What do image classification models predict?
Given sufficient training data (often hundreds or thousands of images per label), an image classification model can learn to predict whether new images belong to any of the classes it has been trained on.
This process of prediction is called inference..

What are Pretrained models?
Simply put, a pre-trained model is a model created by some one else to solve a similar problem. Instead of building a model from scratch to solve a similar problem, you use the model trained on other problem as a starting point. For example, if you want to build a self learning car.
Which algorithm is best for multiclass classification?
We use many algorithms such as Naïve Bayes, Decision trees, SVM, Random forest classifier, KNN, and logistic regression for classification.

Which neural network is best for image classification?
Convolutional Neural NetworksConvolutional Neural Networks (CNNs) is the most popular neural network model being used for image classification problem. The big idea behind CNNs is that a local understanding of an image is good enough.

What are the different types of classification?
Broadly speaking, there are four types of classification. They are: (i) Geographical classification, (ii) Chronological classification, (iii) Qualitative classification, and (iv) Quantitative classification.
Why CNN is best for image classification?
CNNs are used for image classification and recognition because of its high accuracy. … The CNN follows a hierarchical model which works on building a network, like a funnel, and finally gives out a fully-connected layer where all the neurons are connected to each other and the output is processed.
