AI and Forests- What an Odd Match!
The efficient use of technology in forestry is a new topic for environmental programs, but replanting is not. Many companies have decided to refocus their industry on what we now refer to as Climate Tech, which essentially means increasing productivity in any soil reforestation research, measurement, and analysis process.
Gradually Climate tech gave birth to Nature tech. Nature tech, in its broadest definition, is high-tech applications that enable, accelerate, and scale-up NbS (as in Nature-based Solutions), according to NatureforClimate.org, and includes the following areas:
- LiDAR technology for reforestation is one example of technology to deploy NbS.
- Satellite monitoring and DNA testing are examples of technology to monitor, verify, and report on NbS.
- Improved openness about NbS thanks to technology
- NbS uses technology to connect people and conservation efforts.
- In a nutshell, nature technology attempts to maintain, sustainably manage, and restore ecosystem functions while also benefiting human health and biodiversity.
So, this was Climate tech and Nature tech. Now, we will discuss random forests.
What is a random forest?
A random forest is a supervised machine learning system that uses decision tree algorithms to build it. This algorithm is used to anticipate behavior and outcomes in multiple industries, including banking and eCommerce.
A random forest is a machine learning technique for solving classification and regression problems. It makes use of ensemble learning. And that is a technique that solves complex problems by combining several classifiers.
Many decision trees make up a random forest algorithm. Bagging or bootstrap aggregation are used to train the forest formed by the random forest method. Bagging is a meta-algorithm that increases the accuracy of machine learning methods by grouping them.
Random forest definition
The random forest algorithm determines the outcome based on decision tree predictions. It forecasts by averaging the output of various trees. The precision of the result improves as the number of trees grows.
A random forest method overcomes the drawbacks of a decision tree algorithm. It reduces dataset overfitting and improves precision. And it also generates forecasts without requiring a large number of package setups (like sci-kit-learn).
Random forest algorithm characteristics
- It outperforms the decision tree algorithm in terms of accuracy.
- It is an effective tool for dealing with missing data.
- Without hyper-parameter adjustment, it can provide a reasonable prediction.
- It overcomes the problem of decision tree overfitting.
- At the node’s splitting point in every random forest tree, a subset of features gets selected.
How random forest algorithm works
A random forest algorithm’s building components are decision trees. As we know, a decision tree is a decision-making tool with a tree-like structure. A basic understanding of decision trees will aid our understanding of random forest algorithms.
There are three parts to a decision tree: decision nodes, leaf nodes, and root nodes. A decision tree method separates a training dataset into branches. This pattern repeats until a leaf node is reached. There is no way to separate the leaf node any further.
The attributes utilized to forecast the outcome gets represented by the nodes in the decision tree. The leaves get connected to the decision nodes. The three types of nodes in a decision tree are depicted in the diagram below.
Nature also needs technological assistance
Nature-tech can assess, track, and help ecosystems thrive by combining several technological technologies. Let us take a closer look.
- A tree absorbs between 10 and 30 kg of CO2 per year on average, so 22 trees are needed to meet the oxygen needs of just one person every day.
- Because trees are an essential source for lowering and balancing the emissions created by their deforestation, the use of nature tech can aid forests in CO2 reduction and compensation.
- Returning the true value of trees should be a primary component of any environmental policy aimed at solving the current environmental issues. As a result, nature tech and NbS are critical to today’s environmental activities.
Addressing the environmental crisis
Concerns about carbon emissions and potential actions on the horizon for businesses and governments have risen dramatically in recent months. The triple environmental crises have resurfaced as a topic of discussion among international leaders.
Organic meals, sustainable apparel, and zero-waste technology are examples of eco-friendly alternatives to our daily living choices. These remedies are beneficial, but they are insufficient to address environmental challenges.
We are not completely aware of how technology can help in preserving, restoring, and regenerating nature. Why? Because these are the planet’s most important assets.
Applications of random forests
You can use random forests for a variety of purposes, including:
Banking
In banking, a random forest is used to estimate a loan applicant’s creditworthiness. It assists the loan-providing organization in making an informed decision about whether or not to grant the loan to the consumer. The random forest technique is often used by banks to detect fraudsters.
Health-care services
Random forest algorithms are also utilized by doctors to diagnose patients. Patients are diagnosed by looking at their past medical records. Previous medical data are examined to determine the proper dosage for the patients.
The stock exchange
The Random Forest algorithm is used by financial experts to discover potential stock markets. It also enables them to recognize stock behavior.
eCommerce
eCommerce merchants can forecast customer preferences based on prior consumption behavior using rain forest algorithms.
When should you not use random forests?
In terms of data extrapolation, random forest regression is not ideal. Unlike linear regression (which uses existing observations to estimate values outside of the observation range), nonlinear regression uses pre-existing observations to estimate values outside of the observation range. Now that explains why the majority of random forest applications are related to classification.
Wrapping Up
So now you know the definition and role of random forest algorithm, climate tech, and nature tech. We have also discussed the rain forest algorithm, which is easy to use and flexible. The rain forest algorithm is ideal for developers because it solves the problem of overfitting datasets. It is indeed a useful tool for making accurate predictions that are needed in strategic decision-making in organizations.
