प्रकाश आकर्षण: कई कीट (जैसे पतंगे) प्राकृतिक रूप से प्रकाश की ओर आकर्षित होते हैं। इसे “फोटोटैक्सिस” कहते हैं। कीटों को लगता है कि प्रकाश का स्रोत चाँद या सूरज है, जिससे वे अपनी दिशा का निर्धारण करते हैं।
गर्मी: गर्मियों में तापमान अधिक होने के कारण कीड़े अधिक सक्रिय हो जाते हैं। लाइट या आग से निकलने वाली गर्मी भी उन्हें आकर्षित करती है।
शिकार और भोजन: लाइट के आस-पास छोटे कीट और मच्छर भी आकर्षित होते हैं, जो बड़े कीटों के लिए शिकार का काम करते हैं। इसलिए, कीड़े लाइट या आग के पास आते हैं ताकि वे अपने शिकार को पकड़ सकें।
प्रजनन और संचार: कुछ कीट प्रकाश का उपयोग संचार और प्रजनन के लिए करते हैं। वे अपने साथियों को आकर्षित करने के लिए प्रकाश के पास आते हैं।
इन कारणों से, बारिश के दिनों में आग और रोशनी पर कीड़े का आना एक सामान्य घटना है।
और भी कई बातें हैं जिनकी वजह बारिश के दिनों में आग और रोशनी पर कीड़े अधिक आते हैं:
प्राकृतिक प्रवृत्ति: कीड़ों की प्राकृतिक प्रवृत्ति होती है कि वे रात में दिशा का निर्धारण करने के लिए चंद्रमा के प्रकाश का उपयोग करें। जब वे मानव निर्मित प्रकाश स्रोतों को देखते हैं, तो वे भ्रमित हो जाते हैं और उसकी ओर आकर्षित हो जाते हैं।
लाइट स्पेक्ट्रम: विभिन्न प्रकार के प्रकाश स्रोत (जैसे बल्ब, एलईडी लाइट्स) विभिन्न प्रकार के स्पेक्ट्रम का प्रकाश उत्सर्जित करते हैं। कुछ कीड़े खासकर उन तरंग दैर्घ्य (wavelengths) के प्रति संवेदनशील होते हैं जो लाइट स्रोतों से निकलती हैं।
अवरोधक तंत्र: लाइट या आग के पास आते हुए कीड़े अक्सर अपने प्राकृतिक शिकारी तंत्र से विचलित हो जाते हैं, जिससे उनकी दिशा भटक जाती है और वे लाइट या आग के पास आ जाते हैं।
आद्रता: गर्मियों में नमी का स्तर भी अधिक होता है। कई कीड़े नमी से भी आकर्षित होते हैं क्योंकि यह उनके शरीर के लिए आवश्यक होता है। आग के आसपास नमी की अधिकता होती है, जिससे वे वहां आते हैं।
स्वास्थ्य और पर्यावरण: गर्मियों में वातावरण में अधिक कीड़े होते हैं, जो स्वाभाविक रूप से लाइट या आग की ओर आकर्षित होते हैं। यह पर्यावरणीय बदलाव और प्रजनन चक्र का हिस्सा होता है।
रसायन और फेरोमोन: कुछ कीड़े विशेष प्रकार के रसायनों और फेरोमोन की ओर आकर्षित होते हैं जो प्रकाश स्रोतों के पास अधिक मात्रा में हो सकते हैं।
पर्यावरणीय परिवर्तन: गर्मियों में पेड़-पौधों की वृद्धि अधिक होती है, जिससे कीड़ों के लिए भोजन और प्रजनन के अवसर बढ़ जाते हैं। लाइट या आग के पास ये कीड़े भोजन की तलाश में आ सकते हैं।
शारीरिक प्रतिक्रिया: कई कीड़ों की आंखें बहुत संवेदनशील होती हैं और वे प्रकाश की ओर तेजी से प्रतिक्रिया करते हैं। यह एक त्वरित स्वाभाविक प्रतिक्रिया होती है जिसे वे नियंत्रित नहीं कर सकते।
शिकारी से बचाव: कुछ कीड़े प्रकाश स्रोतों के पास आते हैं क्योंकि वहां अन्य कीड़े भी होते हैं, जो उनके लिए भोजन का स्रोत हो सकते हैं। इसके अलावा, कुछ कीड़े प्रकाश के पास आकर अपने शिकारी से बचने की कोशिश करते हैं।
माइग्रेशन (प्रवासन): कई कीड़े गर्मियों में माइग्रेशन करते हैं और लंबी दूरी तय करते हैं। इस दौरान, वे रात में उड़ते समय लाइट या आग को एक मार्गदर्शक के रूप में उपयोग कर सकते हैं।
इन सभी कारणों के मिश्रण से बारिश के दिनों में आग और रोशनी पर कीड़े ओर अधिक आकर्षित होते हैं।

AI (Artificial Intelligence) How To Learn
1. Data Collection and Pre-processing
Data Collection:
A lot of data is needed to train an AI system. This data can be collected from various sources, such as sensors, internet, human interaction, etc.
Pre-processing:
The data is cleaned and organized. This includes removing noise, normalizing the data, and bringing the data into a standard format.
2. Model Selection and Training
Model Selection:
There are different types of models in AI, such as Decision Trees, Neural Networks, and Support Vector Machines. The appropriate model is selected depending on the nature of the problem.
Model Training:
The selected model is trained on the collected data. During training, the model learns patterns and relationships from the data. This is often done by an algorithm, such as backpropagation in neural networks.
3. Model Testing and Validation
Model Testing:
The model is tested on new and unseen data to check how well it is working.
Validation:
The accuracy and performance of the model is measured. Various metrics are used for this, such as Accuracy, Precision, Recall and F1 score.
4. Prediction and Decision Making
Prediction:
Once the model is trained and tested, it is applied to real-world data. The model makes predictions based on the input data.
Decision Making:
Based on the predictions made by the model, the system makes decisions and takes action. For example, a self-driving car can decide to brake based on the signal.
5. Feedback and Learning
Feedback:
The system receives constant feedback, which helps it improve its performance. This feedback can be provided by humans or other sensors.
Learning:
The AI system constantly learns from new data and keeps updating its model. This is called continuous learning.
AI techniques and how they work
AI
