Coursera: Machine Learning (Week 4) [Assignment Solution] - Andrew NG Akshay Daga (APDaga) June 08, 2018 Artificial Intelligence, Machine Learning, MATLAB One-vs-all logistic regression and neural … Implement the linear portion of backward propagation for a single layer (layer l), dZ -- Gradient of the cost with respect to the linear output (of current layer l), cache -- tuple of values (A_prev, W, b) coming from the forward propagation in the current layer, dA_prev -- Gradient of the cost with respect to the activation (of the previous layer l-1), same shape as A_prev, dW -- Gradient of the cost with respect to W (current layer l), same shape as W, db -- Gradient of the cost with respect to b (current layer l), same shape as b, ### START CODE HERE ### (≈ 3 lines of code), #print("dA_prev_shape"+str(dA_prev.shape)), [[ 0.51822968 -0.19517421] [-0.40506361 0.15255393] [ 2.37496825 -0.89445391]], # GRADED FUNCTION: linear_activation_backward. hi bro...i was working on the week 4 assignment .i am getting an assertion error on cost_compute function.help me with this..but the same function is working for the l layer modelAssertionError Traceback (most recent call last) in ()----> 1 parameters = two_layer_model(train_x, train_y, layers_dims = (n_x, n_h, n_y), num_iterations = 2500, print_cost= True) in two_layer_model(X, Y, layers_dims, learning_rate, num_iterations, print_cost) 46 # Compute cost 47 ### START CODE HERE ### (≈ 1 line of code)---> 48 cost = compute_cost(A2, Y) 49 ### END CODE HERE ### 50 /home/jovyan/work/Week 4/Deep Neural Network Application: Image Classification/dnn_app_utils_v3.py in compute_cost(AL, Y) 265 266 cost = np.squeeze(cost) # To make sure your cost's shape is what we expect (e.g. I am unable to find any error in its coding as it was straightforward in which I used built in functions of SIGMOID and RELU. Each small helper function you will implement will have detailed instructions that will walk you through the necessary steps. In this notebook, you will implement all the functions required to build a deep neural network. Andrew Ng, the AI Guru, launched new Deep Learning courses on Coursera, the online education website he co-founded.I just finished the first 4-week course of the Deep Learning specialization, and here’s what I learned.. My background. It will help us grade your work. # Implement LINEAR -> SIGMOID. Instructor: Andrew Ng Community: deeplearning.ai Overview. [ 0.37883606 0. ] Now you will implement forward and backward propagation. # Inputs: "A_prev, W, b". In the next assignment, you will use these functions to build a deep neural network for image classification. 2 lines), # Inputs: "grads["dA" + str(l + 1)], current_cache". coursera-Deep-Learning-Specialization / Neural Networks and Deep Learning / Week 4 Programming Assignments / Building+your+Deep+Neural+Network+-+Step+by+Step+week4_1.ipynb Go to file Go to … Deep Learning Specialization Course by Coursera. # Update rule for each parameter. I created this repository post completing the Deep Learning Specialization on coursera… We give you the gradient of the ACTIVATE function (relu_backward/sigmoid_backward). Great! 0. I have recently completed the Machine Learning course from Coursera … # Implement [LINEAR -> RELU]*(L-1). Machine Learning Week 1 Quiz 2 (Linear Regression with One Variable) Stanford Coursera. Building your Deep Neural Network: Step by Step. Look no further. If you find this helpful by any mean like, comment and share the post. Use, Use zero initialization for the biases. In this section you will update the parameters of the model, using gradient descent: Congrats on implementing all the functions required for building a deep neural network!
