I really liked how systematically Andrew Ng goes through this broad field. Question 10 You decide to use data augmentation to address foggy images. Finding good hyperparameter values is very time-consuming. While doing the course we have to go through various quiz and assignments. Take your time to complete this assignment and make sure you get the expected outputs when working through the different exercises. True because it is greater than the other error categories added together 8.
The assignments blend well with the lectures and there is a lot of code that's already included so you would have to work your way out with the rest. We will cover both image and video recognition, including image classification and annotation, object recognition and image search, various object detection techniques, motion estimation, object tracking in video, human action recognition, and finally image stylization, editing and new image generation. Which curve corresponds to which algorithm? The number of hidden layers is 4. Which of these do you think is the best choice? Do I like to learn from theoretical texts? The individual courses are free to Audit, but you need to visit the course pages separately. Donations to freeCodeCamp go toward our education initiatives, and help pay for servers, services, and staff. The second part then covers elementary deep learning concepts through the TensorFlow library.
After you are done, submit your work and check your results. The book starts with a discussion on machine learning basics, including the applied mathematics needed to effectively study deep learning linear algebra, probability and information theory, etc. True False 1 point 5. The Deep Learning Specialization The consists of five different courses. This may be resolved by updating to the latest version.
Why is the best mini-batch size usually not 1 and not m, but instead something in-between? Deep Learning is one of the most highly sought after skills in tech. In other words, most of the difficulty in implementing neural nets--such as the logic and structure of the code and aligning matrix dimensions--is taken care of for you so you don't need to be a strong programmer to complete the assignments. True False 1 point 6. Ask your team to take into account both accuracy and false negative rate during development. Deep Learning Lecture Nando de Freitas is a machine learning professor at the University of British Columbia. However, no assignment will be accepted more than three days after its due date, and late days cannot be used for the final project and final presentation.
Andrew Ng is no longer at Coursera full time, but acts as the co-chairman of the board. This is the second course of the Deep Learning Specialization. Late assignments Each student will have a total of ten free late calendar days to use for programming assignments, quizzes, project proposal and project milestone. The first excellent course of Andrew Ng's specialization on deep learning. Jurgen Schmidhuber, , arXiv, 2014. You can access all of the assignments as a freeware student, so even though the course won't be listed as completed when you finish, you can still work through them and learn all the same things as paying students. Deep learning programming frameworks require cloud-based machines to run.
Having built a good Bird detector, you should be able to take the same model and hyperparameters and just apply it to the Cat dataset, so there is no need to iterate. You therefore have to set α to be very small to prevent divergence; this will slow down learning. This is the third course in the Deep Learning Specialization. You will have to watch around 10 videos more or less 10min each every week. We also have thousands of freeCodeCamp study groups around the world.
You have a large data-mismatch problem because your model does a lot better on the training-dev set than on the dev set You have a large variance problem because your training error is quite higher than the human-level error. In order to make the hardcopies feasible, I need to provide a ton of added value through the virtual machine and video tutorials. Between these two, Approach B is more of an end-to-end approach because it has distinct steps for the input end and the output end. The number of layers L is 4. It is used to cache the intermediate values of the cost function during training.
Rather than the deep learning process being a black box, you will understand what drives performance, and be able to more systematically get good results. Check all that apply Try better random initialization for the weights Try tuning the learning rate α Try mini-batch gradient descent Try using Adam Try initializing all the weights to zero 1 point 10. For example, if a group submitted their project proposal 23 hours after the deadline, this results in 1 late day being used per student. How many layers does this network have? Unless the student has a temporary disability, Accommodation letters are issued for the entire academic year. You need to instead use np.
Programming assignment Optimization2h Programming Assignment: Optimization30 min Master the process of hyperparameter tuning Hyperparameter tuning Tuning process7 min Using an appropriate scale to pick hyperparameters8 min Hyperparameters tuning in practice: Pandas vs. Finding the characteristics of a model is key to have good performance. Add regularization Get more training data Increase the number of units in each hidden layer Get more test data Make the Neural Network deeper 1 point 4. One iteration of mini-batch gradient descent computing on a single mini-batch is faster than one iteration of batch gradient descent. Decreasing β will create more oscillation within the red line.
