Lack of resources in terms of NLP and transformer models **Rating:** 2.0/5.0 stars **Reviewed by:** Takrim A. | Software Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** June 20, 2021 **What do you like best about Theano?** Simple syntax and mainly the applications of CNN models in the domain of deep learning **What do you dislike about Theano?** Lack of online resources mainly in terms of Transformer models and NLP. **Recommendations to others considering Theano:** Try to read documentations as there are not much resources available. **What problems is Theano solving and how is that benefiting you?** Solved problems which are primarily focused on Computer Vision such as using Inception V3 model. ### 2. Lack of resources in terms of NLP and transformer models **Rating:** 2.0/5.0 stars **Reviewed by:** Verified User in E-Learning | Mid-Market (51-1000 emp.) **Reviewed Date:** June 17, 2021 **What do you like best about Theano?** Simple syntax and mainly the applications of CNN models. **What do you dislike about Theano?** Lack of online resources mainly in terms of Transformer models. **Recommendations to others considering Theano:** Try to read documentations as there are not much resources available. **What problems is Theano solving and how is that benefiting you?** Solved problems which are primarily focused on Computer Vision such as using Inception V3 model. ### 3. Theano is stable, optimized and fast in performance. **Rating:** 4.5/5.0 stars **Reviewed by:** Santosh V. | Deep Learning Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 09, 2020 **What do you like best about Theano?** The level of control to write algorithms/networks from scratch is relatively high. It also is faster in executing the networks and comes with an optional keras frontend to make it easier for developer to develop networks. **What do you dislike about Theano?** Without keras as frontend, using raw theano has a high learning curve. **Recommendations to others considering Theano:** Initially, It might be hard to figure out how things work with theano but once picked up, you will find it more stable and optimized. So its worth the initial effort **What problems is Theano solving and how is that benefiting you?** It was harder for me to develop networks from scratch because it has a steeper learning curve. When I figured using it eventually, then I found it more stable and fast compared to other deep learning frame works. ### 4. Brilliant **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Higher Education | Enterprise (> 1000 emp.) **Reviewed Date:** January 25, 2018 **What do you like best about Theano?** Theano is a Python library and is good for making algorithms from scratch. I used standard algorithms and wrote Pylearn2 plugins as Theano expressions, and Theano optimized and stabilize the expressions. It includes all things needed for multilayer perceptron/RBM/Stacked Denoting Autoencoder/ConvNets. **What do you dislike about Theano?** Documentation is a little tough to understand. **What problems is Theano solving and how is that benefiting you?** I was working on the implementation if neural networks on FPGAs using Theano. ## Theano Discussions - [Is theano better than TensorFlow?](https://www.g2.com/discussions/is-theano-better-than-tensorflow) - [Why was theano discontinued?](https://www.g2.com/discussions/why-was-theano-discontinued) - [What programming language did theano use?](https://www.g2.com/discussions/what-programming-language-did-theano-use) - [View Theano pricing details and edition comparison](https://www.g2.com/products/theano/reviews?section=pricing&secure%5Bexpires_at%5D=2026-07-01+01%3A13%3A24+-0500&secure%5Bsession_id%5D=c542910e-61c9-4ade-8b06-42dbcd730581&secure%5Btoken%5D=0b097778c94e7f8f673975b9b5532a40aa62745a98dd12c8cf5723ccb00e5737&format=llm_user) ## Theano Features **Core Functionality - Artificial Neural Network** - Neural Network Training - Neural Network Testing - Model Evaluation - Compliance **Integration - Machine Learning** - Integration **Data Handling - Artificial Neural Network** - Data Integration - Data Preprocessing **Learning - Machine Learning** - Training Data - Actionable Insights - Algorithm **Performance - Artificial Neural Network** - Model Optimization - Scalability **Usability - Artificial Neural Network** - User Interface - Documentation & Support - Customizability **Advanced Features - Artificial Neural Network** - Deep Learning Capabilities - Transfer Learning - Real-Time Processing - Automated Model Tuning - Visualization Tools **Agentic AI - Artificial Neural Network** - Autonomous Task Execution - Multi-step Planning - Cross-system Integration - Adaptive Learning - Natural Language Interaction - Proactive Assistance - Decision Making ## Top Theano Alternatives - [Automation Anywhere Agentic Process Automation](https://www.g2.com/products/automation-anywhere-agentic-process-automation/reviews) - 4.5/5.0 (4,040 reviews) - [Demandbase One](https://www.g2.com/products/demandbase-one/reviews) - 4.4/5.0 (1,941 reviews) - [Phrase](https://www.g2.com/products/phrase-phrase/reviews) - 4.5/5.0 (1,278 reviews)
