✅ Cross Validation & Hyperparameter Tuning 🤖⚙️ 👉 Building a model is not enough. We must also make sure it performs well on unseen data. This is done using: ✔ Cross Validation ✔ Hyperparameter Tuning 🔹 1. What is Cross Validation? Cross Validation checks how well a model generalizes to new data. 👉 Instead of using only one train-test split, data is divided multiple times. 🔥 2. K-Fold Cross Validation ⭐ How it Works: 1️⃣ Split data into K parts (folds) 2️⃣ Use one fold for testing 3️⃣ Use remaining folds for training 4️⃣ Repeat until every fold is tested ✅ Example If K = 5: - 4 folds → Training - 1 fold → Testing Repeated 5 times. 🔹 3. Why Cross Validation is Important? ✔ Better model evaluation ✔ Reduces overfitting risk ✔ More reliable accuracy 🔹 4. Implementation (Python) from sklearn.model_selection import cross_val_score from sklearn.linear_model import LogisticRegression model = LogisticRegression() scores = cross_val_score(model, X, y, cv=5) print(scores) 🔥 5. What are Hyperparameters? 👉 Hyperparameters are settings controlled before training the model. Examples: ✔ Number of trees in Random Forest ✔ Value of K in KNN ✔ Learning rate 🔹 6. Hyperparameter Tuning 👉 Finding the best settings for the model. 🔥 7. Grid Search ⭐ Grid Search tries multiple parameter combinations automatically. from sklearn.model_selection import GridSearchCV ✅ Example params = { "n_neighbors": [3,5,7] } 👉 Tests different K values in KNN. 🔹 8. Why Tuning is Important? ✔ Improves model performance ✔ Increases accuracy ✔ Helps build optimized ML systems 🎯 Today’s Goal ✔ Understand cross validation ✔ Learn K-Fold method ✔ Understand hyperparameters ✔ Learn Grid Search basics 💬 Tap ❤️ for more!

santai aja, ini cuma dunia.

🌳 Kalian suka dipanggil dengan panggilan apa guys :3

gilaaa, 15 ribu likes 😭😭. aku aman kok, gak ditambahin kerjaan tapi disuruh ngajarin pivot aja hari ini 🙏. kalo di excel, ALT adalah kunci. Tinggal pencet ALT, nanti ada begini begini tapi gak langsung jago ya, harus banyak banyak pake excel 😭🙏

"kerjaan mah banyak, lu aja yg milih milih" God FORBID someone dont want to work 12+ hours without any hari libur with low salaries and want to pursue karir yg mereka mau 😃

knp ya.... Di tengah sulitnya ekonomi dan lowongan kerja tuh banyak yg gampang resign dalam waktu seminggu... Adekku pun jg gitu I mean, kerja seenak apa sih yg kalian cari... tempat kerjanya harus sempurna dalam segala aspek dulu kah, ga butuh uang kah.. at least 6 bulan gitu

20 juta di kantor kamu gaji level jabatan apa?

kalo kalian ortunya white collar, coba bandingin deh jaman mereka kerja dan naik corpo ladder kok dapet benefit macem2 banget, full time juga common ga kontrak 5 taun dulu. ada yg dpt benefit asuransi swasta se keluarga, kacamata gue aja dulu ke-cover..sekarang gue aja bpjs doang
