You work on an artificial intelligence team at ABC Neural Inc. Your client, the New York City Transit Authority, provides an hourly feed of subway ridership data (entries and exits) for the NYC Subway system. Your task is to predict the number of riders each hour for each subway station.

Design and outline a solution (both functional and non-functional requirements) that takes the hourly ridership data as input and delivers predictions of hourly ridership back to the client. Predictions must be consistently updated as new data arrives, and the end product will be integrated into the client’s internal systems.

Identify requirements for a machine learning model that predicts subway transit

Subway Machine Learning Model

Suppose there exists a new airline named Jetco that flies domestically across North America. Jetco recently had a study commissioned that tested the boarding time of every airline, and it came out that Jetco had the fastest average boarding times of any airline.

What factors could have biased this result, and what would you look into?

What could potentially bias the average boarding time in favor of an airline that only flies domestically?

What could potentially bias the average boarding time in favor of an airline that only flies domestically?

Boarding Times Bias

A new airline came out as the fastest average boarding times compared to other airlines.  What factors could have biased this result and what would you look into?

Given an array of integers, write a function <code>min_distance</code> to calculate the minimum absolute distance between two elements then return all pairs having that absolute difference.

Note: Make sure to return the pairs in ascending order.

Example:

Input:

<pre tabindex="0" class="chroma"><code>v = [3, 12, 126, 44, 52, 57, 144, 61, 68, 72, 122]
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>def min_distance(V) -&gt;

min = 4

[[57, 61], [68, 72], [122, 126]]
</code></pre>
