DS Stream has successfully centralized operations on GCP for FMCG clients, utilizing MLOps to enhance cost-efficiency and streamline development processes. This approach has proven effective in reducing operational expenditures and improving application quality and reliability.

Start Small

Pilot Project Selection

Starting with a pilot project helps demonstrate the value of MLOps and gain stakeholder buy-in. Choose a project with a clear, achievable objective and measurable outcomes. Examples include:

Inventory Optimization: Use machine learning to predict inventory needs and reduce overstock and stockouts.

Example Implementation:

import pandas as pd

import tensorflow as tf

from tensorflow.keras.models import Sequential

from tensorflow.keras.layers import Dense, LSTM, Dropout

from sklearn.preprocessing import MinMaxScaler

import matplotlib.pyplot as plt

# Generate synthetic inventory data

def generate_inventory_data():

    time = pd.date_range(start='1/1/2020', periods=1000)

    demand = pd.Series(data=(20 + 0.5 * time.dayofyear + (np.random.randn(len(time)) * 5)), index=time)

    return demand

demand = generate_inventory_data()

# Prepare the data

scaler = MinMaxScaler(feature_range=(0, 1))

demand_scaled = scaler.fit_transform(demand.values.reshape(-1, 1))

def create_sequences(data, seq_length):

    X, y = [], []

    for i in range(len(data) - seq_length):

        X.append(data[i:i + seq_length])

        y.append(data[i + seq_length])

    return np.array(X), np.array(y)

seq_length = 30

X, y = create_sequences(demand_scaled, seq_length)

# Reshape data for LSTM [samples, time steps, features]

X = X.reshape((X.shape[0], X.shape[1], 1))

# Define the LSTM model

model = Sequential([

    LSTM(128, return_sequences=True, input_shape=(seq_length, 1)),

    Dropout(0.2),

    LSTM(64),

    Dropout(0.2),

    Dense(1)

])

model.compile(optimizer='adam', loss='mse')

# Train the model

history = model.fit(X, y, epochs=50, batch_size=32, validation_split=0.2)

# Save the model

model.save('inventory_optimization_model_v2.h5')

# Plot training & validation loss values

plt.plot(history.history['loss'])

plt.plot(history.history['val_loss'])

plt.title('Model loss')

plt.ylabel('Loss')

plt.xlabel('Epoch')

plt.legend(['Train', 'Validation'], loc='upper right')

plt.show()

Demand Forecasting: Implement models to forecast product demand based on historical data and market trends.

Example Implementation:

import pandas as pd

import numpy as np

import tensorflow as tf

from tensorflow.keras.models import Sequential

from tensorflow.keras.layers import Dense, Conv1D, Flatten, Dropout

from sklearn.model_selection import train_test_split

from sklearn.preprocessing import StandardScaler

# Load historical sales data

data = pd.read_csv('historical_sales_data.csv')

# Feature engineering

data['date'] = pd.to_datetime(data['date'])

data['month'] = data['date'].dt.month

data['day_of_week'] = data['date'].dt.dayofweek

data['year'] = data['date'].dt.year

# Assuming 'sales' is the target and 'promotion' is a binary feature

features = ['month', 'day_of_week', 'promotion', 'year']

X = data[features]

y = data['sales'].values

# Standardize the features

scaler = StandardScaler()

X_scaled = scaler.fit_transform(X)

# Train/test split

X_train, X_test, y_train, y_test = train_test_split(X_scaled, y, test_size=0.2, random_state=42)

# Reshape for Conv1D [samples, time steps, features]

X_train = X_train.reshape((X_train.shape[0], X_train.shape[1], 1))

X_test = X_test.reshape((X_test.shape[0], X_test.shape[1], 1))

# Define the model

model = Sequential([

    Conv1D(64, kernel_size=2, activation='relu', input_shape=(X_train.shape[1], 1)),

    Dropout(0.3),

    Conv1D(32, kernel_size=2, activation='relu'),

    Flatten(),

    Dense(50, activation='relu'),

    Dense(1)

