📢Day 10/100: Class Imbalance Challenges Class imbalance is a persistent issue in fraud detection and credit scoring. 🚨
In my dataset:
Fraudulent transactions are rare (<5%), making prediction tricky. Techniques like SMOTE (Synthetic Minority Oversampling Technique) helped balance the dataset. 💡 Key Insight: Balancing the data improved model precision for rare classes like fraud detection.
💡 Question: What other methods do you use to address class imbalance without oversampling?

Again, in contrast to Facebook, Google and Twitter, Telegram's founder Pavel Durov runs his company in relative secrecy from Dubai. And while money initially moved into stocks in the morning, capital moved out of safe-haven assets. The price of the 10-year Treasury note fell Friday, sending its yield up to 2% from a March closing low of 1.73%. "Someone posing as a Ukrainian citizen just joins the chat and starts spreading misinformation, or gathers data, like the location of shelters," Tsekhanovska said, noting how false messages have urged Ukrainians to turn off their phones at a specific time of night, citing cybersafety. He said that since his platform does not have the capacity to check all channels, it may restrict some in Russia and Ukraine "for the duration of the conflict," but then reversed course hours later after many users complained that Telegram was an important source of information. Official government accounts have also spread fake fact checks. An official Twitter account for the Russia diplomatic mission in Geneva shared a fake debunking video claiming without evidence that "Western and Ukrainian media are creating thousands of fake news on Russia every day." The video, which has amassed almost 30,000 views, offered a "how-to" spot misinformation.
