import pandas as pd
from sklearn.neighbors import NearestNeighbors

# Load data
data = pd.read_csv("customer_purchases.csv")
# Preprocess data and create a customer-product matrix
customer_product_matrix = data.pivot(index="customer_id", columns="product_id", values="purchase_count")
customer_product_matrix.fillna(0, inplace=True)

# Fit the model
model = NearestNeighbors(metric="cosine", algorithm="brute")
model.fit(customer_product_matrix)

# Get recommendations
distances, indices = model.kneighbors(customer_product_matrix, n_neighbors=5)
recommendations = [list(customer_product_matrix.index[indices[i]]) for i in range(len(indices))]

# Return the recommendations
recommendations
'
WITH RESULT SETS ((Recommendations NVARCHAR(MAX)))
  • Dynamic Pricing Model:
EXEC sp_execute_external_script
  @language = N'R',
  @script = N'
library(randomForest)
