Fashion-MNIST using Deep Learning with TensorFlow Keras

A few months back, I had presented results of my experiments with Fashion-MNIST using Machine Learning algorithms which you can find in the below mentioned blog:

In the current article, I am presenting the results of my experiments with Fashion-MNIST using Deep Learning (Convolutional Neural Network – CNN) which I have implemented using  TensorFlow Keras APIs (version 2.1.6-tf).

Deploying Machine Learning model in production

In this article, I am going to explain steps to deploy a trained and tested Machine Learning model in production environment.

Though, this article talks about Machine Learning model, the same steps apply to Deep Learning model too.

Below is a typical setup for deployment of a Machine Learning model, details of which we will be discussing in this article.

Process to build and deploy a REST service (for ML model) in production

The complete code for creating a REST service for your Machine Learning model can be found at the below link:

Let us say, you have trained, fine-tuned and tested Machine Learning(ML) model – sgd_clf, which was trained and tested using SGD Classifier on MNIST dataset.  And now you want to deploy it in production, so that consumers of this model could use it. What are different options you have to deploy your ML model in production?

One-on-one discussion on Gradient Descent

Usually, the learners from our classes schedule 1-on-1 discussions with the mentors to clarify their doubts. So, thought of sharing the video of one of these 1-on-1 discussions that one of our CloudxLab learner – Leo – had with Sandeep last week.

Below are the questions from the same discussion.

You can go through the detailed discussion which happened around these questions, in the attached video below.

How To Optimise A Neural Network?

When we are solving an industry problem involving neural networks, very often we end up with bad performance. Here are some suggestions on what should be done in order to improve the performance.

Is your model underfitting or overfitting?

You must break down the input data set into two parts – training and test. The general practice is to have 80% for training and 20% for testing.

You should train your neural network with the training set and test with the testing set. This sounds like common sense but we often skip it.

Compare the performance (MSE in case of regression and accuracy/f1/recall/precision in case of classification) of your model with the training set and with the test set.

If it is performing badly for both test and training it is underfitting and if it is performing great for the training set but not test set, it is overfitting.
