fix: correct typo from "Convolution Neural Networks" to "Convolutiona…

…l Neural Networks"

The term "Convolution Neural Networks" was misspelled. It has been corrected to "Convolutional Neural Networks" to ensure accuracy and consistency in terminology. This change affects the introductory section of the Image Classification documentation.

 # Image Classification
 
-Image classification is the task of categorizing an image into one of several predefined classes, often also giving a probability of the input belonging to a certain class. This task is crucial in understanding and analyzing images, and it comes quite effortlessly to human beings with our complex visual systems. Most powerful image classification models today are built using some form of Convolution Neural Networks (CNNs), which are also the backbone of many other tasks in Computer Vision.

 ## Where to get started?
 In this Collection, you will find state-of-the-art implementations of Image Classification models and their containers. A good place to get started with Image Classification is with the [ResNet-50](https://github.com/NVIDIA/DeepLearningExamples/tree/master/PyTorch/Classification/ConvNets/resnet50v1.5) model.
 
-ResNets (Residual Networks) are very popular Convolutional Neural Network architectures built with blocks utilizing skip connections to jump over some layers. As the name suggests, ResNet-50 is a variant that is 50 layers deep! But why do we need these “skip” connections? As it turns out building better CNN architectures is not as simple as stacking more and more layers. In practice, If we just keep adding depth to a CNN, at some point the performance stagnates or may start getting worse. Very deep networks are notoriously difficult to train, because of the vanishing gradient problem. In simpler terms, as the depth increases, repeated multiplications during back-propagation may end up making the gradient vanishingly small. This may prevent weights from changing. In ResNets, the skip connects are meant to act like a “gradient superhighway” allowing the gradient to flow unrestrained thus alleviating the problem of the vanishing gradients. ResNets were very influential in the development of subsequent Convolutional Network architectures, and there is much more to them than the brief summary above!
