What is the difference between algorithm and model?
In the context of artificial intelligence and machine learning, particularly as addressed within Google Cloud's machine learning frameworks, the terms "algorithm" and "model" have specific, differentiated meanings and roles. Understanding this distinction is fundamental for grasping how machine learning systems are built, trained, and deployed in real-world applications. Algorithm: The Recipe for Learning An algorithm
What is an optimisation algorithm?
An optimisation algorithm, within the context of machine learning, refers to a systematic mathematical process or procedure used for adjusting the internal parameters of a machine learning model to improve its performance on a specific task. The primary goal of an optimisation algorithm is to find the optimal values of these parameters—commonly known as weights
In the example keras.layer.Dense(128, activation=tf.nn.relu) is it possible that we overfit the model if we use the number 784 (28*28)?
The question concerns the use of the `Dense` layer in a neural network model built using Keras and TensorFlow, specifically relating to the number of units chosen for the layer and its implications on model overfitting, with reference to the input dimensionality of 28×28, which totals 784 features (commonly representing flattened grayscale images from datasets
