How you can Construct a Mannequin to Predict Inventory Costs utilizing ChatGPT
On this part, we are going to take a look at a primary instance of constructing an information science mission on constructing a mannequin to foretell inventory costs utilizing ChatGPT. We’ll comply with all of the steps talked about above.
Downside Assertion
Develop a machine studying mannequin to predict future stock prices primarily based on historic knowledge, utilizing shifting averages as options. Consider the mannequin’s accuracy utilizing Imply Squared Error and visualize predicted vs. precise costs.
Information Assortment
Immediate
Load the dataset and crucial libraries to foretell future inventory costs primarily based on historic knowledge. Additionally Outline the ticker image, and the beginning and finish dates for fetching historic inventory value knowledge
Code generated by ChatGPT
import yfinance as yf
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
from sklearn.model_selection import train_test_split, GridSearchCV
from sklearn.linear_model import LinearRegression
from sklearn.metrics import mean_squared_error, mean_absolute_error, r2_score
ticker_symbol="AAPL"
start_date="2021-01-01"
end_date="2022-01-01"
stock_data = yf.obtain(ticker_symbol, begin=start_date, finish=end_date)
stock_data
Output
Information Preprocessing and Exploration
Immediate
Now examine for lacking values and discover the construction of the fetched inventory value dataset. Summarize any findings relating to lacking knowledge and supply insights into the dataset’s traits and construction.
Code Generated by ChatGPT
missing_values = stock_data.isnull().sum()
print("Lacking Values:n", missing_values)
Output
Information Visualization
Immediate
Now visualize historic inventory value knowledge to determine tendencies and patterns. Create a plot showcasing the closing value of the inventory over time, permitting for insights into its historic efficiency.
Code Generated by ChatGPT
print("Dataset Info:n", stock_data.information())
Output
Now Visualize the historic inventory value knowledge.
plt.determine(figsize=(10, 6))
plt.plot(stock_data['Close'], coloration="blue")
plt.title(f"{ticker_symbol} Inventory Value (Jan 2021 - Jan 2022)")
plt.xlabel("Date")
plt.ylabel("Shut Value")
plt.grid(True)
plt.present()
Output
Characteristic Engineering
Immediate
Subsequent step is to generate shifting averages (MA) of the closing value, reminiscent of MA_50 and MA_200, to function options for the predictive mannequin. Tackle lacking values arising from the rolling window calculations to make sure the integrity of the dataset.
Code Generated by ChatGPT
stock_data['MA_50'] = stock_data['Close'].rolling(window=50).imply()
stock_data['MA_200'] = stock_data['Close'].rolling(window=200).imply()
print(stock_data['MA_50'])
print(stock_data['MA_200'])
Output
Take away rows with lacking values on account of rolling window calculations.
stock_data.dropna(inplace=True)
Outline options (shifting averages) and goal (shut value).
X = stock_data[['MA_50', 'MA_200']]
y = stock_data['Close']
print(X.head())
print(y.head())
Output
Break up the info into coaching and testing units.
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
print(X_train.head())
print(X_test.head())
print(y_train.head())
print(y_test.head())
Output
Mannequin Improvement
Immediate
Optimize the linear regression mannequin by hyperparameter tuning utilizing GridSearchCV. Initialize and prepare the linear regression mannequin with the optimum parameters recognized from the hyperparameter tuning course of.
parameters = {'fit_intercept': [True, False]}
regressor = LinearRegression()
grid_search = GridSearchCV(regressor, parameters)
grid_search.match(X_train, y_train)
best_params = grid_search.best_params_
print("Greatest Parameters:", best_params)
Output
Initialize and prepare the linear regression mannequin with finest parameters.
mannequin = LinearRegression(**best_params)
mannequin.match(X_train, y_train)
Output
Mannequin Analysis
Immediate
Make the most of the educated mannequin to make predictions on the take a look at knowledge. Calculate analysis metrics together with Imply Squared Error (MSE), Imply Absolute Error (MAE), Root Imply Squared Error (RMSE), and R-squared (R^2) rating to evaluate mannequin efficiency. Visualize the expected versus precise shut costs to additional consider the mannequin’s effectiveness.
Code Generated by ChatGPT
predictions = mannequin.predict(X_test)
# Calculate analysis metrics
mse = mean_squared_error(y_test, predictions)
mae = mean_absolute_error(y_test, predictions)
rmse = np.sqrt(mse)
r2 = r2_score(y_test, predictions)
print("Imply Squared Error:", mse)
print("Imply Absolute Error:", mae)
print("Root Imply Squared Error:", rmse)
print("R^2 Rating:", r2)
Output
Visualize the expected vs. precise shut costs.
plt.scatter(y_test, predictions, coloration="blue")
plt.title("Precise vs. Predicted Shut Costs")
plt.xlabel("Precise Shut Value")
plt.ylabel("Predicted Shut Value")
plt.grid(True)
plt.present()
