Unsupervised learning in second-order neural networks for motion analysis
No full textThis paper demonstrates how unsupervised learning based on Hebb-like mechanisms is sufficient for training second-order neural networks to perform different types of motion analysis. The paper studies the convergence properties of the network in several conditions, including different levels of noise and motion coherence and different network configurations. We demonstrate the effectiveness of a novel variability dependent learning mechanism, which allows the network to learn under conditions of large feature similarity thresholds, which is crucial for noise robustness. The paper demonstrates the particular relevance of second-order neural networks and therefore correlation based approaches as contributing mechanisms for directional selectivity in the retina
Lexical and Discoursal Nativisation in Baba Malay: Portraying Ethnic Identity in Malaysian Fiction
No full textThis study investigates the nativisation of Baba Malay in Malaysian English literature, focusing on how its lexical and discoursal elements shape the ethnic identity in selected short stories. The primary objective is to examine how the Straits Chinese author Lee Su Kim integrates Baba Malay into English narratives to reflect cultural hybridity. Using a qualitative approach, the study applies Kachru’s (1986) framework to analyse nativisation strategies, categorised into contextual, cohesive, and rhetorical adaptations. A selection of 19 short stories from Kebaya Tales and Sarong Secrets was made based on their incorporation of Baba Malay expressions, cultural themes, and linguistic adaptation. The analysis was validated through an expert informant review to ensure linguistic and cultural accuracy. The findings reveal that Lee Su Kim strategically employs Baba Malay lexical borrowings, hybridised expressions, and culturally embedded discourse styles to construct a distinct Peranakan identity. This study contributes to discussions of language adaptation, ethnic representation, and bilingual creativity in postcolonial literature, reinforcing the role of nativised English in preserving cultural narratives.
