The Measure and Meaning of Structural Similarity in the Brain
The concept of similarity has recently emerged as a central and often-overlooked organizing principle of brain network structure. At the same time, recent advances in structural MRI analytics have enabled large-scale mapping of anatomical similarity within individual brains. However, key questions …

The Mind as a Predictive Modelling Engine: Generative Models, Structural Similarity, and Mental Representation
… in terms of idealised models that capitalize on structural similarity to their targets; second, an appreciation of prediction as the core function of such models; and third, a regulatory understanding of brain function. I clarify and elaborate on each of these ideas, relate them to contemporary …

Applying case based reasoning and structural similarity for effective retrieval of expert knowledge from software designs
… knowledge from class diagrams using only structural information. The practical applicability of this research has been demonstrated in the areas of cost estimation and plagiarism detection. It was shown that by applying case-based reasoning and graph matching to measure similarity between …

Structure-based realignment of non-coding RNAs in multiple whole genome alignments
… novo prediction of non-coding RNAs (ncRNAs) from structural conservation visible in the alignment. However, current methods for constructing genome alignments do so by explicitly optimizing for sequence similarity but not structural similarity. Therefore, de novo prediction of ncRNAs with high …

Latent diffusion for generative visual attribution in medical image diagnostics
… via the Frechet Inception Distance (FID), Structural Similarity (SSIM) and Multi Scale Structural Similarity Metric (MS-SSIM) metrics obtained between real and generated images. The resulting system also exhibits a range of latent capabilities including super-resolution and zero-shot …

Image Quality Evaluation in Lossy Compressed Images
… were the Modular Image Difference Metric, the Structural Similarity Metric, The Multi-scale Structural Similarity Metric and the Weighted Structural Similarity Metric. The metrics were tested against the subjective results and all were found to have linear correlation in terms of predictability …

Automated Care Pathway Modeling Using Agentic and Knowledge-Aware LLMs
… Automated metrics combine node-level and structural similarity (after Dijkman et al.) with graph-edit distance; a clinician provides fidelity ratings with qualitative annotations. We then investigate knowledge-aware modeling via a categorization of recurrent errors and curated clinical …

The acquisition of French morpho-syntactic properties: Cross-linguistic Influence in the Learning of L3 French by Turkish/Spanish speakers who learned English as an L2
… evidence for CLI based on property-by-property structural similarity. In particular, it is argued that in the absence of clear holistic typological similarity, structural similarity on a property-by-property basis (actual and perceived) is the driving variable for CLI at the initial state of …

Designing quantitative structure activity relationships (QSAR) to predict specific toxic endpoints for polybrominated diphenyl ethers (PBDE) in mammalian cell culture systems.
… materials, and textiles. They are found to be structurally similar to thyroid hormones that are responsible for regulating metabolism in the body. Structural similarity with the hormones poses a threat to human health because once in the system, the PBDEs may change thyroid hormone transport …

Multiple Alignment of Structures using Center of Proteins
There is a buzz among structural biologists about conducting a major portion of their future work in silico, due to progressively refined computational tools and an amazing quantity of digitized biological data. This masters thesis focusses on the area of computational methods for aligning multiple …

Protein Three -Dimensional Structure: Theoretical and Computational Aspects of Structure Prediction Based on the Amino Acid Sequence
… if there is a limited set, even if large, of structural features that describe the protein three-dimensional structure adequately. Towards this end, we created libraries of peptide fragments of sizes 7 to 13 respectively and clustered them based on structural similarity. Analysis of these …

Computational analyses of small molecules activity from phenotypic screens
… These models rely on the principle that two structurally similar compounds are likely to have the same target. In Chapter 3 of this thesis, it was shown that structural similarity and the similarity in phenotypic activity are correlated, and the fraction of phenotypically similar compounds …

Graph similarity and matching
Measures of graph similarity have a broad array of applications, including comparing chemical structures, navigating complex networks like the World Wide Web, and more recently, analyzing different kinds of biological data. This thesis surveys several different notions of similarity, then focuses …
