Learning Objectives for Quarter 4 of 2019
As the final quarter of 2019 has approached us, I’m setting out some personal learning objectives for the next 3 months. This post describes my learning objectives and why I’ve chosen those particular subjects.
Why? Because I like to stay on top of the game with all things computing.
This course shouldn’t be too much of a challenge for me as I already have a background in Python Development, however the ‘programming with Pandas’ part of the course is something I need to focus on as I have no prior experience of using this library.
Applied Data Science with Python Learn how to code in Python for data science, then analyze and visualize data with Python with packages like scikit-learn, matplotlib and bokeh. This is an action-packed learning path for data science enthusiasts and aspiring data scientists who want to learn data science hands-on with Python.
Proficiency in programming in Python for Data Science. Proficiency in analyzing data using pandas. Proficiency in creating different visualizing tools using different Python libraries, namely, Matplotlib, Seaborn, and Folium.
PY0101EN - Python for Data Science
Learning Objectives for this course:
What is Python and why is it useful The application of Python How to define variables Sets and conditional statements in Python The purpose of having functions in Python How to operate on files to read and write data in Python How to use pandas, a must have package for anyone attempting data analysis in Python.
Syllabus for this course:
Module 1 - Python Basics Your first program Types Expressions and Variables String Operations Module 2 - Python Data Structures Lists and Tuples Sets Dictionaries Module 3 - Python Programming Fundamentals Conditions and Branching Loops Functions Objects and Classes Module 4 - Working with Data in Python Reading files with open Writing files with open Loading data with Pandas Working with and Saving data with Pandas
Pandas is a popular library for data analysis. It uses the concepts of dataframes. A dataframe is comprised of rows and columns.
We can use the method head to examine the first 5 rows of a dataframe.
import pandas as pd csv_path = 'file1.csv' df = pd.read_csv(csv_path) df.head() df.ix[0, "Artist"] # Nirvana
Numpy in 1 Dimensional (1D) arrays. Beneficial as this library uses less memory than normal Python. Numpy is a library for scientific computing. See the official docs for more information https://docs.scipy.org/doc/numpy-1.14.0/reference/index.html
Array creating, indexing and slicing,
import numpy as np a=np.array([0,1,2,3,4]) type(a) a.size a.shape a.ndmin # Count of array dimensions Slicing: d=c[1:4] # get first 3 elements x=np.linspace(0, 2*np.pi,100) y=np.sin(x) import matplotlib.pylot as plt %matplotlib inline plt.plot(x,y)
QUESTION 2 of Module 2 - Python Data Structures (1 point possible) After applying the following method,L.append([‘a’,’b’]), the following list will only be one element longer. The available options were True or False. I chose False as I didn’t completely understand the question. Is this a mistake as I don’t see no list?
Final Exam 25 of 25 possible points (25/25) 100%

Deep Learning with TensorFlow (ML0120ENv2)
The majority of data in the world is unlabeled and unstructured. Shallow neural networks cannot easily capture relevant structure in, for instance, images, sound, and textual data. Deep networks are capable of discovering hidden structures within this type of data. In this TensorFlow course you’ll use Google’s library to apply deep learning to different data types in order to solve real world problems.
This Deep Learning with TensorFlow course focuses on TensorFlow. If you are new to the subject of deep learning, consider taking our Deep Learning 101 course first.
Traditional neural networks rely on shallow nets, composed of one input, one hidden layer and one output layer. Deep-learning networks are distinguished from these ordinary neural networks having more hidden layers, or so-called more depth. These kind of nets are capable of discovering hidden structures within unlabeled and unstructured data (i.e. images, sound, and text), which consitutes the vast majority of data in the world.
TensorFlow is one of the best libraries to implement deep learning. TensorFlow is a software library for numerical computation of mathematical expressional, using data flow graphs. Nodes in the graph represent mathematical operations, while the edges represent the multidimensional data arrays (tensors) that flow between them. It was created by Google and tailored for Machine Learning. In fact, it is being widely used to develop solutions with Deep Learning.
In this TensorFlow course, you will be able to learn the basic concepts of TensorFlow, the main functions, operations and the execution pipeline. Starting with a simple “Hello Word” example, throughout the course you will be able to see how TensorFlow can be used in curve fitting, regression, classification and minimization of error functions. This concept is then explored in the Deep Learning world. You will learn how to apply TensorFlow for backpropagation to tune the weights and biases while the Neural Networks are being trained. Finally, the course covers different types of Deep Architectures, such as Convolutional Networks, Recurrent Networks and Autoencoders.
Notice: All the labs in this course are run through CC Labs, however, running deep learning programs usually needs a high performance platform. PowerAI speeds up deep learning and AI using GPU. Built on IBM’s Power Systems, PowerAI is a scalable software platform that accelerates deep learning and AI with blazing performance for individual users or enterprises. The PowerAI platform supports popular machine learning libraries and dependencies including Tensorflow, Caffe, Torch, and Theano. You can download a free version of PowerAI here.
