Applied image recognition to health analytics and pitched an app concept with a business plan.</p> <p>&ndash;</p> <p>The &ldquo;AI nutrition grader&rdquo; builds upon &ldquo;Presenting Nutritrack,&rdquo; a project that won my team an <strong>AI app design pitch competition</strong> when we presented a custom CNN <strong>proof-of-concept</strong> and discussed our business plan.</p> <p>The model built for this project, unlike the Nutritrack custom CNN, is a <strong>transfer learning</strong> design. The source for the data is the <em>Nutrition5K</em> dataset (<strong>RGB images of food</strong> on white plates). This model includes an <strong>augmentation layer</strong> to increase the size of the dataset, by changing the angles of the plates to create a greater volume of training data.</p> <p>For transfer learning, the AI nutrition grader CNN model uses a <em>MobileNetV2</em> backbone pretrained on <em>ImageNet</em>. The model builds a <strong>custom classification head for feature extraction</strong> and then <strong>fine-tunes the deeper layers</strong> to adapt to its own food image dataset (drawn from <em>Nutrition5K</em>).</p> <p>The README for this project on GitHub provides access to the images selected for this project&rsquo;s dataset, with details about how to <strong>download large image files</strong> so others can clone this repository and <strong>replicate</strong> the AI nutrition grader project without needing to download the full <em>Nutrition5K</em> dataset.</p> https://gfriedman77.github.io/project/research/ Wed, 10 Sep 2025 00:00:00 +0000 https://gfriedman77.github.io/project/research/ <p>Analyzed 780+ graded mathematical proofs to compare LLM vs. human grader consistency and accuracy. Identified feedback errors and applied statistical testing to evaluate grading reliability.</p> <!--for the future when have a link to the article: [📄](/uploads/proofs_poster.pdf)--> https://gfriedman77.github.io/project/time-series/ Mon, 16 Dec 2024 00:00:00 +0000 https://gfriedman77.github.io/project/time-series/ <p>Conducted time-series analysis of rates of employment type by sex and province.
