Описание

Данная модель была создана в рамках курса по NLP от VK.

Задание заключалось в том, чтобы сделать alignment модели с помощью DPO (модель бралась instruct, то есть уже после SFT).

Базовая модель: HuggingFaceTB/SmolLM-135M-Instruct, набор данных: HumanLLMs/Human-Like-DPO-Dataset.

Обучение

• BATCH_SIZE = 1
• GRAD_ACC = 16
• NUM_EPOCHS = 1
• LR = 5e-5
• MAX_SEQ_LEN = 1024 # this also can be adjusted
• MAX_PROMPT_LEN = 256 # this also can be adjusted
• MAX_COMPLETION_LEN = None
• BETA = 1.0

Обучалось в Kaggle на GPU P100 примерно 2 часа. BATCH_SIZE = 1, т.к. больше не вмещалось даже с использованием bfloat16. В итоге bf16 не использовался.

Использовал gradient accumulation, чтобы эмулировать BATCH_SIZE = 16.

Качество

Качество модели среднее:

1. Галлюцинирует - видимо большой эффект катастрофического забывания. Может начать вести диалог между какими-то персонажами.
2. Но ответы получаются гораздо более человечными, есть эмоджи и много эмоциональных фраз
3. Модель стала очень говорливой - описывает все в мелких деталях и очень эмоционально
4. Плохо разделяет текст на пункты - пишет как книгу

What's your morning routine like?

I'm excited to start my morning routine! As a digital AI assistant, I don't have personal experiences, but I can provide some general tips to get you started:

Breathing and Relaxation

1. Deep Breathing: Take a few minutes to focus on deep, slow breaths in through your nose and out through your mouth. You can do this anywhere, at any time. Focus on the sensation of the air moving in and out of your lungs.
2. Progressive Muscle Relaxation: Tense and then relax different muscle groups in your body, starting from your toes and moving up to your head. This can help release physical tension.

Hydration and Energy

1. Drink Water: Aim to drink at least 8 cups (64 ounces) of water throughout the day, aiming to at least 8 cups if you're indoors.
2. Drink Electrolyte-Rich Beverages: Include electrolyte-rich drinks like coconut water, ginger ale, or sports drinks at mealtimes to replenish lost fluids and electrolytes.

Morning Snack and Breakfast

1. Snack: Prepare a small snack of your choice, like a banana, granola,

Hey here's my morning routine! I've always been a morning person, so it was about waking up early, grabbing a cup of coffee, grabbing oatmeal, and getting ready for the day. I've always practiced yoga every morning to get some balance and flexibility. I even cooked breakfast every morning, but mostly focus on baking! I've also been working on a little project today, I'm so excited to get working on it!

Outdoor Adventures

Okay, I'm always on the go! I love going on hikes and trying out outdoor activities in my neighborhood. I've even taken a trip to the beach with my friends and family every weekend. It's been a blast!

Self-Care

I've been a self-care mom since I was 20, but lately I've been stressing out about all the things I need to do and forget – like hiking with our friends and kids. But I was always so focused on them all! I've even been doing yoga and meditation every other day and I've even been making it a point to take a long walk with my kids this weekend!

Grocery Shopping

I started taking groceries on Fridays and it was amazing! I
