CategoricalEncoder.expect_len was never called: assuming category count of 16 to be correct! Sanity check your encoder using `.expect_len`. Ensure that downstream code also uses the correct size. If you are sure this does not apply to you, use `.ignore_len`. 📦 Chunks created: 11 ⏱️ Chunking time: 0.001s 🧠 Prediction time: 23.477s 🔄 Total processing: 23.478s ⚡ Processing rate: 0.5 chunks/sec 📈 Avg confidence: 0.666 🎯 Most common: indian (5 times) 📊 Confidence range: 0.592 - 0.797 🧩 Testing 15-second chunks... 📦 Chunks created: 8 ⏱️ Chunking time: 0.000s 🧠 Prediction time: 25.102s 🔄 Total processing: 25.102s ⚡ Processing rate: 0.3 chunks/sec 📈 Avg confidence: 0.681 🎯 Most common: england (4 times) 📊 Confidence range: 0.602 - 0.849 🧩 Testing 20-second chunks... 📦 Chunks created: 6 ⏱️ Chunking time: 0.000s 🧠 Prediction time: 26.239s 🔄 Total processing: 26.239s ⚡ Processing rate: 0.2 chunks/sec 📈 Avg confidence: 0.671 🎯 Most common: england (4 times) 📊 Confidence range: 0.603 - 0.733 🧩 Testing 30-second chunks... 📦 Chunks created: 4 ⏱️ Chunking time: 0.000s 🧠 Prediction time: 28.015s 🔄 Total processing: 28.015s ⚡ Processing rate: 0.1 chunks/sec 📈 Avg confidence: 0.659 🎯 Most common: england (2 times) 📊 Confidence range: 0.559 - 0.714 🧩 Testing 60-second chunks... 📦 Chunks created: 2 ⏱️ Chunking time: 0.000s 🧠 Prediction time: 25.356s 🔄 Total processing: 25.356s ⚡ Processing rate: 0.1 chunks/sec 📈 Avg confidence: 0.714 🎯 Most common: indian (2 times) 📊 Confidence range: 0.667 - 0.760 ================================================================================ 📈 PERFORMANCE COMPARISON SUMMARY ================================================================================ Size Chunks Total Time Rate Avg Conf Consistency Winner -------------------------------------------------------------------------------- 10 11 23.478 0.5 0.666 0.90 indian 15 8 25.102 0.3 0.681 0.88 england 20 6 26.239 0.2 0.671 0.93 england 30 4 28.015 0.1 0.659 0.89 england 60 2 25.356 0.1 0.714 0.91 indian ============================================================ 🏆 RECOMMENDATIONS ============================================================ ⚡ Fastest processing: 10s chunks (23.48s total) 🎯 Highest accuracy: 60s chunks (0.714 avg confidence) 📊 Most consistent: 20s chunks (0.926 consistency) ⚖️ Best balance: 60s chunks (score: 42.8)
