1KOMMA5° wurde gegründet um Millionen Gebäude in Europa klimaneutral immer mit dem günstigsten Strom zu versorgen - ganz ohne fossile Energie. Mit „Heartbeat AI“ betreibt 1KOMMA5° Europas größtes dezentrales Kraftwerk. Heartbeat AI steuert Elektroautos, Batterien, Wärmepumpen oder Klimaanlagen und handelt sie in Echtzeit an der Strombörse. Das System kauft Strom wenn er besonders günstig ist und verkauft Strom wenn er teuer ist. In Summe profitieren Nutzer von nahezu kostenlosem Strom. Das Konzept gilt als günstigere Alternative zu fossilen, zentralen Kraftwerken und könnte laut einer Roland-Berger-Studie aus dem Jahr 2025 bis zu 255 Milliarden Euro an Stromkosten einsparen. Inzwischen steuert „Heartbeat AI“ rund 50.000 Energiesysteme mit einer Leistung von 600 Megawatt, was etwa der Leistung eines modernen Gaskraftwerks entspricht. 1KOMMA5° ist aktuell in sieben Ländern aktiv und betreibt 80 Standorte, um Installation und Service als "One Stop Shop" für Kunden regional und in höchster Qualität sicherzustellen.

Better datasets create better machine learning models, enabling better products.Quality Match verifies and improves the quality of datasets for computer vision and machine learning. This can be applied to: - dataset architecture (are my dataset and taxonomy good?) - measure the quality of annotation providers (is the quality as advertised?) - evaluate model performance (when does the model fail?) - supervise model-drift (is the model still working?) and many more use cases. We focus on creating actionable, quantitative metrics on dataset quality, such as: - representativeness (bias analysis) - accuracy (labels, detection rates and geometric properties of annotations) - and ambiguity (edge cases due to bad data or bad taxonomies). We do this by breaking down quality questions into a large decision tree where each node is either a training-free, unambiguous crowd-sourcing task which is repeated until statistical significance, or a pretrained machine learning model with known confusion matrix. We call this system our Annotation Quality Engine. To verify your data, we help you verifying and integrating your metrics into our Annotation Quality Engine which you will then be able to query through a simple REST API.
