Computational Learning Theory: New Models and Algorithms
Computational Learning Theory: New Models and Algorithms by Robert Hal Sloan S.M. EECS, Massachusetts Institute of Technology (1986) B.S. Mathematics, Yale University (1983) Submitted to the Department- of Electrical Engineering and Computer Science in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the MASSACHUSETTS INSTITUTE OF TECHNOLOGY June 1989 @ Robert Hal Sloan, 1989.

Signature of Author Department of Electrical Engineering and Computer Science May 23, 1989 Certified by Ronald L. Rivest Professor of Computer Science Thesis Supervisor Accepted by Arthur C. Smith Chairman, Departmental Committee on Graduate Students Abstract In the past several years, there has been a surge of interest in computational learning theory-the formal (as opposed to empirical) study of learning algorithms. One major cause for this interest was the model of probably approximately correct learning, or pac learning, introduced by Valiant in 1984. This thesis begins by presenting a new learning algorithm for a particular problem within that model: learning submodules of the free Z-module Zk. We prove that this algorithm achieves probable approximate correctness, and indeed, that it is within a log log factor of optimal in a related, but more stringent model of learning, on-line mistake bounded learning. We then proceed to examine the influence of noisy data on pac learning algorithms in general. Previously it has been shown that it is possible to tolerate large amounts of random classification noise, but only a very small amount of a very malicious sort of noise. -

Taitslin. Mikhail A. Taitslin passed away on July 20, 2013 in Tver, Russia, • where he had lived and worked for the last three decades of his life. He was a devoted husband and father, whose high-level research bridged areas of mathematics and computer science. He was a well-respected educator and mentor of students. Mikhail Taitslin was born into a family of medical research scientists on January 30, 1936 in Kiev, Ukraine. His father perished in WWII while serving as a doctor, and his mother raised their son alone. He received his undergraduate degree from the Lugansk Pedagogical Institute in 1957, and then started work as a school mathematics teacher while maintaining and developing an interest in higher mathematics. His continuing interest in higher mathematics led Taitslin to read a paper by Anatoly I. Maltsev, a leading Soviet algebraist and logician. The young mathematics teacher noticed an inaccuracy within the article of which he immediately wrote to the author. This started a correspondence between the young Taitslin and Maltsev which led to Taitslin’s move to the Ivanovo Pedagogical Institute, where Maltsev worked at the time. Later in 1960, he followed Maltsev to Akademgorodok, the newly opened scientific and educational centre in Novosibirsk. M.A. Taitslin earned his Ph.D in 1963, under the direction of Maltsev, and the Doctor of Sciences degree in 1968. -

It is here that heuristic search is discussed and classic programs such as SHRDLU and GPS are described. It is here that a sampling of Al material and its flavor as research is presented. Some of the material here is repeated without real analysis. For example, the author repeats the standard textbook mistake on the size of the chess space. On page 178, he states that 10120 is the size of this space, and uses this to suggest that no computer will ever play perfect chess. Actually, an estimate of 1040 is more realistic. If one considers that no chess board can have more than sixteen pieces of each color and there are many configurations that are illegal or equivalent, then the state space is reduced considerably. -

Project Abstract the Summer Program for Diversity in Logic for Undergraduates Builds Upon the PIKSI Summer Program Model, Focusi
Project Abstract The Summer Program for Diversity in Logic for Undergraduates builds upon the PIKSI Summer Program Model, focusing on Logic, an area in philosophy needing to increase diversity. We request seed funding for the pilot run of the program in May of 2016, when we will offer 12 students the opportunity to explore an exciting research theme in Logic –Paradoxes—receive small-group tutoring in formal techniques, receive mentoring and support for professionalization, experience validation, understanding and advice regarding diversity issues they have encountered –sexism, racism, ableism (and which the students may worry about encountering them in the profession), and develop a sense of community with students and faculty with whom they can identify and, in turn, come to strengthen their own identities. Project Purpose Our goal is to empower students to conceive of themselves as aspiring logicians, philosophers of logic and formal philosophers who belong in our profession. As Audrey Yap has noted, a majority of philosophy majors encounter some logic as a part of their undergraduate curriculum. Increasing diversity in logic is not simply a problem of exposure, but concretely addressing underlying pressures women and minority students experience, particularly stereotype threat and pernicious ideas about “natural aptitude.” (1) These pressures are especially strong in the subfield of logic, where almost no women and minorities have contributed to the research literature until very recently, and women and minorities remain underrepresented to a higher degree than in philosophy more broadly. Women and minorities learning logic can be vulnerable to feeling that a field like logic, that tends to be male and white dominated on the whole, is not welcoming to them. -

On the Automated Verification of Web Applications with Embedded
On the automated verification of web applications with embedded SQL Shachar Itzhaky1, Tomer Kotek2, Noam Rinetzky3, Mooly Sagiv3, Orr Tamir3, Helmut Veith2, and Florian Zuleger2 1 Massachusetts Institute of Technology 2 Vienna University of Technology 3 Tel Aviv University Abstract A large number of web applications is based on a relational database together with a program, typically a script, that enables the user to interact with the database through embedded SQL queries and commands. In this paper, we introduce a method for formal automated verification of such systems which connects database theory to mainstream program analysis. We identify a fragment of SQL which captures the behavior of the queries in our case studies, is algorithmically decidable, and facilitates the construction of weakest preconditions. Thus, we can integrate the analysis of SQL queries into a program analysis tool chain. To this end, we implement a new decision procedure for the SQL fragment that we introduce. We demonstrate practical applicability of our results with three case studies, a web administrator, a simple firewall, and a conference management system. 1998 ACM Subject Classification D.3.2 Database Management Languages, F.3.1 Specifying and Verifying and Reasoning about Programs Keywords and phrases SQL; Scripting language; Web services; Program verification; Two- variable fragment of First Order logic; Decidability; Reasoning Digital Object Identifier 10.4230/LIPIcs.xxx.yyy.p 1 Introduction Web applications are often written in a scripting language such as PHP and store their data in a relational database which they access using SQL queries and data-manipulating commands [36]. This combination facilitates fast development of web applications, which exploit the reliability and efficiency of the underlying database engine and use the flexibility of the script language to interact with the user. -
