CORINA, The Salk Institute and University of California, San Diego, Wednesday, April 24, 11:00 a.m., JRL S-118: Psycholinguistic and Connectionist Investigations of Syllable Structure: Implications for Language Representation The characterization of representations which underlie our knowledge and use of language has been a major concern of linguistic and psychological theories of language. However, the existence of specific representational categories are often assumed by the very theories which attempt to describe them. This leaves open the very important question of how language representations are instantiated. The present paper discusses this problem in relation to the representation of syllable structure. First, psycholinguistic data is presented which shows that the syllable serves as a useful guide in language recognition. This data provides support for the view that syllable structure is represented in the mental lexicon. Second, a series of Connectionist simulations are discussed which investigate the development of syllable structure. In one simulation a large natural language data base is used to show that in principle, representations of syllable structure may be derived from the regularities present in a language. A second simulation demonstrates how extracted representations may be used to guide a morpho- phonological process of syllable based reduplication. These results have important implications for theories of the mental lexicon and linguistic phonological representation. ------------------------------ To: nl-kr@cs.rpi.edu Date: Wed, 17 Apr 91 22:02:22 -0500 >From: David Lewis <lewis@tira.uchicago.edu> Subject: Machine Learning `91 conference announcement ML91 -- The Eighth International Workshop on Machine Learning Registration Information On behalf of the organizing committee, and the individual workshop committees, we are pleased to announce that ML91, the Eighth International Workshop on Machine Learning, will be held at Northwestern University, Evanston, Illinois, USA, June 27-29, 1991. ML91 comprises eight workshop tracks: o Automated Knowledge Acquisition o Computational Models of Human Learning o Constructive Induction o Learning from Theory and Data o Learning in Intelligent Information Retrieval o Learning Reaction Strategies o Learning Relations o Machine Learning in Engineering Automation In addition there will be plenary talks by noted researchers in machine learning and related fields. Registration The registration fee will be $70 for students, $100 for everyone else. This fee will cover conference participation, proceedings, and receptions. To register please send a check for the appropriate amount, made out to Northwestern University, along with a completed copy of the form to be found at the end of this message. The deadline for registration is May 22, 1991. After this date, a late fee of $25 will be charged. Accomodations We have reserved rooms at the following hotels: Omni Orrington Hotel 1710 Orrington Avenue Evanston, Illinois 60201 (708) 866-8700 or 1-800-THE-OMNI Rates: $78.00 single per night $88.00 double per night The Orrington is a five minute walk from the conference site. Holiday Inn -- Evanston 1501 Sherman Avenue Evanston, Illinois 60201 (708) 491-6400 or 1-800-HOLIDAY Rates: $60.00 single per night $70.00 double per night The Holiday Inn is a fifteen minute walk from the conference site. You must make hotel reservations yourself. When you reserve your room, please inform the hotel that you are registering for the Machine Learning Workshop. We are currently trying to arrange dorm space on campus. A message about this will be forthcoming shortly. Travel By air: Chicago has two airports: O'Hare and Midway. Most flights go to O'Hare, which is also the most convenient to Evanston. To get from O'Hare to Evanston, the following options are available: Taxi: The fare from O'Hare to Evanston should be about $25. Bus Service: Continental Air Tranport (312-454-7799) and Larry Webb Bus Service (312-866-7163) leave O'Hare for Evanston every hour from the American Airlines baggage area. Each line will take you to the Omni Orrington Hotel in Evanston. The Holiday Inn is 3 blocks south of the Orrington. Public Transportation: The CTA (1-800-972-7000) "El" trains run from O'Hare to downtown Chicago, and from Chicago to Evanston. Follow the airport signs to locate the O'Hare "El" stop. The fare is $1 per person. Take the "El" to the Washington St. stop, which is the end of the line. Transfer to a Northbound train. Take this train to the Howard St. Station. Transfer to a Northbound Evanston train. Get off at the Davis St. station in Evanston. To get to the Holiday Inn, walk east to Sherman Ave., turn right and go south two blocks. To get to the Orrington, walk east to Orrington Ave., turn left and go north one block. This trip will take at least an hour. It's reasonably safe but we don't recommend it because of the aggravation involved. By car: To get to Evanston, take Dempster St. east from either the Tri-State Tollway (I-294) or the Edens Expressway (I-94). Follow Dempster east to Chicago Ave. (one block past the "El" train overpass). Turn left on Chicago and go north. To get to the Holiday Inn, turn left on Grove St., go one block west. To get to the Orrington, turn left on Davis St., go one block west to Orrington, turn right and go one and a half blocks north to the hotel. By train: Amtrack trains stop at Union Station in downtown Chicago. Walk 4 blocks north on Canal St. to the Chicago & Northwestern Commuter Train Station. Take a Northbound train to the Davis St. station in Evanston. Directions from there to the hotels are as from the "El" above. **************************Registration Form************************** Please send this form, along with a check in the appropriate amount made out to Northwestern University, to the following address: Machine Learning 1991 The Institute for the Learning Sciences 1890 Maple Avenue Evanston, Illinois, 60201 USA phone (708) 491-3500 fax (708) 491-5258 email ml91@ils.nwu.edu Registration information (please type or print): Name: Address: Phone: Email: Type of registration: ( ) Student -- $70 ( ) Others -- $100 Registration is due May 22, 1991.
