<h2>Conclusions and Insights</h2>
|
|
<p>Through in-depth analysis of the MovieLens dataset, we found significant correlations between user characteristics (gender, age, occupation) and movie preferences. Key findings include:</p>
|
|
<ul>
|
|
<li>Significant differences in movie genre preferences between genders</li>
|
|
<li>Age influences how users rate movies from different decades</li>
|
|
<li>Occupational background correlates with genre preferences</li>
|
|
</ul>
|
|
<p>These findings provide valuable reference for designing movie recommendation systems and developing movie marketing strategies.</p>
