also known as ImageNet1k: datascience.stackexchange.com/questions/47458/what-is-the-difference-between-imagenet-and-imagenet1k-how-to-download-it
www.kaggle.com/competitions/imagenet-object-localization-challenge/overview clarifies a bit further how the categories are inter-related according to WordNet relationships:
The 1000 object categories contain both internal nodes and leaf nodes of ImageNet, but do not overlap with each other.
image-net.org/challenges/LSVRC/2012/browse-synsets.php lists all 1k labels with their WordNet IDs.
n02119789: kit fox, Vulpes macrotis
n02100735: English setter
n02096294: Australian terrier
There is a bug on that page however towards the middle:
n03255030: dumbbell
href="ht:
n02102040: English springer, English springer spaniel
and there is one missing label if we ignore that dummy href= line. A thinkg of beauty!
Also the lines are not sorted by synset, if we do then the first three lines are:
n01440764: tench, Tinca tinca
n01443537: goldfish, Carassius auratus
n01484850: great white shark, white shark, man-eater, man-eating shark, Carcharodon carcharias
gist.github.com/aaronpolhamus/964a4411c0906315deb9f4a3723aac57 has lines of type:
n02119789 1 kit_fox
n02100735 2 English_setter
n02110185 3 Siberian_husky
therefore numbered on the exact same order as image-net.org/challenges/LSVRC/2012/browse-synsets.php
gist.github.com/yrevar/942d3a0ac09ec9e5eb3a lists all 1k labels as a plaintext file with their benchmark IDs.
{0: 'tench, Tinca tinca',
 1: 'goldfish, Carassius auratus',
 2: 'great white shark, white shark, man-eater, man-eating shark, Carcharodon carcharias',
therefore numbered on sorted order of image-net.org/challenges/LSVRC/2012/browse-synsets.php
The official line numbering in-benchmark-data can be seen at LOC_synset_mapping.txt, e.g. www.kaggle.com/competitions/imagenet-object-localization-challenge/data?select=LOC_synset_mapping.txt
n01440764 tench, Tinca tinca
n01443537 goldfish, Carassius auratus
n01484850 great white shark, white shark, man-eater, man-eating shark, Carcharodon carcharias
huggingface.co/datasets/imagenet-1k also has some useful metrics on the split:
Impact factor Updated +Created
This metric is so dumb! It only helps maintain existing closed journals closed! Why not just do a PageRank on the articles themselve instead? Like the h-index does for authors? That would make so much more sense!
Implicit metric signature in Einstein notation Updated +Created
Then a specific metric is involved, sometimes we want to automatically add it to products.
E.g., in a context considering the common Minkowski inner product matrix where the 4x4 matrix and is a vector in
which leads to the change of sign of some terms.
Implosion-type fission weapon Updated +Created
Implosion-type fission weapons are more complicated than gun-type fission weapon because you have to precisely coordinate the detonation of a bunch of explosives.
Indian classical music Updated +Created
This was Ciro Santilli's main study/work music for several years around 2020. Tabla rules.
Infinity (1996 film) Updated +Created
Good film, it feels quite realistic.
It is a shame that they tried to include some particularly interesting stories but didn't have the time to develop them, e.g. Feynman explaining to the high school interns what they were actually doing. These are referred to only in passing, and likely won't mean anything to someone who hasn't read the book.
The film settings are particularly good, and give what feels like an authentic view of the times. Particularly memorable are the Indian caves shown the film. TODO name? Possibly Puye Cliff Dwellings. Puye apparently appears prominently up on another film about Los Alamos: The Atomic city (1952). It is relatively close to Los Alamos, about 30 km away.
The title is presumably a reference to infinities in quantum field theory? Or just to the infinity of love etc.? But anyways, the infinities in quantum field theory theory come to mind if you are into this kind of stuff and is sad because that work started after the war.

Infrastructure as a service Updated +Created
You SSH into a an OS like Ubuntu and do whatever you want from there. E.g. Amazon EC2.
The OS is usually virualized, and you get only a certain share of the CPU by default.
Injective function Updated +Created
Mnemonic: in means into. So we are going into a codomain that is large enough so that we can have a different image for every input.
Innovate UK Updated +Created
In-order depth-first search Updated +Created
This is the order in which a binary search tree should be traversed for ordered output, i.e.:
This ordering makes sense for binary trees and not k-ary trees in general because if there are more than two nodes it is not clear what the top node should go in the middle of.
This is unlike pre-order depth-first search and post-order depth-first search which generalize obviously to general trees.
Instruction set architecture Updated +Created
The main interface between the central processing unit and software.
