Machine Learning in Solid‐State Chemistry: Heusler Compounds
Bibliographic record
Abstract
Abstract Machine learning attempts to find underlying trends in data and offer predictions of outcomes. When machine learning is applied to materials science, in a discipline called materials informatics, the complex relationships between composition, structure, and properties can be unraveled even when the quantity of data is limited. To illustrate this application, the large class of materials known as Heusler compounds are modeled through machine learning, enabling new candidates to be predicted or existing compounds to be screened for potentially interesting properties. Data, algorithms, and preprocessing techniques are important components of a successful machine‐learning model. Efforts to predict structures and properties of Heusler compounds are reviewed, and other machine‐learning approaches to discover materials in general are discussed. Ultimately, a machine‐learning model is only valuable if its predictions are validated by experimental results. Thus, perspectives are offered to guide experimentalists on how machine learning can be useful for targeting new Heusler compounds.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
