To build a recommendation system for a streaming platform, I would adopt a hybrid approach combining collaborative filtering and content-based filtering. Collaborative filtering leverages user behavior, such as ratings and viewing history, to identify patterns and suggest content that similar users enjoyed. Content-based filtering analyzes the attributes of the content (genres, actors, directors) to recommend similar items based on what a user has previously liked.
First, I would gather data on user interactions, including viewing history, ratings, and demographic information. I would preprocess this data to handle missing values and normalize features. Next, I would implement matrix factorization techniques (like Singular Value Decomposition) for collaborative filtering and build a profile for each item using content features for content-based recommendations.
For evaluation, I would use metrics such as Mean Absolute Error (MAE) for prediction accuracy and Precision/Recall at k to assess the relevance of recommended items. Additionally, I would consider the Normalized Discounted Cumulative Gain (NDCG) to evaluate ranking quality. A/B testing with real users could provide further insights into the system’s effectiveness in driving engagement and satisfaction.

To identify the top-selling product categories, I would start by analyzing the dataset in a systematic manner.
Data Preparation
First, I would clean the dataset to ensure it’s accurate and consistent. This includes handling missing values, removing duplicates, and converting data into the correct format, like ensuring dates are in a recognizable format.
Segmenting Data by Season
Next, I would categorize the purchase dates into seasons (e.g., Spring, Summer, Fall, Winter) based on their timestamps. This allows me to segment the data so that I can analyze sales patterns within each season.
Analyzing Product Categories
I would then aggregate the data by summing up the sales (in terms of quantity and revenue) for each product category within each season. This will help identify the top-selling categories during different times of the year.
Understanding Influencing Factors
To understand the factors influencing these patterns, I would analyze the demographic data, such as age, gender, and location, to see how these factors correlate with the seasonal purchase trends. For instance, younger customers might prefer different categories in the summer compared to older customers.
Visualization Techniques
Using data visualization tools, like bar charts or pie charts, I would visualize the trends, making it easier to spot patterns and anomalies. For example, I might find that certain products sell better in winter due to holiday season demand.
Finally, I would summarize the findings, highlighting the top-selling categories for each season and the demographic factors that most influence these sales. This insight could then inform marketing strategies, inventory management, and targeted promotions to maximize sales in future seasons.
