Downloading Dataset¶
Installing aicrowd-cli
!pip install aicrowd-cli
%load_ext aicrowd.magic
%aicrowd login
!rm -rf data
!mkdir data
%aicrowd ds dl -c bhpob -o data
Importing Libraries¶
In this baseline, we will be using skleanr library to train the model and generate the predictions
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
from sklearn.neighbors import KNeighborsClassifier
from sklearn.preprocessing import normalize
import os
import matplotlib.pyplot as plt
import seaborn as sns
from IPython.display import display
Reading the dataset¶
Here, we will read the train.csv which contains both training samples & labels, and test.csv which contains testing samples.
# Reading the CSV
train_data_df = pd.read_csv("data/train.csv")
test_data_df = pd.read_csv("data/test.csv")
# train_data.shape, test_data.shape
display(train_data_df.head())
display(test_data_df.head())
Data Preprocessing¶
# Separating data from the dataframe for final training
X = normalize(train_data_df.drop(columns=["22"]).to_numpy())
y = train_data_df["22"].to_numpy()
print(X.shape, y.shape)
# Visualising the final lable classes for training
sns.countplot(y)
Splitting the data¶
# Splitting the training set, and training & validation
X_train, X_val, y_train, y_val = train_test_split(X, y, test_size=0.2)
print(X_train.shape)
print(y_train.shape)
X_train[0], y_train[0]
Training the Model¶
model = KNeighborsClassifier()
model.fit(X_train, y_train)
Validation¶
model.score(X_val, y_val)
So, we are done with the baseline let's test with real testing data and see how we submit it to challange.
Predictions¶
# Separating data from the dataframe for final testing
X_test = normalize(test_data_df.to_numpy())
print(X_test.shape)
# Predicting the labels
predictions = model.predict(X_test)
predictions.shape
# Converting the predictions array into pandas dataset
submission = pd.DataFrame({"node":predictions})
submission
# Saving the pandas dataframe
!rm -rf assets
!mkdir assets
submission.to_csv(os.path.join("assets", "submission.csv"), index=False)
Submitting our Predictions¶
Note : Please save the notebook before submitting it (Ctrl + S)
!!aicrowd submission create -c bhpob -f assets/submission.csv
