Comparing humans and AI agents
Comparing humans and machines is one important source of
information about both machine and human strengths and limitations.
Most of these comparisons and competitions are performed in rather
specific tasks such as calculus, speech recognition, translation, games,
etc. The information conveyed by these experiments is limited, since it
portrays that machines are much better than humans at some domains
and worse at others. In fact, CAPTCHAs exploit this fact. However,
there have only been a few proposals of general intelligence tests in the
last two decades, and, to our knowledge, just a couple of implementations
and evaluations. In this paper, we implement one of the most recent test
proposals, devise an interface for humans and use it to compare the
intelligence of humans and Q-learning, a popular reinforcement learning
algorithm. The results are highly informative in many ways, raising many
questions on the use of a (universal) distribution of environments, on the
role of measuring knowledge acquisition, and other issues, such as speed,
duration of the test, scalability, etc.We thank the anonymous reviewers for their helpful
comments. We also thank JosĆ© Antonio MartĆn H. for helping us with several

On more realistic environment distributions for defining, evaluating and developing intelligence
One insightful view of the notion of intelligence is the ability
to perform well in a diverse set of tasks, problems or environments. One of
the key issues is therefore the choice of this set, which can be formalised
as a `distributionĀæ. Formalising and properly defining this distribution is
an important challenge to understand what intelligence is and to achieve
artificial general intelligence (AGI). In this paper, we agree with previous
criticisms that a universal distribution using a reference universal Turing
machine (UTM) over tasks, environments, etc., is perhaps amuch too general
distribution, since, e.g., the probability of other agents appearing on
the scene or having some social interaction is almost 0 for many reference
UTMs. Instead, we propose the notion of Darwin-Wallace distribution for
environments, which is inspired by biological evolution, artificial life and
evolutionary computation. However, although enlightening about where
and how intelligence should excel, this distribution has so many options
and is uncomputable in so many ways that we certainly need a more practical
alternative. We propose the use of intelligence tests over multi-agent
systems, in such a way that agents with a certified level of intelligence at
a certain degree are used to construct the tests for the next degree. This
constructive methodology can then be used as a more realistic intelligence
test and also as a testbed for developing and evaluating AGI systems.We thank the anonymous reviewers for their helpful comments. We also thank the funding from the Spanish MEC and MICINN for projects

Comparison of Support Vector Machine and Back Propagation Neural Network in Evaluating the Enterprise Financial Distress
Recently, applying the novel data mining techniques for evaluating enterprise
financial distress has received much research alternation. Support Vector
Machine (SVM) and back propagation neural (BPN) network has been applied
successfully in many areas with excellent generalization results, such as rule
extraction, classification and evaluation. In this paper, a model based on SVM
with Gaussian RBF kernel is proposed here for enterprise financial distress
evaluation. BPN network is considered one of the simplest and are most general
methods used for supervised training of multilayered neural network. The
comparative results show that through the difference between the performance
measures is marginal; SVM gives higher precision and lower error rates.Comment: 13 pages, 1 figur
Philosophy of Computer Science: An Introductory Course
There are many branches of philosophy called āthe philosophy of X,ā where X = disciplines ranging from history to physics. The philosophy of artificial intelligence has a long history, and there are many courses and texts with that title. Surprisingly, the philosophy of computer science is not nearly as well-developed. This article proposes topics that might constitute the philosophy of computer science and describes a course covering those topics, along with suggested readings and assignments
On The Foundations of Digital Games
Computers have lead to a revolution in the games we play, and, following this, an interest for computer-based games has been sparked in research communities. However, this easily leads to the perception of a one-way direction of influence between that the field of game research and computer science. This historical investigation points towards a deep and intertwined relationship between research on games and the development of computers, giving a richer picture of both fields. While doing so, an overview of early game research is presented and an argument made that the
distinction between digital games and non-digital games may be counter-productive to game research as a whole
KBS for Desktop PC Troubleshooting
Abstract: Background: In spite of the fact that computers continue to improve in speed and functions operation, they remain complex to use. Problems frequently happen, and it is hard to resolve or find solutions for them. This paper outlines the significance and feasibility of building a desktop PC problems diagnosis system. The system gathers problem symptoms from usersā desktops, rather than the user describes his/her problems to primary search engines. It automatically searches global databases of problem symptoms and solutions, and also allows ordinary users to contribute exact problem reports in a structured manner. Objectives: The main goal of this Knowledge Based System is to get the suitable problem desktop PC symptoms and the correct way to solve the errors. Methods: In this paper the design of the proposed Knowledge Based System which was produced to help users of desktop PC in knowing many of the problems and error such as : Power supply problems, CPU errors, RAM dumping error, hard disk errors and bad sectors and suddenly restarting PC. The proposed Knowledge Based System presents an overview about desktop PC hardware errors are given, the cause of fault are outlined and the solution to the problems whenever possible is given out. CLIPS Knowledge Based System language was used for designing and implementing the proposed expert system. Results: The proposed PC desktop troubleshooting Knowledge Based System was evaluated by IT students and they were satisfied with its performance
Data-driven Soft Sensors in the Process Industry
In the last two decades Soft Sensors established themselves as a valuable alternative to the traditional means for the acquisition of critical process variables, process monitoring and other tasks which are related to process control. This paper discusses characteristics of the process industry data which are critical for the development of data-driven Soft Sensors. These characteristics are common to a large number of process industry fields, like the chemical industry, bioprocess industry, steel industry, etc. The focus of this work is put on the data-driven Soft Sensors because of their growing popularity, already demonstrated usefulness and huge, though yet not completely realised, potential. A comprehensive selection of case studies covering the three most important Soft Sensor application fields, a general introduction to the most popular Soft Sensor modelling techniques as well as a discussion of some open issues in the Soft Sensor development and maintenance and their possible solutions are the main contributions of this work
