Abstract

fetched live from OpenAlex

In order to solve the problems of low categorization accuracy and uneven distribution of the traditional forestry information text classification algorithm,a forestry information text classification algorithm based on Gaussian mixture model(GMM) was puts forward. On the basis of Gaussian mixture model(GMM) and the principle of parametric estimation algorithm,the formula of TFIDF was used to compute text eigenvalue,the constructed feature matrix of forestry information text was reduced in the dimension of eigenmatrix. The Kmeans algorithm should be used,then get the parameters of Gaussian mixture model(GMM) through training of forestry information text,lastly a classifier of Gaussian mixture model(GMM) was established to achieve the goal of faster and accurate classification of forestry information text. The experimental results show that the algorithm has higher accuracy and practicality than the algorithm of neural network and Bayesian and decision tree,and the algorithm pioneer new ideas for studying the forestry information text classification algorithm.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
