The performance of the machine learning model
Machine learning and deep learning are computer science branches that study the design of machines that can learn. Deep learning is a subfield of machine learning that is inspired by artificial neural networks. You can load the data from the box with the library called datasets, which you can download from the server and use to speed up the process.
The train and test images are stored in variables train_X, train_Y, test_X, and test_Y. The training data has a shape of 60000 x 28 x 28 since there are 60,000 training samples each of 28 x 28 dimensions. The test data has a shape of 10000 x 28 x 28 since there are 10,000 testing samples.
That's pretty clear. You can also print a matrix of size 60000 x 10 in which each row depicts one-hot encoding of an image, which you can also print. If you want to use a higher amount of memory, use a higher amount of 64 or 128.
It affects the prediction accuracy by determining the learning parameters. You will train the network for 20 years. Finally!
The model did a good job after 20 epochs, since the training accuracy is 99% and the training loss is low. The model is overfitting as the validation loss is 0.4396 and the accuracy is 92%. The network has a good memory of the training data but it is not guaranteed to work on unseen data, which is why overfitting is important.
Tensor Flow for Handwritten Digit Classification
A tensor is a way of representing the data in deep learning. A tensor can be a single, multiple, or even a trio of variables. A multidimensional array is a tensor.
In machine learning and deep learning, you have high-dimensional datasets that represent different features of the same dataset. Every line of code in TensorFlow has to go through a graph. The first $W$ and $x$ are shown in the figure.
After adding the output of $W$ and $x$ with b, a softmax function is applied, and the final output is generated. Variables allow you to modify the graph to make it work better with the inputs you have. A variable allows you to add parameters to a graph.
The value can be changed throughout the course of time. You can use the MNIST dataset to classify handwritten digits. The image dimensions, training, and test splits are all similar.
You can find the data here. Unlike the other packages, TensorFlow has no preset module to load the Fashion MNIST dataset. To load the data, you need to download the data from the above link and then structure it in a folder format that you can use to work with it.
CNN Classification: A Novel Approach
CNN classification takes any input image and finds a pattern in the image, processes it, and categorizes it into various categories like car, animal, bottle, etc. CNN is used in learning to find similarities in images. The future of technology is being driven by a very complex and interesting algorithm.
The b-matrix
The first three elements of matrix are now used to calculate matrix b. The product is summed to get the result and then stored in a new array.
Modeling in the Wild
A model developer must be smart and know what improvements to make to get a high accuracy model. The training data set can be used for predictions.
Lectures on Deep Learning
There are class notes for each lecture. You can take a practice test to check your understanding. The final practical assignment is to implement your learning.
Deep Learning for Image Processing
Deep Learning has been a very powerful tool because of its ability to handle large amounts of data. The interest in using hidden layers has grown. Convolutional Neural Networks are one of the most popular deep neural networks.
The role of the ConvNet is to reduce the images into a form that is easier to process, without losing features that are critical for getting a good prediction. Neural networks are made of artificial neurons. Artificial neurons are mathematical functions that calculate the weighted sum of multiple inputs and outputs an activation value.
Each layer in a ConvNet creates several functions that are passed on to the next layer. CNNs provide in-depth results despite their power and resources. It is just recognizing patterns and details that are so small that they are noticed by the human eye.
Convolution and non linear functions
The first layer to be used to extract features from an image is convolution. Convolution uses small squares of input data to learn image features. It is a mathematical operation that takes two inputs.
Image classification
The task of image classification is to comprehend an entire image. The goal is to assign the image to a label. Typically, image classification refers to images in which one object is analyzed object detection involves both classification and localization tasks, and is used to analyze more realistic cases in which multiple objects may exist in an image.
Validation and Testing of the X-ray Data
Time to load the validation and test data, do some preprocessing and generation. Preprocessing is necessary to make the image transformation process more efficient and to make the model understand the format.
Cancer Prediction Using CNN
CNN is being used in the medical industry to help doctors get an early prediction about benign or malignant cancer using the tumor images. Look at the X-ray images to get an idea about the disease.
Diving by 9 is important
You may think that diving by 9 is unimportant, but it is more important than you think. Training the network will be useless if the initial values are too small. You can learn more about it by reading.
