The environmental impact of machine learning (ML) inference is a growing concern, particularly given the significant compute resources required that contribute to global carbon emissions. While much research has focused on the energy consumption of ML model training, it is the inference phase that consumes the majority of resources, estimated at 70-90% of total compute usage. This discrepancy highlights an opportunity to reduce the environmental footprint by optimizing inference processes. Tools like Seldon Core aim to enhance efficiency through features such as multi-model serving and auto-scaling, which can lower both infrastructure costs and carbon emissions. The importance of technical reports from businesses detailing energy consumption for both training and inference is emphasized, as such data would be invaluable for advancing research and developing strategies to mitigate the environmental impact of ML applications.

Explainable AI (XAI) is emerging as a critical tool in the healthcare industry to address the challenges of trust and compliance in the adoption of machine learning models. The FDA's new guidelines have increased the regulatory scrutiny on AI systems, treating some as medical devices, thereby necessitating transparency in their decision-making processes. XAI provides the means to understand and interpret the reasoning behind AI predictions, which is crucial for ensuring accurate diagnoses, reducing unnecessary procedures, and fostering trust among healthcare providers and patients. Despite being in its early stages, XAI offers significant potential benefits, such as enhanced diagnostic capabilities and ethical decision-making, but faces challenges due to the complexity and sensitivity of medical data. By offering insight into model predictions and enabling real-time error detection, XAI can help mitigate biases and improve the reliability of AI systems, ultimately leading to better patient care and compliance with legal and ethical standards.
