Shisrut S.
Data Scientist
Shisrut ist ein Data Scientist mit sieben Jahren Berufserfahrung, der sich auf maschinelles Lernen, Deep Learning, Zeitreihenprognosen und Optimierungstechniken spezialisiert hat.
Er beherrscht Python, TensorFlow, Scikit-learn und fortgeschrittene ML-Frameworks und integriert nahtlos prädiktive Modellierung in die reale Entscheidungsfindung. Sein Fachwissen liegt in der Kombination von ML-gesteuerten Prognosen mit Optimierungsstrategien zur Maximierung der Geschäftsauswirkungen.
Eine seiner bemerkenswertesten Errungenschaften ist die Optimierung von Homepage-Kachelanordnungen mit einem zweistufigen ML-Framework. Durch den Einsatz von Zeitreihenprognosen und Reinforcement Learning konnte er die Anzahl der Besuche auf der Produktseite und der "In die Tasche"-Aktionen erheblich steigern. Dieses selbstoptimierende System passt sich in Echtzeit an und gewährleistet Skalierbarkeit und langfristigen Erfolg.
