Calibration of machine scores for pronunciation grading
Our proposed paradigm for automatic assessment of pronunciation quality uses hidden Markov models (HMMs) to generate phonetic segmentations of the student’s speech. From these segmentations, we use the HMMs to obtain spectral match and duration scores. In this work we focus on the problem of calibrating different machine scores to obtain an accurate prediction of the grades that a human expert ...
متن کاملCombined Visual and Machine Strength Grading
The aim of this study was to show the possibility of the classification of structural timber (European spruce) into strength class C35 according to EN 338 by using combined visual and machine strength grading techniques. Three different visual machine strength grading combinations are devised for allocating sawn timber into strength class C35. They are composed on the one hand of the visual gra...
متن کاملAutomated Essay Grading Using Machine Learning
The project aims to build an automated essay scoring system using a data set of ≈13000 essays from kaggle.com. These essays were divided into 8 di erent sets based on context. We extracted features such as total word count per essay, sentence count, number of long words, part of speech counts etc from the training set essays. We used a linear regression model to learn from these features and ge...
متن کاملMachine grading and blemish detection in apples
Five classifiers including the K-means, Fuzzy c-means, K-nearest neighbour, Multi-Layer Perceptron Neural Network and Probabilistic Neural Network classifiers are compared for application to colour grade classification and detection of bruising of Granny Smith apples. A number of suitable discriminate features are determined heuristically for the categorisation of four classes including: high g...
متن کاملA laboratory shaking machine.
Thermoviridin appeared to be an organic acid which was dialyzable. The antibiotic showed maximum absorption in the range of 268 to 272 m,u. Thermoviridin was primarily active against the gram positive bacteria tested. A preliminary toxicity test in mice, consisting of a single intraperitoneal injection of 32 mg of material which had 25 thermoviridin units per mg, did not cause death in any case.
