Topic

10.03.20 Sms Märt Möls Censoring and truncation - what they are; why to use; how to use?
25.02.20 Sms Jüri Lember In seminar today, we continue to study the very basic of Bayesian statistics. In the last seminar we saw that putting priors cmpletely changes the model even in the most simplest case.
The practitioners typically do not realize that, and so the outcome of Bayesian statistical analysis might be largely unexpected (because the mudel has been changed). This obviously raises an important question -- is there any point of doing  Bayesian statistics at all? To study that question, we performed a real data analysis on protein alignment data.

12.02.19 Sms Fabio Zucca (Milaano Polütehnikum) We generalize the evolution model introduced by Guiol, Machado and Schinazi (2010). In our model at odd times a random number X of species is created. Each species is endowed with a random fitness with arbitrary distribution on [0,1]. At even times a random number Y of species is removed, killing the species with lower fitness. We show that there is a critical fitness f_c below which the number of species hits zero i.o.~and above of which this number goes to infinity. We prove uniform convergence for the distribution of surviving species and describe the phenomena which could not be observed in previous works with uniformly distributed fitness.

Wider Bootstrap Confidence Interval. The estimation of the unknown parameter is the typical problem in applied statistics. It is obvious to raise the questions that 

* what estimator should be used and

* how accurate is the chosen estimator as an estimation of our parameter

The bootstrap is the general methodology to examine the accuracy of our estimator. It is a computer-based method first introduced by B. Efron in 1979. 

According to Efron, using skewness of the estimator it is possible to construct bootstrap confidence interval which is wider than standard confidence interval.

Pulsatility of small cortical veins using phase contrast magnetic resonance imaging at 7 Tesla.
Venous pulsatility measured from large cerebral veins has been shown to change in pathologies such as normal pressure hydrocephalus, Alzheimer’s disease, vascular dementia, mild cognitive impairment and multiple sclerosis. Venous pulsatility also increases with age. Recent improvements in the resolution of imaging techniques have made it feasible to explore smaller vessels. In my talk I give an overview of my Master’s project at the brain imaging centre of Cardiff University where, for the first time, we demonstrated the pulsatility of small cortical veins using phase-contrast magnetic resonance imaging at 7 tesla. Another very important finding was the statistically significant lag detected between the arrival of the cardiac pulse wave into the small cortical arteries and the small cortical veins. Measurements from smaller veins enhance the model of cerebral haemodynamics and add valuable insight into the medical conditions where intracranial pressure or pulsatility has been compromised, as well as into normal aging.

Stabiilse jaotuse parameetrite hindamine kumulantfunktsioonist. Stabiilsed jaotused moodustavad laia 4-parameetrilise tõenäosusjaotuste klassi. See eristati 1920ndatel kui sõltumatute sama jaotusega juhuslike suuruste normeeritud summa piirjaotus. Klass hõlmab nii kergete/raskete sabadega kui sümmeetrilised/asümmeetrilised juhud ja on leidnud ulatuslikku rakendust erinevates valdkondades. Stabiilse jaotuse parameetrite hindamise muudab keerukaks analüütilise jaotusfunktsiooni puudumine (välja arvatud erijuhud nagu  normaal-, Cauchy ja Levy jaotus). Viimastel aastakümnetel on  esitatud mitmeid lahendusi kuid neil kõigil on omad kitsendused. Käesoleva uurimus eesmärk on edasi arendada 1970ndatel välja pakutud üldistatud momentide meetodit.

Masinõppe algoritmide liigne enesekindlus ja kuidas seda vältida. Keerulised intelligentsed süsteemid nagu isesõitvad autod ja meditsiinilised ekspertsüsteemid rakendavad masinõppega ehitatud klassifikaatoreid. Tihti on tarvis, et need klassifikaatorid väljastaks koos ennustusega ka enesekindluse määra, sest see võimaldab süsteemil madala enesekindluse korral teha turvalisemaid valikuid. Seepärast on väga oluline, et klassifikaator ei oleks liiga enesekindel, sest see suurendaks väga kalliste vigade riski. Paraku on masinõppe meetoditega saadavad hinnangud siiski tihti liiga enesekindlad. Seminaris räägin millest see põhjustatud on ning kuidas kalibreerimise abil liigsest enesekindlusest lahti saada.
