Abstract

fetched live from OpenAlex

In this paper, we try to identify a set of reduced features capable of distinguishing between two classes by performing double clustering using fuzzy c-means. We decided on using fuzzy c-means because a fuzzy model fits better the gene expression data analysis. Fuzziness parameter m is a major problem in applying fuzzy c- means method for clustering. In this approach, we applied fuzzy c-means clustering using different fuzziness parameters for two forms of microarray data. Support vector machine with different kernel functions are used for classification. As a result of the experiments conducted on the colon dataset, we have observed that CSVM is able to correctly classify the whole training and test sets when the data is log2 transformed and when in is close to 1.5.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
