Error patterns: what do they tell us?
… their analyses. This process of determining an error pattern, in addition, does little in the way of telling a teacher what should be done to help the child. This two-fold problem, extant in all computerized arithmetic diagnostic systems to date, prompted this study which sought other data …

Speech sound acquisition and phonological error patterns in child speakers of Syrian Arabic: a normative study
… for speech sound acquisition and phonological error patterns in the Syrian variety of Arabic is one of the challenging aspects of diagnosing and treating speech disorders in speakers of this language. Although there are normative data which speech language therapists could use to assess the …

Quantifying the Sensitivity of Land-Surface Models to Hydrodynamic Stress Limitations on Transpiration
… should therefore lead to typical intra-daily patterns of error in results of current models.We use a comparison between observational data and model outputs to characterize the patterns of intra-daily error in simulated water flux. Through the use of the North American Carbon Program (NACP) …

Consonant recognition by humans and machines
… Moreover, all the ASR systems produce similar patterns of recognition errors for a given filtering condition. These patterns differ significantly from that characteristic of humans under the same filtering conditions. For syllables degraded by additive speech-shaped noise, none of the automated …

Object-centered representations in echolocating dolphins: evidence from acoustic analyses of object echoes and a human listening study
… representations, an analysis of the dolphin's errors on the matching task was combined with information on the variation in acoustic features between objects. The dolphin's errors could not be fully explained by similarities in single acoustic features, linear combinations of these features, or …

An Experimental Evaluation of Stop-Plosive and Fricative Consonant Intelligibility by Tracheoesophageal Speakers in Quiet and Noise
… to manner and phoneme position. While overall error patterns remained consistent across conditions, voicing distinction was affected differentially according to manner and position. The present investigation provides valuable insight into the difficulties faced by TE speakers in noisy speaking …

Beyond a Relational Understanding of Fractions: Elements of Instruction that Contribute to Preservice Teachers' Knowledge and Motivation
… to use inefficient algorithms did not change. Error patterns at the beginning of the semester revealed misconceptions about fractions, but errors at the end of the semester were largely reflective of low skill. Value and self-concept of ability increased while anxiety decreased, but these …

Coding Techniques for Linear Block Codes With Applications to Fault Identification
… (basis) bits while applying recoding to correct errors among the remaining unreliable redundancy bits. We first determine the optimal ordering of test error patterns when given an information basis, and then characterize the optimality of the so-called most reliable basis. We next develop two …

Benchmarking models of the ventral stream
… behavioral measurements. We collected human error patterns on an object recognition task across a variety of images. By comparing the error pattern of these models to the error pattern of humans, we can measure how similar to the human behavior the model's behavior is. Each model we tested …

Ultra-Wideband Error Modeling for Improved Localization
… develops models to better understand the complex error patterns of UWB range measurements, specifically how separation distance and relative angle between modules affect error. These models are used to develop three error prediction and correction methods to improve localization: (1) range-based …

Inertial Navigation System Drift Reduction Using Scientific Machine Learning
… environments, but they suffer from drift errors that accumulate over time. This thesis introduces Scientific Machine Learning (SciML) as an innovative approach to mitigate INS drift by integrating physical models with machine learning algorithms. The proposed SciML architecture leverages …

Data-Driven Decoding of Quantum Surface Codes using Recurrent Neural Networks
… use of quantum computers is limited by noise and errors in quantum systems. Quantum Error Correction (QEC) provides a way for detecting and correcting these errors, but in the presence of complex and correlated noise, efficient decoding still remains a significant challenge. In this thesis, neural …

Vector quantization applied to speech coding in the wireless environment
… optimal bit allocation scheme, and/or create an error correction scheme, as desired. Using a channel simulation tool such as BERSIM, the user can create bit error patterns to corrupt the data and then decode the speech for playback and analysis. The system is based upon the North American Digital …

The Development of Verbal Morphology in Instructed Italian L2A
… to a series of repeated-measures ANOVAs, and error patterns were analyzed inferentially and descriptively. Results revealed that certain forms (e.g., 1st person singular) of the verbal system are understood and produced with greater speed and accuracy than others (e.g., 2nd and 3rd persons …

A hybrid multilayer error control technique for multihop ATM networks
… links are characterized by higher, time-varying error rates and burstier error patterns in comparison with the fiber-based links from which ATM was designed. The mean time error checking and correction get more and more important and necessary. In this work, a new multilayer error control …

Bit error simulation of FSK, BPSK, and pi/4 DQPSK in flat and frequency-selective fading mobile radio channels using two-ray and measurement- based impulse response models
… The simulation tool generates average bit error rate (BER) and bit-by-bit error patterns with user-specified parameters. The simulation tool can simulate various communication system parameters (i.e. modulation scheme, data rate, signal to noise ratio, and receiver speed, etc.) and …

Implicit learning of distributional patterns in linguistic and non-linguistic sequence production
Speakers implicitly learn phonotactic patterns while speaking syllables. Evidence for this learning appears in speakers’ changing speech error distributions when tasked with rapidly reading sequences of syllables that are generated according to various phonotactic rules (Dell, Reed, Adams, & Meyer, …

Language Comprehension, Production, and Reasoning in Humans and Neural Language Models
… replicating several fine-grained human-like error patterns that are orthogonal to logical accuracy, including premise ordering effects. These converging findings reveal prediction as a fundamental mechanism in comprehension, production, and reasoning in both humans and LMs. While models …
