Sign in. In data science projects, custom science project, we use similar steps depending on the nature of the problem. Usually, a da t a science project consists of problem identification, data collection and preparation, feature engineering, training and testing model, and deployment. In these steps, several functions are used. A data scientist needs to use those functions over custom science project over again in different projects.
For example, a data scientist imports custom science project models to train and then fits the model with training data and then predicts based on the fitted model.
Therefore, if the codes used repeatedly can be saved somewhere and reused all custom science project time, it will save a lot of time and make the code much cleaner than last time.
This is where building custom packages can custom science project a data scientist create reusable codes. Package and Module:. Package in python is a collection of modules.
On the other hand, The python module is a file that consists of python statements and definitions. Python has its own packages which we import and use all the time in our code. Similarly, we can create our own modules and save them as a package so that we can use them over and over again by importing them into our code.
This can help to manage codes better and to increase the reusability of the codes. This post will show how we can create a custom package that consists of one module and use it in our regression problem. Building our custom package:.
In this problem, we will use xgboost and random forest regression models to train the model for demonstration purposes. We will then evaluate the model accuracy using mean absolute percentage error MAPE. Finally, we will try to optimize the accuracy using grid search for both the model.
Therefore, we will create all those functions to train and evaluate models as well as to optimize the hyper-parameters of the models. We will put all those functions in a python file which will be our module and then we will create a package by inserting that module. We can keep adding modules in that package going forward.
From the above code, we can see that we imported all the necessary libraries and then created 4 functions, custom science project. We can use any name we want. So, this is very important. This is all we need. Now, we want to put the folder in our python directory so that every time we need it, we can import it as a built-in python package.
I am using anaconda3, custom science project. So, I will go to that folder and then find my site packages for anaconda distribution inside the lib folder as shown below.
After that, I called the help function to see what we have inside the module. We can see that it is showing all the four function that is saved inside module file. It also shows the path where we have that module on our computer. Now, we can use these functions in our problem again and again instead of writing exclusively or copy-pasting.
Zoo management is trying to understand the number of llamas that will be available in different habitats. The projection will help them to plan for the foods so that they can feed the llamas properly.
We have 20 months of custom science project data on the number of llamas in different habitats and also some weather features. The data files can be found in the following link. Data Preprocessing:. In this step, we just import the data and do some preprocessing to prepare the data for our machine learning model. Model Building:.
Now, we split the data into train and test. In the second section, we fitted both the random forest and xgboost regression models with our training data. There is no need to create the regression object and then fit them with training data. The imported function will do this job. Model Evaluation:. We just pass the model and the test values for both x and y.
We can see the MAPE for the random forest is Hyper-parameter Optimization:. In this section, we will use the optimization function from our module to tune hyperparameters for both models. In the above block, we first created two-parameter grids. Finally, we call our optimization function which mainly calculates the best values for the hyperparameters of the models and fits the refined models.
Again, we are able to avoid writing long code for the hyperparameter tuning functions. We just used the function from our module, custom science project.
Below custom science project the results of the tuned model. From the above example, we can see that how easily we can create our own python data science packages and use them in our projects repeatedly. This process will also help to keep your code clean and save a lot of time, custom science project. It is very important to place the custom package inside the site package of the python directory so that we can use our custom package just like the built-in packages in python, custom science project.
