Erdos story - Voice activated Operational safety for Astronauts - for Chauncey Robinson

Background

We have been working with the early foundation members of Erdos Research

The basic idea of Erdos is

1) As a non-developer/ domain expert - you come up with an AI problem statement in an area you like

2) We develop it jointly at Erdos using low code (LLM assisted) approach

3) You work with us in the community / mentored manner to develop this idea using our methodology and tools

4) We develop using the MIT license - so if you want to develop it as a venture - you are free to do so beyond the learning

5) Erdos is thus a great and unique way to learn AI

I already shared Antonella Gasco 's story and approach for AI in asset management

Chauncey H. Robinson came up with an unusual problem statement:

Voice activated Operational safety for Astronauts?

This was inspired by the Space station in his native Alabama in USA?

So, I proposed to work with Chancey to?

1) Refine the problem

2) choose a quantifiable problem - which can be modelled as a machine learning problem

3)? Relate to a real life scenario

We chose to model the problem of operational safety for astronauts based on the use of death valley for testing the mars rover??

The overall steps are??

• Choose Persona
• Articulate Problem in terms of persona
• Break down problem into subproblems?
• Breakdown into Concepts that you need
• Ask which Algorithms you could use
• Choose one
• Generate Synthetic data
• Generate code
• Iterate and refine
• Create product backlog?

Below I outline our approach. This is still work in progress. It's an unusual problem statement but it's a great way to learn AI based on a problem you are passionate about.

If you want to be learn AI as a non-developer, please message me here

Approach

• In this case, the persona is the astronaut.?
• We start with understanding how to predict weather of extreme locations (such as death valley)
• Then find what it compares to (Mars)
• We then identify extreme scenarios for training (for mas in death valley)
• Then we choose temperature drops and their prediction
• Then we identify a sample dataset for this
• Followed by python code?
• And an example of classifier (random forest)

• label: A binary indicator (1 or 0), where 1 indicates a significant temperature drop within the next 3 hours.

How can you predict the weather of extreme environments on earth such as the death valley

Predicting the weather in extreme environments like Death Valley requires specialized approaches due to the unique and often harsh conditions. Here are the key factors and methods used to forecast weather in such areas:

1. Understanding the Geographic and Climatic Features

2. Satellite Data

3. Automated Weather Stations

4. Numerical Weather Prediction (NWP) Models

5. Historical Weather Data

6. Expert Analysis

7. Use of Specialized Equipment

8. Predictive Analytics and Machine Learning.

To what planet is the climate of death valley comparable to

The climate of Death Valley, known for its extreme heat and dryness, is often compared to conditions on Mars, particularly due to several key similarities:

1. Extreme Temperature Fluctuations

2. Arid Environment

3. Soil and Surface Conditions

4. Atmospheric Conditions

5. Pressure Conditions

6. Sunlight and UV Radiation

If you wanted to train astronauts about martian conditions in death valley - what aspects could you train them on

for the predict_temperature_drops create a sample dataset

Conceptual Dataset Structure

To effectively simulate the dataset needed for predicting temperature drops using satellite infrared data, consider the following components:

1. Calibrated Radiance (Infrared Data): This is the primary input, which would be a matrix of infrared radiance values from satellite observations.
2. Temperature Data: Derived from the calibrated radiance using the conversion formulas or lookup tables.
3. Cloud Mask: A binary matrix indicating cloud presence, which affects temperature readings.
4. Temperature Gradients: Numerical gradients of temperature to help identify potential fronts.
5. Time-Series Data: Historical temperature data at specific locations to capture trends.
6. Front Indicators (Labels): Whether a sudden temperature drop is observed (or predicted) after the current data point.

Example Synthetic Dataset

Here's a simplified example where we create synthetic data to illustrate the concept. This dataset will include temperature data, temperature gradients, and a binary label indicating whether a temperature drop occurred.

• Temperature Data: Simulated based on typical daily temperature patterns and random fluctuations.
• Temperature Gradients: Computed as the difference between successive temperature values.
• Labels (Front Indicators): 1 if a temperature drop is detected; otherwise, 0.

Python Implementation

Explanation of the Code

1. Time Index: Creates a time series to simulate hourly data across several days.
2. Baseline Temperature: Models a sinusoidal daily temperature pattern plus random noise to simulate typical temperature variations.
3. Cold Front Simulation: Introduces a sharp temperature drop over a short period to mimic a cold front.
4. Temperature Gradient: Computes the gradient to detect significant changes in temperature, which helps identify potential fronts.
5. Labels: Marks data points that precede a significant temperature drop within the next 3 hours as 1, otherwise 0.

Show the dataset for this problem

Key Points of the Dataset

• time: The timestamp of the measurement.
• temperature: The simulated temperature at that time, adjusted to show a pattern similar to natural conditions with added noise and a sudden drop to simulate a cold front.
• temperature_gradient: The rate of change of temperature, which helps identify rapid changes.
• label: A binary indicator (1 or 0), where 1 indicates a significant temperature drop within the next 3 hours.

Which machine learning algorithm could you use in this case

To predict temperature drops using the dataset we've constructed, several machine learning algorithms can be effectively applied. The choice of algorithm depends on the characteristics of the data and the specific requirements of the prediction task, such as the need for interpretability, computational efficiency, and prediction accuracy.

Here’s an overview of suitable machine learning algorithms for this task and why they might be appropriate:

1. Random Forest Classifier

2. Gradient Boosting Machines (GBM)

3. Support Vector Machines (SVM)

4. Logistic Regression

5. Neural Networks (Deep Learning)

6. K-Nearest Neighbors (KNN)
