In this course, you'll work on an industry-level machine learning project based on predicting weekly retail sales given different factors. You will learn the most efficient techniques used to train and evaluate scalable machine learning models. After completing this course, you will be able to take on industry-level machine learning projects, from data analysis to creating efficient models and providing results and insights.

The code for this course is built around the TensorFlow framework, which is one of the premier frameworks for industry machine learning, and the Python pandas library for data analysis. Basic knowledge of Python and TensorFlow are prerequisites. To get some experience with TensorFlow, try our course: Machine Learning for Software Engineers.

This course was created by AdaptiLab, a company specializing in evaluating, sourcing, and upskilling enterprise machine learning talent. It is built in collaboration with industry machine learning experts from Google, Microsoft, Amazon, and Apple.

Applied Machine Learning: Industry Case Study with TensorFlow

# Chapter Goals:
- Set up the regression function's training code

# A. The <code>EstimatorSpec</code>

There are three phases to completing the machine learning model: training, evaluation, and prediction. With TensorFlow, we can easily bundle the three phases into a single function using [`EstimatorSpec`](https://www.tensorflow.org/api_docs/python/tf/estimator/EstimatorSpec) objects for each phase.

The `EstimatorSpec` object has three modes corresponding to the three phases:
- Training: `tf.estimator.ModeKeys.TRAIN`

- Evaluation: `tf.estimator.ModeKeys.EVAL`
- Prediction: `tf.estimator.ModeKeys.PREDICT`

The `EstimatorSpec` is initialized with whatever mode corresponds to the current phase of completing the machine learning model. For training, the `EstimatorSpec` is also initialized with the model's loss and training operation (for minimizing the loss).
