bai Modelleri

Model Detayları

bai Modelleri EEG verilerini okumak için eğitilmiştir. Bu modellerin eğitildiği veri setleri Neurazum tarafından gizli tutulmaktadır. Derin öğrenme yöntemleri ile eğitilir ve çok yüksek doğruluk oranları ile EEG üzerinde hassas bir şekilde çalışabilir. Elektrot sayısına bakılmaksızın her türlü EEG cihazı üzerinde çalışabilmektedir (Optimizasyon ve iyileştirmeler devam etmektedir). Nörobilim alanındaki geri kalmışlığa, ilkelliğe ve hata paylarına son vermeyi hedeflemektedir.

Önyargı, Riskler ve Kısıtlamalar

bai Modelleri;

• En büyük riski yanlış tahmin etmesidir :),
• Herhangi bir kısıtlama bulunmamaktadır (şimdilik),
• Beyin sinyallerinden elde edilen veriler kişisel bilgi içermez (çünkü bunlar sadece mV değerleridir). Bu nedenle, bai tarafından yapılan her tahmin sadece bir "TAHMİN" dir.

Öneriler

• Çok fazla duygu durum değişikliği yaşamamaya çalışın,
• Çok fazla farklı nitelikte düşünce/karar almayın,
• Çok fazla hata yaptığında, yanlış cevap verdiğini düşünmeyin (doğru cevap verdiğini farz edin),

Not: Bu öğeler sadece modelin daha iyi çalışması için önerilerdir. Herhangi bir risk taşımazlar.

Modele Nasıl Başlanır

• Modelin içeriğindeki gerekli modülleri kurmak için;

• pip install -r requirements.txt
  

• Örnek kullanımla modelin ve veri setinin yolunu yerleştirin.
• Ve dosyayı çalıştırın.

bai Models

Model Details

bai Models are trained to read EEG data. The data sets on which these models are trained are kept confidential by Neurazum. It is trained with deep learning methods and can work precisely on EEG with very high accuracy rates. It can work on all kinds of EEG devices regardless of the number of electrodes (Optimisation and improvements are ongoing). It aims to end the backwardness, primitiveness and error margins in the field of neuroscience.

Model Description

• Developed by: Neurazum
• Shared by: Eyüp İpler
• Model type: EEG
• License: CC-BY-NC-SA-4.0

Uses

Our aim in these models;

• To analyse the person's emotion instantly,
• To warn dangerous patients such as epilepsy and MS early before the seizure and to take the necessary precautions,
• Early diagnosis for Alzheimer's patients and the bai model helps the person by memorising forgotten words,
• Development of a voice assistant that can be used in everyday life,
• Reducing the margin of error in disease diagnosis thanks to the 12 cranial nerves in the human body.

Bias, Risks, and Limitations

bai Models;

• The biggest risk is wrong prediction :),
• It does not contain any restrictions in any area (for now),
• Data from brain signals do not contain personal information (because they are only mV values). Therefore, every guess made by bai is only a "GUESS".

Recommendations

• Do not experience too many mood changes,
• Do not take thoughts/decisions with too many different qualities,
• When he/she makes a lot of mistakes, do not think that he/she gave the wrong answer (think of it as giving the correct answer),

Note: These items are only recommendations for better operation of the model. They do not carry any risk.

How to Get Started with the Model

• To install the necessary modules in the model;

• pip install -r requirements.txt
  

• Place the path of the model in the example uses.
• And run the file.

Evaluation

• bai-2.0 => (Accuracy very high = %97,93621013133208) (EMOTIONAL CLASSIFICATION)
• bai-2.1 => (Accuracy very high = %97,93621013133208) (EMOTIONAL CLASSIFICATION)
• bai-2.2 => (Accuracy very high = %94,8874296435272) (EMOTIONAL CLASSIFICATION)
• bai-3.0 Emotion => (Accuracy very high = %97,79549718574108) (EMOTIONAL CLASSIFICATION)
• bai-3.0 Epilepsy => (Accuracy high = %68,90829694323143) (SEIZURE DETECTION)
• bai-3.1 Emotion => (Accuracy very high = %95,1219512195122) (EMOTIONAL CLASSIFICATION)

Results

Summary

In summary, bai models continue to be developed to learn about and predict a person's thoughts and emotions.

Hardware

The EEG is the only hardware!

Software

You can then operate this EEG device (for the time being only with audio input) with the real-time data monitoring application we have published.
