Measuring the Progress of AI Research¶
This pilot project collects problems and metrics/datasets from the AI research literature, and tracks progress on them.
You can use this Notebook to see how things are progressing in specific subfields or AI/ML as a whole, as a place to report new results you've obtained, as a place to look for problems that might benefit from having new datasets/metrics designed for them, or as a source to build on for data science projects.
At EFF, we're ultimately most interested in how this data can influence our understanding of the likely implications of AI. To begin with, we're focused on gathering it.

Taxonomy¶
It collates data with the following structure:
problem
\ \
\ metrics - measures
\
- subproblems
\
metrics
\
measure[ment]sProblems describe the ability to learn an important category of task.
Metrics should ideally be formulated in the form "software is able to learn to do X given training data of type Y". In some cases X is the interesting part, but sometimes also Y.
Measurements are the score that a specific instance of a specific algorithm was able to get on a Metric.
problems are tagged with attributes: eg, vision, abstract-games, language, world-modelling, safety
Some of these are about performance relative to humans (which is of course a very arbitrary standard, but one we're familiar with)
- agi -- most capable humans can do this, so AGIs can do this (note it's conceivable that an agent might pass the Turing test before all of these are won)
- super -- the very best humans can do this, or human organisations can do this
- verysuper -- neither humans nor human orgs can presently do this
problems can have "subproblems", including simpler cases and preconditions for solving the problem in general
a "metric" is one way of measuring progress on a problem, commonly associated with a test dataset. There will often be several metrics for a given problem, but in some cases we'll start out with zero metrics and will need to start proposing some...
a measure[ment] is a score on a given metric, by a particular codebase/team/project, at a particular time
The present state of the actual taxonomy is at the bottom of this notebook.
Source Code¶
- Code implementing the taxonomy of Problems and subproblems, Metrics and Measurements is defined in a free-standing Python file, taxonomy.py. scales.py contains definitions of various unit systems used by
Metrics. Most source data is now defined in a series of separate files by topic:
- data/vision.py for hand-entered computer vision data
- data/language.py for hand-entered and merged language data
- data/strategy_games.py for data on abstract strategy games
- data/video_games.py a combination of hand-entered and scraped Atari data (other video game data can also go here)
data/stem.py for data on scientific & technical problems
data imported from specific scrapers (and then subsequently edited):
- Are We There Yet? image data, generated by
scrapers/awty.pybut then edited by hand
- Are We There Yet? image data, generated by
- For now, some of the
Problems andMetrics are still defined in this Notebook, especially in areas that do not have many active results yet.
- Scrapers for specific data sources:
- scrapers/awty.py for importing data from Rodriguo Benenson's Are We There Yey? site
- scrapers/es.py for processing a pasted table of data from the Evolutionary Strategies Atari paper (is probably a useful model for other Atari papers).

Problems, Metrics, and Datasets¶
Vision¶
The simplest vision subproblem is probably image classification, which determines what objects are present in a picture. From 2010-2017, Imagenet has been a closely watched contest for progress in this domain.
Image classification includes not only recognising single things within an image, but localising them and essentially specifying which pixels are which object. MSRC-21 is a metric that is specifically for that task:
from data.vision import *
imagenet.graph()
from data.vision import *
from data.awty import *
for m in sorted(image_classification.metrics, key=lambda m:m.name):
if m != imagenet: m.graph()