])

model.compile(optimizer='adam', loss='mse', metrics=[tf.keras.metrics.RootMeanSquaredError()])

# Train the model

history = model.fit(X_train, y_train, epochs=50, batch_size=32, validation_data=(X_test, y_test))

# Save the model

model.save('demand_forecasting_model_v2.h5')

# Evaluate the model

loss, rmse = model.evaluate(X_test, y_test)

print(f'Test RMSE: {rmse}')

# Plot training & validation loss values

plt.plot(history.history['loss'])

plt.plot(history.history['val_loss'])

plt.title('Model loss')

plt.ylabel('Loss')

plt.xlabel('Epoch')

plt.legend(['Train', 'Validation'], loc='upper right')

plt.show()

DS Stream executed a project for an FMCG client that involved migrating multiple use cases to a centralized GCP platform, resulting in cost savings and streamlined operations. This was achieved through the strategic use of Docker, Kubernetes, and CI/CD pipelines.

Leveraging AI Models for Automation

Enhancing Data Quality Assurance

AI models can automate data validation and cleaning processes, ensuring data accuracy and completeness. OpenAI’s models can be used to identify anomalies, fill missing values, and correct data types.

Example: Data Validation with OpenAI’s GPT-4o

import openai

# Set up OpenAI API key

openai.api_key = 'your-api-key'

# Function to validate data using GPT-4o

def validate_data(data):

    prompt = f"Check the following data for anomalies, missing values, and ensure correct data types: {data}"

    response = openai.ChatCompletion.create(

        model="gpt-4o",

        messages=[

            {"role": "system", "content": "You are a data validation assistant."},

            {"role": "user", "content": prompt}

        ],

        max_tokens=150

    )

    return response['choices'][0]['message']['content'].strip()

# Example data to be validated

data = {

    "age": [25, 30, None, 45, 50],

    "income": [50000, 60000, 70000, None, 90000]

}

# Validate data

validation_result = validate_data(data)

print(validation_result)

Building Scalable Data Pipelines

AI models can assist in designing scalable data pipelines by providing recommendations on tools and practices for data ingestion, processing, and storage. OpenAI can generate code snippets and configurations for tools like Apache Kafka and Apache Spark.

Example: Designing a Data Pipeline with OpenAI’s GPT-4o

# Function to generate a data pipeline design using GPT-4o

def generate_pipeline_design(requirements):

    prompt = f"Design a scalable data pipeline based on the following requirements: {requirements}"

    response = openai.ChatCompletion.create(

        model="gpt-4o",

        messages=[

            {"role": "system", "content": "You are an expert in data engineering."},

            {"role": "user", "content": prompt}

        ],

        max_tokens=300

    )

    return response['choices'][0]['message']['content'].strip()

# Example requirements for the pipeline

requirements = """

The pipeline should handle real-time data ingestion from multiple sources, process the data using Apache Spark, and store the processed data in a data warehouse. It should also include fault tolerance and be easily scalable.

“””

# Generate pipeline design

pipeline_design = generate_pipeline_design(requirements)

print(pipeline_design)

Implementing Version Control

AI models can help manage version control for data and models by generating scripts to track changes, ensuring reproducibility and collaboration.

Example: Managing Data Versions with OpenAI’s GPT-4o

# Function to generate version control scripts for data using GPT-4o

def generate_version_control_script(data_description):

    prompt = f"Generate a version control script for the following data: {data_description}"     response = openai.ChatCompletion.create(         model="gpt-4o",         messages=[             {"role": "system", "content": "You are a software engineer specializing in data management."},             {"role": "user", "content": prompt}         ],         max_tokens=200     )     return response['choices'][0]['message']['content'].strip() # Example data description data_description = """ Data contains columns: date (date), sales (float). The script should track changes, save versions to a remote repository, and handle merging conflicts.

"""

# Generate version control script

version_control_script = generate_version_control_script(data_description)

print(version_control_script)
