SetFit with BAAI/bge-small-en-v1.5

This is a SetFit model that can be used for Text Classification. This SetFit model uses BAAI/bge-small-en-v1.5 as the Sentence Transformer embedding model. A LogisticRegression instance is used for classification.

The model has been trained using an efficient few-shot learning technique that involves:

Fine-tuning a Sentence Transformer with contrastive learning.
Training a classification head with features from the fine-tuned Sentence Transformer.

Model Labels

Label	Examples
Power Subsystem	'The electrical generation capability of a satellite is primarily determined by the efficiency and surface area of its photovoltaic cells, which convert incident solar radiation into electrical energy.' 'Energy distribution within the satellite is managed by a network of bus bars and wiring harnesses, designed to minimize resistive losses and maintain voltage stability across all operational conditions.' 'Redundant power paths and autonomous fault detection mechanisms are implemented to ensure continuous electrical supply even in the event of subsystem failures or external anomalies.'
Thermal Control	'Discuss the significance of thermal isolation techniques in preventing heat transfer between satellite components.' 'The thermal emissivity of radiators and heat pipes is optimized to dissipate the excess heat generated by power electronics, maintaining thermal equilibrium within the satellite.' 'Deployable radiators can be utilized to increase the heat rejection capacity of a satellite, particularly during high-power operational phases.'
Propulsion	'The combustion efficiency of a rocket engine depends on factors like propellant mixture ratio, injector design, and combustion chamber pressure.' 'Liquid rocket engines utilize cryogenic fuels and oxidizers, such as liquid hydrogen and liquid oxygen, which require complex storage and handling systems to maintain their extremely low temperatures.' 'The nozzle design, including its shape and expansion ratio, significantly influences the exhaust velocity and overall thrust of a rocket engine.'