Visual Question Answering¶
Comprehending an image involves more than recognising what objects or entities are within it, but recognising events, relationships, and context from the image. This problem requires both sophisticated image recognition, language, world-modelling, and "image comprehension". There are several datasets in use. The illustration is from VQA, which was generated by asking Amazon Mechanical Turk workers to propose questions about photos from Microsoft's COCO image collection.
plot = vqa_real_oe.graph(keep=True, title="COCO Visual Question Answersing (VQA) real open ended", llabel="VQA 1.0")
vqa2_real_oe.graph(reuse=plot, llabel="VQA 2.0", fcol="#00a0a0", pcol="#a000a0")
for m in image_comprehension.metrics:
m.graph() if not m.graphed else None
HTML(image_comprehension.tables())
Game Playing¶
In principle, games are a sufficiently open-ended framework that all of intelligence could be captured within them. We can imagine a "ladder of games" which grow in sophistication and complexity, from simple strategy and arcade games to others which require very sophisticated language, world-modelling, vision and reasoning ability. At present, published reinforcement agents are climbing the first few rungs of this ladder.
Abstract Strategy Games¶
As an easier case, abstract games like chess, go, checkers etc can be played with no knowldege of the human world or physics. Although this domain has largely been solved to super-human performance levels, there are a few ends that need to be tied up, especially in terms of having agents learn rules for arbitrary abstract games effectively given various plausible starting points (eg, textual descriptions of the rules or examples of correct play).
from data.strategy_games import *
computer_chess.graph()
HTML(computer_chess.table())
Real-time video games¶
Computer and video games are a very open-ended domain. It is possible that some existing or future games could be so elaborate that they are "AI complete". In the mean time, a lot of interesting progress is likely in exploring the "ladder of games" of increasing complexity on various fronts.
Atari 2600¶
Atari 2600 games have been a popular target for reinforcement learning, especially at DeepMind and OpenAI. RL agents now play most but not all of these games better than humans.
In the Atari 2600 data, the label "noop" indicates the game was played with a random number, up to 30, of "no-op" moves at the beginning, while the "hs" label indicates that the starting condition was a state sampled from 100 games played by expert human players. These forms of randomisation give RL systems a diversity of game states to learn from.

Instrumentals recognition¶
Instrumentals recognition in a representative musical dataset for Instrumentals playlist generation.
- Experiments tested on SATIN database from Bayle et al. (2017).
- The ratio Instrumentals/Songs (11%/89%) of SATIN is representative of real uneven musical databases.
- The human performance is at 99% of correct instrumentals detection because there are known examples of possible confusion.

Image Generation¶

HTML(image_generation_metric.table())
Language Modelling and Comprehension¶
Text compression is one way to see how well machine learning systems are able to model human language. Shannon's classic 1951 paper obtained an expiermental measure of human text compression performance at 0.6 - 1.3 bits per character: humans know, better than classic algorithms, what word is likely to come next in a piece of writing. More recent work (Moradi 1998, Cover 1978) provides estimates that are text-relative and in the 1.3 bits per character (and for some texts, much higher) range.
from data.language import *

