<h3 id="distances-and-similarity">Distances and Similarity<a class="headerlink" href="#distances-and-similarity" title="Permanent link">&para;</a></h3>
<p>Chroma uses distance metrics to measure how dissimilar a result is from a query. A distance of 0 indicates that the two items are identical, while larger distances indicate greater dissimilarity. This approach starts at 0 and increases upward, aligning with the intuitive notion of distance.</p>
<p>In contrast, similarity metrics measure how similar two items are, often on a scale where higher values represent greater similarity. For example:</p>
<div class="language-text highlight"><pre><span></span><code>• Cosine Similarity ranges from -1 to 1, where:
• 1 indicates identical orientation (maximum similarity),
• 0 indicates orthogonality (no similarity),
• -1 indicates opposite orientation (maximum dissimilarity).
• Dot Product can range from negative to positive infinity, depending on the vectors’ magnitudes and directions. When vectors are normalized and non-negative, the dot product ranges from 0 to 1.
</code></pre></div>
<ul>
<li>Cosine Similarity ranges from -1 to 1, where:</li>
<li>1 indicates identical orientation (maximum similarity),</li>
<li>0 indicates orthogonality (no similarity),</li>
<li>-1 indicates opposite orientation (maximum dissimilarity).</li>
<li>Dot Product can range from negative to positive infinity, depending on the vectors' magnitudes and directions. When vectors are normalized and non-negative, the dot product ranges from 0 to 1.</li>
</ul>
<h4 id="why-does-chroma-use-distance-metrics">Why Does Chroma Use Distance Metrics?<a class="headerlink" href="#why-does-chroma-use-distance-metrics" title="Permanent link">&para;</a></h4>
<p>Chroma uses distance metrics because they provide a straightforward way to quantify dissimilarity between vectors. Consistency is another key aspect - irrespecitve of the distance metric used, distance results follow the same conceptual framework. Finally, distance is is an intuitive metric which makes Chroma more accessible to a wider audience.</p>
