In a regression problem, we aim to predict the output of a continuous value, like a price or a probability. We created deep neural net for regression and finally accurately able to predict stock price. It can be written in a general form as Y=G(X) and for the purpose of this demonstration, let us consider the linear version where Y=GX. Import TensorFlow import tensorflow as tf from tensorflow.keras import datasets, layers, models import matplotlib.pyplot as plt Because this tutorial uses the Keras Sequential API, creating and training our model will take just a few lines of code. First, using selective search, it identifies a manageable number of bounding-box object region candidates (“region of interest” or “RoI”).And then it extracts CNN features from each region independently for classification. The classes are mutually exclusive and there is no overlap between them. ... (CNN) contains one or more convolutional layers, in which inputs are neighborhoods of pixels, resulting in a network that is not fully-connected, but is suited to identifying spatial patterns. This type of architecture is dominant to recognize objects from a picture or video. CIFAR has 10 output classes, so you use a final Dense layer with 10 outputs. The full code is available on Github. In practical applications, the knowledge to be transferred may represent complex physical equations with varying initial/boundary conditions.

You can try the classification-then-regression, using the G-CNN for the classification part, or you may experiment with the pure regression approach. Tensorflow has an official Object Detection API. I used 2 sets of square brackets because the tf.matmul function needs a matrix and the (X,Y) in the for loop are scalars. We also may not have sufficient test or validation data. I quote from here, This is a big oversimplification, but there are essentially two types of machine learning libraries available today, Deep learning (CNN,RNN, fully connected nets, linear models) and Everything else (SVM, GBMs, Random Forests, Naive Bayes, K-NN, etc).