HTML(ptperplexity.table())
hp_compression.graph()
HTML(hp_compression.table())
LAMBADA is a challenging language modelling dataset in which the model has to predict a next word in a discourse, when that exact word has not occurred in the test. For instance, given a context like this:
He shook his head, took a step back and held his hands up as he tried to smile without losing a cigarette. “Yes you can,” Julia said in a reassuring voice. “I’ve already focused on my friend. You just have to click the shutter, on top, here.”
And a target sentence:
He nodded sheepishly, through his cigarette away and took the _________.
The task is to guess the target word "camera".
lambada.graph()
# Also consider adding the Microsoft Sentence Completion Challenge; see eg http://www.fit.vutbr.cz/~imikolov/rnnlm/thesis.pdf table 7.4
Translation¶
Translation is a tricky problem to score, since ultimately it is human comprehension or judgement that determines whether a translation is accurate. Google for instance uses human evaluation to determine when their algorithms have improved. But that kind of measurement is expensive and difficult to replicate accurately, so automated scoring metrics are also widely used in the field. Perhaps the most common of these are BLEU scores for corpora that have extensive professional human translations, which forms the basis for the measurements included here:
en_fr_bleu.graph()
en_de_bleu.graph()
en_ro_bleu.graph()
HTML(translation.tables())
Conversation: Chatbots & Conversational Agents¶
Conversation is the classic AI progress measure! There is the Turing test, which involves a human judge trying to tell the difference between a humand and computer that they are chatting to online, and also easier variants of the Turing test in which the judge limits themselves to more casual, less probing conversation in various ways.
The Loebner Prize is an annual event that runs a somewhat easier version of the test. Since 2014, the event has also been giving standard-form tests to their entrants, and scoring the results (each question gets a plausible/semi-plausible/implausible rating). This metric is not stable, because the test questions have to change every year, they are somewhat indicative of progress. Ideally the event might apply each year's test questions to the most successful entrants from prior years. Here is an example from 2016:
loebner.graph()
HTML(loebner.table())
Reading Comprehension¶
The Facebook BABI 20 QA dataset is an example of a basic reading comprehension task. It has been solved with large training datasets (10,000 examples per task) but not with a smaller training dataset of 1,000 examples for each of the 20 categories of tasks. It involves learning to answer simple reasoning questions like these:
There are numerous other reading comprehension metrics that are in various ways harder than bAbi 20 QA. They are generally not solved, though progress is fairly promising.
for m in reading_comprehension.metrics: m.graphed = False
plot = bAbi1k.graph(keep=True, title="bAbi 20 QA reading comprehension", llabel="1k training examples")
bAbi10k.target = None
bAbi10k.graph(reuse=plot, llabel="10k training examples", fcol="#00a0a0", pcol="#a000a0")
bAbi10k.target = bAbi1k.target
Another reading comprehension dataset that has received significant recent attention is the Stanford Question Answering Dataset (SQuAD). The literature reports both F1 scores and exact match scores, though these are closely correlated:
from data.language import *
plot = squad_f1.graph(keep=True, title="Stanford Question Answering Dataset (SQuAD)", tcol="g", llabel="F1 score")
squad_em.graph(reuse=plot, llabel="Exact Match (EM)", fcol="#00a0a0", pcol="#a000a0", tcol="#00a0a0")
for m in reading_comprehension.metrics:
if not m.graphed: m.graph()
HTML(reading_comprehension.tables())
Scientific and Technical capabilities¶
Arguably reading and understanding scientific, technical, engineering and medical documents would be taxonomically related to general reading comprehension, but these technical tasks are probably much more difficult, and will certainly be solved with separate efforts. So we classify them separately for now. We also classify some of these problems as superintelligent, because only a tiny fraction of humans can read STEM papers, and only a miniscule fraction of humans are capable of reasonably comprehending STEM papers across a large range of fields.
from data.stem import *

Generating computer programs from specifications
A particularly interesting technical problem, which may be slightly harder than problems with very clear constraints like circuit design, is generating computer programs from natural language specifications (which will often contain ambiguities of various sorts). This is presently a very unsolved problem, though there is now at least one good metric / dataset for it, which is [Deepmind's "card2code" dataset](https://github.com/deepmind/card2code) of Magic the Gathering and Hearthstone cards, along with Java and Python implementations (respectively) of the logic on the cards. Shown below is a figure from [_Ling, et al. 2016_](https://arxiv.org/abs/1603.06744v1) with their Latent Predictor Networks generating part of the code output for a Hearthstone card:

HTML(card2code_hs_acc.table())
Answering Science Exam Questions¶
Science exam question answering is a multifaceted task that pushes the limits of artificial intelligence. As indicated by the example questions pictured, successful science exam QA requires natural language understanding, reasoning, situational modeling, and commonsense knowledge; a challenge problem for which information-retrieval methods alone are not sufficient to earn a "passing" grade.
The [AI2 Science Questions](http://data.allenai.org/ai2-science-questions/) dataset provided by the Allen Institute for Artificial Intelligence (AI2) is a freely available collection of 5,059 real science exam questions derived from a variety of regional and state science exams. Project Aristo at AI2 is focused on the task of science question answering – the Aristo system is composed of a suite of various knowledge extraction methods, diagram processing tools, and solvers. As a reference point, the system currently achieves the following scores on these sets of non-diagram multiple choice (NDMC) and diagram multiple choice (DMC) science questions at two different grade levels. Allen Institute staff [claim these states of the art](https://github.com/AI-metrics/AI-metrics/pull/60) for Aristo [Scores are listed as "Subset (Train/Dev/Test)"]:
- Elementary NDMC (63.2/60.2/61.3)
- Elementary DMC (41.8/41.3/36.3)
- Middle School NDMC (55.5/57.6/57.9)
- Middle School DMC (38.4/35.3/34.3)
Another science question answering dataset that has been studied in the literature is based specifically on New York Regents 4th grade science exam tests:

Learning to Learn¶
Generalisation and Transfer Learning¶
ML systems are making strong progress at solving specific problems with sufficient training data. But we know that humans are capable of transfer learning -- applying things they've learned from one context, with appropriate variation, to another context. Humans are also very general; rather than just being taught to perform specific tasks, a single agent is able to do a very wide range of tasks, learning new things or not as required by the situation.

