DoorDash’s prediction service, Sibyl, was created to handle real-time predictions in their machine learning infrastructure. Sibyl retrieves both models and features from independent stores to make predictions. The prediction service allows batch and shadow predictions to test multiple models on the same data in the background. Sibyl was built to […]

Rectified Linear Unit (ReLU) is a commonly used activation function in artificial neural networks. An activation function is a mathematical function that is applied to the output of a neuron in a neural network to determine whether the neuron should be activated or not. ReLU is defined as follows: f(x) […]

Python ile veri bilimi ve makine öğrenmesi konusunda çalışmak istiyorsak işe NumPy ve Pandas ile başlamamız gerekiyor. Çok basit bir örnek uygulama ile başlayabiliriz. Bir giriş veri setimiz var, bir işlemden geçerek bir sonuç seti oluşuyor. Bunun algoritmasını tahmin etmeye çalışıyoruz. Sigmoid fonksiyonu ile iterasyonu ayarlıyoruz. Bu temel bir yaklaşımdır.
