Comparative Analysis of Machine Learning Libraries for Neural Networks: A Benchmarking Study

This comprehensive benchmarking study explores the performance of three prominent machine learning libraries: PyTorch, Keras with TensorFlow backend, and Scikit-learn with the same criteria, software, and hardware. The evaluation encompasses two diverse datasets, "student performance" and "College Attending Plan Classification," supported by Kaggle platforms utilizing feedforward neural networks (FNNs) as the modeling technique. The findings reveal that PyTorch and Keras with TensorFlow backend excel on the "College Attending Plan Classification" dataset, with PyTorch achieving impeccable precision, Recall, and F1-score for both classes. While Scikit-learn demonstrates commendable performance, it trails behind these libraries in this context. On the "Student Performance" dataset, all three libraries deliver comparable results, with Scikit-learn exhibiting the lowest accuracy at 16%. Keras with TensorFlow backend and PyTorch attain accuracy rates of 23%, respectively. Moreover, this study offers valuable insights into each librarys unique strengths and weaknesses when confronted with diverse dataset types. PyTorch emerges as the go-to choice for demanding tasks requiring high performance, while Scikit-learn proves advantageous for simpler tasks with modest computational demands. Keras with TensorFlow backend strikes a balance between performance and user-friendliness. This benchmarking endeavor equips machine learning practitioners with valuable guidance for selecting the most suitable library or framework tailored to their project requirements. It underscores the pivotal role of library choice in achieving optimal results in machine learning endeavors.

Memory retrieval recruits both innate and learned olfactoryprocessing centres in Drosophila

Animals can show either learned or innate behavioral responses to a given stimulus. How these circuits interact to produce an appropriate behavioral response is unknown. In the Drosophila olfactory system, the lateral horn (LH) and the mushroom body (MB) are thought to mediate innate and learned olfactory behavior respectively, although the function of the LH has not been directly tested. Here we identify two LH cell-types (PD2a1/b1) that receive input from an MB output neuron required for recall of aversive olfactory memories. In contrast to the model above we find that PD2a1/b1 are required for aversive memory retrieval. PD2a1/b1 activity is modulated by training, indicating that memory information is passed to the innate olfactory processing centre. We map the connectivity of PD2a1/b1 to other olfactory neurons with connectomic data. This provides a circuit mechanism by which learned and unlearned olfactory information can interact to produce appropriate behavior.