Safety and Security Problems¶
The notion of "safety" for AI and ML systems can encompass many things. In some cases it's about ensuring that the system meets various sorts of constraints, either in general or for specifically safety-critical purposes, such as correct detection of pedestrians for self driving cars.

# safe exploration may be related to one shot learning, though it's probably too early to mark that so clearly.
The work by Saunders et al. (2017) is an example of attempting to deal with the safe exploration problem by human-in-the-loop supervision. Without this oversight, a reinforcement learning system may engage in "reward hacking" in some Atari games. For instance in the Atari 2600 Road Runner game, an RL agent may deliberately kill itself to stay on level 1, because it can get more points on that level than it can on level 2 (particularly when it has not yet learned to master level 2). Human oversight overcomes this problem:

Automated Hacking Systems¶
Automated tools are becoming increasingly effective both for offensive and defensive computer security purposes.
On the defensive side, fuzzers and static analysis tools have been used for some time by well-resourced software development teams to reduce the number of vulnerabilities in the code they ship.
Assisting both offense and defense, DARPA has recently started running the Cyber Grand Challenge contest to measure and improve the ability of agents to either break into systems or defend those same systems against vulnerabilities. It isn't necessarily clear how such initiatives would change the security of various systems.
This section includes some clear AI problems (like learning to find exploitable vulnerabilities in code) and some less pure AI problems, such as ensuring that defensive versions of this technology (whether in the form of fuzzers, IPSes, or other things) are deployed on all critical systems.

Pedestrian Detection¶
Detecting pedestrians from images or video is a specific image classification problem that has received a lot of attention because of its importance for self-driving vehicles. Many metrics in this space are based on the Caltech pedestrians toolkit, thought the KITTI Vision Benchmark goes beyond that to include cars and cyclists in addition to pedestrians. We may want to write scrapers for Caltech's published results and KITTI's live results table.

# TODO: import data from these pedestrian datasets/metrics.
# performance on them is a frontier of miss rate / false positive tradeoffs,

Fairness and Debiasing¶
Biased decision making is a problem exhibited both by very simple machine learning classifiers as well as much more complicated ones. Large drivers of this problem include omitted-variable bias, reliance on inherently biased data sources for training data, attempts to make predictions from insufficient quantities of data, and deploying systems that create real-world incentives that change the behaviour they were measuring (see Goodhart's Law).
These problems are severe and widespread in the deployment of scoring and machine learning systems in contexts that include criminal justice, education policy, insurance and lending.
avoiding_bias = Problem("Build systems which can recognise and avoid biases decision making", ["safety"])
avoiding_bias.notes = """
Legally institutionalised protected categories represent only the most extreme and socially recognised
forms of biased decisionmaking. Attentive human decision makers are sometime capable of recognising
and avoiding many more subtle biases. This problem tracks AI systems' ability to do likewise.
"""

avoid_classification_biases.notes = '''
Several standards are available for avoiding classification biases.
They include holding false-positive / false adverse prediction rates constant across protected categories (which roughly maps
to "equal opportunity"), holding both false-positive and false-negative rates equal ("demographic parity"), and ensuring
that the fraction of each protected group that receives a given prediction is constant across all groups
(roughly equivalent to "affirmative action").'''

Privacy¶
Many of the interesting privacy problems that will arise from AI and machine learning will come from choices about the applications of the technology, rather than a lack of algorithmic progress within the field. But there are some exceptions, which we will track here.

avoid_privacy_bias.notes = """

group will be more difficult, because they are in many respects harder to identify.

