In our research, we consider transfer learning scenarios where a target learner does not have access to the source data, but instead to hypotheses or models induced from it. This is called the Hypothesis Transfer Learning (HTL) problem. Previous approaches concentrated on transferring source hypotheses as a whole. We introduce a novel method for selectively transferring elements from previous h...

I have been an investigator on two NSF grants in the past five years, both as principal investigator: The original LLD proposal was for three years. As the LLD program was being phased out, the project was funded for one year and I was asked to submit a proposal to CCD to cover the remaining two years. Because of the uncertainty in the funding, it was difficult at first to find qualified gradua...

Identification of a second target is often impaired by the requirement to process a prior target in a rapid serial visual presentation (RSVP). This is termed the attentional blink. Even when the first target is task-irrelevant an attentional blink may occur providing this first target shares similar features with the second target (contingent capture). An RSVP experiment was undertaken to asses...

Several suggestions for a class of theories of recognition memory have been proposed during the past decade. These models address predictions about judgments of prior occurrence of an event, not the identification of what it is. The history and current status of one of these models is discussed. The model postulates the detection of familiarity and the utilization of retrieval mechanisms as add...

Data concerning frequency of cesarean section as well as frequency of vaginal delivery after cesarean section in Poznań region in years 1990-1991 were presented. During last years we observed significant increase of spontaneous deliveries after cesarean section. The indications for the previous cesarean section and the outcome of the present pregnancy are discussed.

Stereoscopic images in computer graphics applications often require two rendering passes reducing by half the frame rate. In this situation, the conversion from standard to stereoscopic images may involve some difficulties to maintain real time rendering if the geometry is made of thousands triangles. Since few years, auto-stereoscopic displays have become more and more popular because of their...

OBJECTIVES to evaluate the feasibility and long-term results of angioplasty and stenting in the treatment of restenosis following aortoiliac endarterectomy. MATERIALS AND METHODS between 1991 and 1999 19 patients underwent angioplasty with selective stenting for recurrent stenosis after previous aortoiliac endarterectomy. Aortic lesions were treated five times in four patients. At the iliac l...

Over a 9-yt'ar period, 58 patients who had pre"ious portasyslemic shunt procedures unden-ent orthotopic liver transplantation (OtTx) under a cyclosporine-steroid immunosuppresshe regimen. The types of shunt used were distal splenorenal (18 patients), mesocaval (17 patients). end-to-side portacaval (II patients). side-to-side portaca,'al (5 patients) and proximal splenorenal (7 patients). The me...
