How do you create a deep learning classifier?

The steps to build a CNN classifier are as follows.

1. Collect and preprocess your data set.
2. Select an appropriate CNN base model.
3. Fine-tune the model.
4. Evaluate your fine-tuned model’s accuracy.
5. Prepare your final model for inference and save it.

How do I create CNN image classification from scratch?

The basic steps to build an image classification model using a neural network are:

1. Flatten the input image dimensions to 1D (width pixels x height pixels)
2. Normalize the image pixel values (divide by 255)
3. One-Hot Encode the categorical column.
4. Build a model architecture (Sequential) with Dense layers.

How much data does it take to train a neural network?

According to Yaser S. Abu-Mostafa(Professor of Electrical Engineering and Computer Science) to get a proper result you must have data for at-least 10 times the degree of freedom. example for a neural network which has 3 weights you should have 30 data points.

How to improve the performance of an image classification model?

Your image classification model has a far better chance of performing well if you have a good amount of images in the training set. Also, the shape of the data varies according to the architecture/framework that we use. Hence, the critical data pre-processing step (the eternally important step in any project).

Is your classifier firing on all cylinders?

If your training data is reliable, then your classifier will be firing on all cylinders. So let’s dig into the best practices you can adopt to create a powerful dataset for your deep learning model. The label structure you choose for your training dataset is like the skeletal system of your classifier.

Can you identify the car model in a given image?

Recently, our partner Data Insights received a challenging request from a major car company: Develop a Computer Vision application which could identify the car model in a given image.

How many images do I need to classify each class?

A rule of thumb on our platform is to have a minimum number of 100 images per each class you want to detect. In many cases, however, more data per class is required to achieve high-performing systems. If you seek to classify a higher number of labels, then you must adjust your image dataset accordingly.