How to contribute to this notebook¶
This notebook is an open source, community effort. It lives on Github at https://github.com/AI-metrics/AI-metrics. You can help by adding new metrics, data and problems to it! If you're feeling ambitious you can also improve its semantics or build new analyses into it. Here are some high level tips on how to do that.
0. The easiest way -- just hit the edit button¶
Next to every table of results (not yet next to the graphs) you'll find an "Add/edit data on Github" link. You can just click it, and you should get a link to the Github's online editor that should make it easy to add new results, or fix existing ones, and send us a pull request. For best results, make sure you're logged in to Github
1. If you're comfortable with git and Jupyter Notebooks, or are happy to learn¶
If you're interested in making more extensive changes to the Notebook, and you've already worked a lot with git and IPython/Jupyter Notebooks, you can run and edit copy locally. This is a fairly involved process (Jupyter Notebook and git interact in a somewhat complicated way) but here's a quick list of things that should mostly work:
- Install Jupyter Notebook and git.
- On an Ubuntu or Debian system, you can do:
sudo apt-get install git sudo apt-get install ipython-notebook || sudo apt-get install jupyter-notebook || sudo apt-get install python-notebook
- Make sure you have IPython Notebook version 3 or higher. If your OS
doesn't provide it, you might need to enable backports, or use
pipto install it.
- On an Ubuntu or Debian system, you can do:
- Install this notebook's Python dependencies:
- On Ubuntu or Debian, do:
sudo apt-get install python-{cssselect,lxml,matplotlib{,-venn},numpy,requests,seaborn} - On other systems, use your native OS packages, or use
pip:pip install cssselect lxml matplotlib{,-venn} numpy requests seaborn
- On Ubuntu or Debian, do:
- Fork our repo on github: https://github.com/AI-metrics/AI-metrics#fork-destination-box
- Clone the repo on your machine, and
cdinto the directory it's using - Configure your copy of git to use IPython Notebook merge filters to prevent conflicts when multiple people edit the Notebook simultaneously. You can do that with these two commands in the cloned repo:
git config --file .gitconfig filter.clean_ipynb.clean $PWD/ipynb_drop_output
git config --file .gitconfig filter.clean_ipynb.smudge cat
Run Jupyter Notebok in the project directory (the command may be
ipython notebook,jupyter notebook,jupyter-notebook, orpython notebookdepending on your system), then go to localhost:8888 and edit the Notebook to your heart's contentSave and commit your work (
git commit -a -m "DESCRIPTION OF WHAT YOU CHANGED")- Push it to your remote repo
- Send us a pull request!
Notes on importing data¶
- Each
.measure()call is a data point of a specific algorithm on a specific metric/dataset. Thus one paper will often produce multiple measurements on multiple metrics. It's most important to enter results that were at or near the frontier of best performance on the date they were published. This isn't a strict requirement, though; it's nice to have a sense of the performance of the field, or of algorithms that are otherwise notable even if they aren't the frontier for a sepcific problem. - When multiple revisions of a paper (typically on arXiv) have the same results on some metric, use the date of the first version (the CBTest results in this paper are an example)
- When subsequent revisions of a paper improve on the original results (example), use the date and scores of the first results, or if each revision is interesting / on the frontier of best performance, include each paper
- We didn't check this carefully for our first ~100 measurement data points :(. In order to denote when we've checked which revision of an arXiv preprint first published a result, cite the specific version (https://arxiv.org/abs/1606.01549v3 rather than https://arxiv.org/abs/1606.01549). That way, we can see which previous entries should be double-checked for this form of inaccuracy.
- Where possible, use a clear short name or acronym for each algorithm. The full paper name can go in the
papernamefield (and is auto-populated for some papers). When matplotlib 2.1 ships we may be able to get nice rollovers with metadata like this. Or perhaps we can switch to D3 to get that type of interactivity.
What to work on¶
- If you know of ML datasets/metrics that aren't included yet, add them
- If there are papers with interesting results for metrics that aren't included, add them
- If you know of important problems that humans can solve, and machine learning systems may or may not yet be able to, and they're missing from our taxonomy, you can propose them
- Look at our Github issue list, perhaps starting with those tagged as good volunteer tasks.
